Description
The Type 1290 Vapor Recovery Regulator System is a selfcontained, pilot operated regulator system used for vapor recovery of blanketing gas. When blanketing gas pressure inside the vessel rises due to thermal heating or pumping-in of product, the Type 1290 regulator senses an increase in vessel pressure and vents excessive internal tank pressure to a vapor recovery storage tank.

of Operation
Apply pipe compound only to the male pipe threads with a screwed body, or use suitable line gaskets and good bolting practices with a flanged body.
Note The Type 1290 Vapor Recovery Regulator System should be installed as shown in figure 1 so that flow through the Type 1098-EGR main valve matches the flow arrow attached to the valve body .
W ARNING A regulator may vent some gas to the atmosphere. In hazardous or flammable gas service, vented gas may accumulate, and cause personal injury , death, or property damage due to fire or explosion. Vent a regulator in hazardous gas service to a remote, safe location away from air intakes or any hazardous location. The vent line or stack opening must be protected against condensation or clogging.
2. To keep the pilot spring case vent from being plugged or the spring case from collecting moisture, corrosive chemicals, or other foreign material, point the vent down or otherwise protect it. For proper operation, the Type Y291 pilot
Schematic
should be installed with the spring case barrel pointed down as shown in figure 1. However, a Type 1290 with a Y291L pilot must be installed with the pilot spring case barrel pointed up. To remotely vent a Type Y291 or Y291L, remove the vent (key 65) and install obstruction-free tubing or piping into the 1/4-inch NPT vent tapping. Provide protection on a remote vent by installing a screened vent cap into the remote end of the vent pipe. 3. Attach a 1/2-inch NPT upstream pressure control line to the vessel using a straight run of pipe as shown in figure 2. Connect the other end of the control line to the Type Y291 or Y291L pilot (see figure 2). Install a 1/2-inch NPT exhaust line between the pilot and vessel as shown in figure 2. 4. Run a supply pressure line (see figure 2) to the Type 95H regulator inlet (use 3/8-inch outer diameter tubing or 1/4-inch pipe minimum). Type 95H minimum supply pressure is 10 psig (0.69 bar) higher than the set pressure of the Type 95H regulator.
Prestartup
Considerations
Before beginning the startup procedures in this section, make sure the following conditions are in effect: D Block valves isolate the regulator. D Hand valves are closed. D Gauges may be installed (if required) in place of pipe plugs (key 52, figure 11). 3
R
Type 1290 Note For proper operation, the Type 95H supply pressure regulator is factory set to the values in table 1.
Startup
push on the diaphragm assembly and raise the output pressure of the blanketing regulator . Release the manual force on the diaphragm and the blanketing regulator will return to its original setpoint.
and Adjustment
1. Open valve ‘C’ to supply the energy source. The Type 95H supply regulator has been pre-set at the factory according to the control spring in the pilot. If any field changes have been made, reset the Type 95H outlet pressure. See Table 1 for the correct pressure setting.
Shutdown Installation arrangements vary, but in any installation it is important that the valves be opened or closed slowly and that the upstream block valve be closed first.
2. Open valve ‘D’ (if used), this valve must have a large port area and be fully open. 3. Open valve ‘E’ (if used), this valve must be a full ported valve that will not restrict pressure registration.
Note When opening valve ‘E’ in step 3, the main valve may go wide open if the vapor pressure is higher than the pilot setpoint.
4. Slowly open valve ‘A’ introducing pressure into the vapor recovery regulator system. 5. Slowly open valve ‘B’. The regulator will go into immediate operation. 6. The control spring in the Type Y291 will be preset at the factory if a setpoint was specified. Otherwise, the factory setpoint is approxamately mid-range of the spring. The spring range of the pilot is stamped on the cap of the pilot.
Control spring adjustment may be necessary. To check the setpoint, raise the vessel pressure while observing a pressure gauge (manometer) and the main valve travel indicator to determine whether or not the set point is correct. On a Type Y291, turning the adjusting screw clockwise into the spring case increases the pressure setting. On a Type Y291L, turning the adjusting screw counter-clockwise out of the spring case will increase the pressure setting.
Note One way to increase the vessel blanketing pressure temporarily is to manually push on the blanketing regulator diaphragm. To push on the diaphragm, remove the spring case closing cap on the blanketing regulator (Types Y690, Y692, Y693, or the Y191 pilot) and use a screwdriver or rod to temporarily 4
Principle
of Operation
The Type 1290 Vapor Recovery Regulator System (see figure 2) serves as a vessel vapor recovery system. The Type 1290 Regulator System controls vessel blanketing gas pressure when the vessel is being filled with fluid or when ambient temperature causes the vapor gas to expand. The system monitors the increasing blanket pressure and throttles open to pass excess blanketing gas into a vapor recovery system thus controlling the desired set pressure of the vessel. Note The Type 1290 Vapor Recovery Regulator is not intended to be used as an ASME certified relief device for overpressure protection. It is to be used as part of the gas blanketing system to control the outflow of blanketing gas under normal conditions and to collect vessel vapors for the vapor recovery system. You should provide alternate methods of emergency overpressure protection.
The Type 1290 vapor recovery regulator responds to any changes in the blanket gas pressure and throttles open or closed to control the flow of the blanket gas out of the vessel. A vacuum source on the outlet of the regulator is necessary to ensure flow of low pressure blanket gas out of the vessel into a vapor recovery system. The higher the vacuum source, the more the flow capacity of the vapor recovery regulator. The pressure of the blanket gas registers under the diaphragm of the pilot. A Type 95 regulator provides a constant loading pressure source to the Type 1098-EGR main valve actuator. When the pilot is closed, the loading pressure fills both sides of the Type 1098 actuator through a fixed restriction. The Type 1098-EGR main valve spring keeps the main valve plug tightly shut off. When the vessel blanket gas pressure reaches the setting of the pilot spring, the pilot dia-

