Type 92S

Installation WARNING Personal injury, equipment damage, or leakage due to escaping steam or bursting of pressure-containing parts may result if this regulator is overpressured or is installed where service conditions could exceed the limits given in table 1 and on the appropriate nameplates, or where conditions exceed any ratings of the adjacent piping or piping connections. To avoid such injury or damage, provide pressure-relieving or pressure-limiting devices to prevent service conditions from exceeding those limits.

16A7958-B A2607-1

Additionally, physical damage to the regulator could result in personal injury and property damage due to escaping steam. To avoid such injury and damage, install the regulator in a safe location.

1. Only personnel qualified through training and experience should install, operate, and maintain a Type 92S regulator. Before installation, make sure that there is no damage to, or debris in, the regulator. Also make sure that all tubing and piping are clean and unobstructed.

2. A Type 92S regulator may be installed in any orientation, as long as flow through the regulator matches the direction of the arrow on the main valve body. However, the regulator should not be installed in a tall, vertical pipeline where condensate could collect and create a pressure head affecting regulator performance.

3. Apply steam-compatible pipe compound to the male pipeline threads for a screwed body, or use suitable line gaskets for a flanged body. Use acceptable piping procedures when installing the regulator.

4. If continuous operation of the system is required during inspection and maintenance, install a three-valve bypass around the regulator. If the flowing medium contains solids, install a properly sized strainer upstream of the regulator.

Note A clogged vent on the spring case of a standard Type 6492H or 6492L pilot may cause the regulator to function improperly. Install and maintain a regulator with a standard pilot so that the spring case vent stays clear.

Figure 3. Typical Installations

5. As shown in figure 3, connect a control line as large as possible but no smaller than 3/8-inch (9.5 mm) diameter bushed down to the 1/4-inch NPT connection in the cylinder spacer (1, 1-1/2, or 2-inch body size) or the pilot body (2-1/2, 3, 4, or 6 x 4-inch body size).

6. Locate the control line connection at least 10 pipe diameters away from the regulator or swage and in a section of straight pipe.

7. Do not locate the control line connection in a gate, plug, or check valve, in an elbow, swage, or other area of the pipeline where turbulence or abnormal velocities may occur, or in a large-volume vessel that can cause noticeable control lag.

8. Slope the control line away from the pilot to let condensate drain into the pipeline.

9. Install a shutoff valve (not a needle valve) in the control line to isolate the pilot during maintenance.

10. Install a pressure gauge in the control line, or near the regulator, to aid in setting the outlet pressure.

Type 92S 11. With a pressure-loaded or on-off pilot, connect the pressure-loading or on-off piping or tubing to the 1/4-inch NPT connection in the tapped pilot spring case.

12. The pressure setting of the regulator is determined by: D The pilot control spring adjustment on a standard pilot, or D The pressure-loading device in conjunction with the control spring adjustment on a pressure-loaded pilot. In both cases, check these settings to make sure they are correct for the application.

Startup and Adjustment Note The maximum inlet pressure for a specific construction is stamped on the main valve nameplate. Use pressure gauges to monitor upstream and downstream pressures during startup.

4. Open the control line shutoff valve.

Note Before finally adjusting the pilot setting, allow enough time for the pilot and main valve to heat up and boil off any condensate buildup.

5. If a bypass is used, slowly close the bypass line block valve.

6. Perform the adjustment procedure until the downstream pressure reaches the desired setting.

Startup with Existing Regulator Installation After Normal Shutdown 1. Open the upstream and downstream block valves and let the regulator take over control at the existing pilot control spring setting.

2. If a bypass line is used, slowly control the bypass line block valve.

Adjustment On a regulator with any kind of Type 6492H or 6492L pilot, loosen the hex nut (key 16, figure 5). Turn the adjusting screw (key 15, figure 5) into the spring case to increase the downstream pressure. Turn the adjusting screw out of the spring case to decrease the downstream pressure. When the required downstream pressure is maintained for several minutes, tighten the hex nut to lock the adjusting screw in position.

On a regulator with a pressure-loaded Type 6492H or 6492L pilot, also refer to the instruction manual of the pressure-loading device for downstream pressure adjustment procedures. Make sure that the combined pilot control spring setting pressure and spring case loading pressure do not exceed 150 psig (10 bar) for the Type 6492H pilot or 25 psig (1.7 bar) for the Type 6492L pilot. For example, a 5 psig (0.34 bar) spring setting and a 10 psig (0.69 bar) pressure loading result in a regulator pressure of 15 psig (1.0 bar).

Shutdown 1. If a bypass line is used, slowly open the bypass line block valve while monitoring the downstream pressure.

2. Close the control line shutoff valve.

3. Close the downstream block valve.

4. Close the upstream block valve.

5. If a pressure-loaded or on-off pilot is used, close the needle valve to the pilot.

6. Vent the regulator and control line to release any trapped pressure.

Startup with New Regulator Installation 1. Remove all pilot control spring compression by turning the adjusting screw out of the spring case according to the adjustment procedure.

2. Slowly open the upstream block valve.

3. Open the downstream block valve.

Principle of Operation Pilot supply pressure is piped from the main valve inlet (figure 4) to the pilot inlet connection. Downstream pressure registers on the main valve pistons through the downstream control line and then on the pilot diaphragm.

Figure 4. Operational Schematics

When increased downstream demand lowers the downstream pressure to a valve below the setting of the pilot control spring, this spring forces the pilot valve plug open to increase the loading pressure on the main valve pistons.

At the same time, the increased demand lowers the downstream pressure on the main valve piston(s). This opens the main valve plug, increasing flow to the downstream system to satisfy the increased demand