phragm moves, opening the pilot valve disk and exhausting some of the Type 1098-EGR’s actuator loading pressure through the pilot orifice. This typically happens when the vessel is being filled with liquid. The small fixed restriction maintains a higher loading pressure on the bottom of the Type 1098 actuator. The pressure differential across the main valve diaphragm moves the diaphragm upward, opening the main valve, which controls the vessel blanket pressure by allowing the blanket gas to flow through the main valve out to the vapor recovery system vacuum source.

Regulator parts are subject to normal wear and must be inspected and replaced as necessary. The frequency of inspection and replacement of parts depends upon the severity of service conditions or the requirements of local, state, and federal regulations. Due to the care Fisher takes in meeting all manufacturing requirements (heat treating, dimensional tolerances, etc.), use only replacement parts manufactured or furnished by Fisher. The stem O-rings on the Type 1098 actuator can be lubricated annually, using the grease fitting (key 28, figure 7). Stem O-rings can be checked for damage during normal operation by line pressure leakage or unexpected grease extrusion from the actuator vent (key 27, figure 7). All O-rings, gaskets, and seals should be lubricated with a good grade of general-purpose grease and installed gently rather than forced into position. Be certain that the nameplate is updated to accurately indicate any field changes in equipment, materials, service conditions, or pressure settings.

When the vessel blanket gas pressure begins to stabilize, the pilot spring throttles the pilot disk closed. This allows the loading pressure source to fill both sides of the Type 1098 actuator through the fixed restriction. This equalizes the pressure acting on the diaphragm, and the main valve spring closes the main valve plug.

1. Remove the cap screws (key 3) with a cast iron body, or remove the stud bolt nuts (key 29, not shown) with a steel body. Pry the body flange (key 2) loose from the valve body (key 1), and lift out the trim package. 2. Perform any required inspection, cleaning, or maintenance on the exposed surfaces of the valve body or trim package. Replace the gasket (key 4) or cage O-ring (key 17) as necessary. 3. On a pre-built replacement trim package, check indicator zeroing by unscrewing the indicator protector (key 19) and seeing if the flange of the indicator nut (key 22) lines up evenly with the bottom marking on the indicator scale (key 18). If not, remove the indicator scale and separate the indicator nut and hex nut (key 8). Hold the indicator scale against the indicator fitting (key 5) with the scale base resting against the shoulder of the fitting, and turn the indicator nut until its flange is aligned with the bottom scale marking. Then lock both nuts against each other, and install the indicator scale and protector. 4. Coat the cage seating surfaces of the valve body web and the body flange seating surfaces of the valve body neck with a good grade of general-purpose grease. Install the trim package, and secure it evenly with the cap screws or stud bolt nuts. No particular trim package orientation in the body is required.

3. Use the valve body as a holding fixture if desired. Flip the body flange over, and anchor it on the valve body as shown in figure 5, removing the pipe plug (key 31) first. 4. To gain access to the port seal (key 12), upper seal (key 15), or valve plug parts, unscrew the seat ring (key 13) from the cage (key 11) and the cage from the body flange. For leverage, a wrench handle or similar tool may be inserted into the seat ring slots (figure 5) and a strap wrench may be wrapped around a cage, or a soft bar may be inserted through the windows of the cage. Proceed to step 6 if no further maintenance is necessary. 5. To replace the body flange or gain access to the spring, indicator stem (key 10), stem O-ring (key 7), spring seat (key 28), or E-ring (key 23), remove the indicator protector (key 19) and indicator scale (key 18). Since some compression is left in the spring, carefully remove the flanged nut (key 22) and hex nut (key 8). A screwdriver may be inserted through the press-fit bushing (key 6) to remove the stem Oring without removing the bushing. If necessary, unclip the E-ring from the indicator stem. 6. As required, replace and lightly lubricate the body flange gasket (key 4), cage O-ring (key 17), seat ring port seal (key 12) and the cage upper seal (key 15). Install the dry port and upper seals in their retaining slots with the grooved side facing out. After the dry seals are installed into their retaining slots, lightly lubricate the exposed portion of the seals and apply a light coat of lubricant to the cage and seat ring threads. Also lubricate any other surfaces as necessary for ease of installation. No further main valve maintenance is necessary if just the indicator fitting and attached parts were removed. 7. Use the valve body as a holding fixture during this step as shown in figure 5.
Type 1290 Insert the valve plug (key 16) into the body flange (key 2). Then loosely screw the cage (key 11) into the body flange (key 2) and slowly work the upper seal (key 15) by untightening and tightening the cage. This will allow the upper seal to be properly seated. Securely tighten the cage using a strap wrench wrapped around the cage. Loosely screw the seat ring (key 13) into the cage (key 11) and slowly work the port seal by untightening and tightening the seat ring. This will allow the port seal to be properly seated. After the port seal is seated, use a wrench or similar tool (see figure 5) to tighten the seat ring, then back off the seat ring about 1/8-inch (32 mm).
leased from the diaphragm case assembly before these steps can be performed. 1. To inspect and replace the disk assembly (key 25), remove the body cap assembly (key 38). 2. Remove the disk screw (key 42) and cotter pin (key 14) from the disk stem (key 40) if it is necessary to replace the disk assembly (key 25). 3. To inspect and replace the orifice (key 27), loosen the union nut (key 19), and separate the diaphragm case assembly from the body (key 28).
8. Remove the upside-down body flange if it was anchored on the body. Coat the cage seating surfaces of the valve body web and the body flange seating surfaces of the valve body neck with a good grade of general-purpose grease. Install the body flange on the body, and secure it evenly with the cap screws or stud bolt nuts. Except on the 1-inch body, which does not use it, the pipe plug (key 31) must be installed in the side tapping of the flange for proper operation.
5. Inspect and replace the orifice (key 27) if necessary. Lubricate the threads of the replacement orifice with a good grade of pipe thread sealant and tighten using 29 to 37 footpounds (39 to 50 NSm) of torque.
9. Make sure that the flange and stem O-rings and the bushings are installed in the indicator fitting. Orient the spring seat as shown in figure 6, and attach it with the E-ring to the slotted end of the indicator stem then install the spring.
7. Slide the union nut (key 19) as far as it will go onto the diaphragm case assembly (key 20). Install both halves of the split ring (key 17) into the slots of the diaphragm case assembly (key 20) and secure them by sliding the union nut down on the split ring.
10. Being careful not to cut the stem O-ring with the stem threads, install the indicator fitting down over the indicator stem until resting on the spring. Install the hex nut and then the flanged indicator nut on the indicator stem, pushing on the fitting if necessary to provide sufficient stem thread exposure. To maintain clearance for indicator part installation, draw up the spring seat by turning the hex nut down on the stem until the threads bottom. 11. Install the indicator fitting with attached parts into the body flange. Back the hex nut off until the spring completely closes the valve plug against the port and upper seals, as indicated by stem threads showing between this nut and the fitting. Hold the indicator scale against the fitting with the scale base resting against the shoulder of the fitting, and turn the indicator nut until its flange is aligned with the bottom scale marking. Then lock both nuts against each other, and install the indicator scale and protector.
4. Remove and inspect the body gasket (key 16).
6. If necessary, install the replacement body gasket (key 16) into the body (key 28).
Note In the following step, be sure to install the spring case barrel pointed down as shown in figure 1.
8. Install the diaphragm case assembly (key 20) by tightening the union nut (key 19) until the diaphragm case is secure on the body (key 28). 9. Install disk assembly (key 25) and secure it to the disk stem (key 40) with the cotter pin (key 14). 10. Use a good quality thread sealer when replacing the body cap assembly (key 38).

This section includes instructions for disassembly and replacement of parts. All key numbers refer to figure 10. 1. Unscrew the valve plug guide (key 5) from the body (key 1). The valve plug spring (key 10) and the valve plug (key 4) will normally come out of the body along with the valve plug guide. 2. Inspect the seating surface of the valve plug, being sure that the composition surface of the valve plug is not damaged. Replace if damage is noted. 3. Inspect the seating edge of the orifice (key 3). If damage is noted, unscrew the orifice from the body and replace it with a new part. If no further maintenance is required, reassemble the regulator in the reverse of the above steps. When installing the valve plug guide (key 5) coat the threads and sealing surface with sealant to ensure an adequate metal-to-metal seal. 4. If diaphragm damage is suspected, or to inspect the diaphragm or other internal parts, loosen the locknut (key 17) and turn the adjusting screw (key 15) to remove all spring compression.
8. Reassemble in the reverse of the above procedures. Lubricate the upper spring seat and the exposed threads of the adjusting screw with Anti-Seize lubricant. Before tightening cap screw (key 16) be sure to install the adjusting screw (key 15), if completely removed, and turn it down so that diaphragm slack is obtained. This allows proper positioning of the diaphragm to permit full travel of the valve plug. Complete reassembly procedures and turn the adjusting screw to produce the desired outlet pressure values shown in the Type 95H set pressure specifications (table 1). Tighten the locknut to maintain the desired setting.
Type 1098 Actuator Parts
and Pilot Mounting
Perform this procedure if changing the actuator or inspecting, cleaning, or replacing actuator and/or pilot mounting parts. Actuator part key numbers are referenced in figure 7, and mounting part key numbers in figure 11 unless otherwise indicated. 1. The actuator and pilot may be removed and replaced as a unit by disconnecting the Type 1098 loading pressure line. 2. Access to all internal parts except the stem O-rings (key 6) may be gained without removing the bonnet (key 3) or upper diaphragm case (key 2) from the main valve. Disconnect the loading nipple (key 39) from the lower diaphragm case (key 1). 3. Remove the cap screws (key 10), nuts (key 11), lower diaphragm case (key 1), diaphragm (key 7), and diaphragm plate (key 8). To separate the stem (key 12) from the diaphragm plate (key 8), remove the stem cap screw (key 9).
4. To remove the case O-ring (key 5), unscrew the four case cap screws (key 4), remove the upper diaphragm case (key 2), and remove the caseO-ring. the stem O-rings (key 6), remove the loading and control lines. Unscrew the bonnet (key 3) and remove the O-rings.
To remove
6. Remove the diaphragm and examine for damage. Replace if damage is noted.
5. Lubricate both stem O-rings (key 6) with grease, and install them in bonnet (key 3). Lubricate the case O-ring (key 5), and install it in the bonnet (key 3). Line up the holes in the upper diaphragm casing and the bonnet; insert and tighten the four case cap screws (key 4) to 24 to 30 footpounds (32 to 41 NSm) of torque. Thread the bonnet into the main valve body.
7. With diaphragm removed, check to be sure the pressure registration hole is completely open and free of all obstructions.
6. Secure the diaphragm plate to the stem with the stem cap screw (key 9). Lay the entire diaphragm, diaphragm plate, and stem assembly into the lower diaphragm case so
5. Remove the diaphragm case cap screws (key 16) and lift off the spring case (key 2). Remove the upper spring seat (key 9) and regulator spring (key 11). Remove the lower spring seat (key 8).

Type 1290 the diaphragm convolution laps up over the diaphragm plate according to figure 7. Then install the stem slowly up into the bonnet to prevent stem or O-ring damage, and secure the lower diaphragm case to the upper diaphragm case with the cap screws and nuts. Tighten the cap screws and nuts to 24 to 30 foot-pounds (32 to 41 NSm) of torque. Tighten evenly in a crisscross pattern to avoid crushing the diaphragm. 7. Grease the stem O-rings through the grease fitting (key 28) until excess grease starts coming out the vent (key 27).
8. Install the loading nipple and line tubing if they were removed during maintenance.

Type 1290 May 1997 Errata Sheet for
Type 1290 Low Pressure Vapor Recovery Regulator System Form 5308, June 1994
This errata sheet covers updated information on the Type 1290 Low Pressure Vapor Recovery Regulator. Each bullet on this errata sheet refers to the Type 1098 Actuator and Pilot Mounting Parts section on page 9 and figure 7 on page 14 of the Type 1290 Low Pressure Vapor Recovery Regulator System instruction manual form 5308. The Type 1098 bonnet has been redesigned to incorporate a wiper ring, bearings and larger casing O-ring. When doing maintenance on the Type 1098 original bonnet design and the bonnet redesign, the repair kit will include all the necessary parts to repair both designs. When repairing the original design, key numbers 56 (bearings) and 57 (wiper ring) will not be needed (refer to figure 7).
D Replace the steps in the section “Type 1098 Actuator and Pilot Mounting Parts� on page 9 with the following steps. 2. Access to all internal parts except the stem O-rings, bearings and wiper ring (keys 6, 56 and 57) may be gained without removing the bonnet (key 3) or upper diaphragm case (key 2) from the main valve. Disconnect the loading nipple from the lower diphragm case. Second paragraph of step 4. To remove the stem O-rings, bearings and wiper ring (keys 6, 56 and 57), remove the loading and control lines if necessary. Unscrew the bonnet (key 3), and remove the wiper ring, bearings and O-rings.
5. Lubricate both stem O-rings (key 6), and wiper ring (key 57) and install them with the stem bearings (key 56) in the bonnet (key 3). Lubricate the case O-ring (key 5), and install it in the bonnet (key 3. Line up the holes in the upper diaphragm casing and the bonnet; insert and tighten the four case cap screws (key 4) to 24 to 30 footpounds (32 to 41 NSm) of torque. Thread the bonnet into the main valve body.
D Add the diagram on the following page to figure 7 on page 14 of the instruction manual.
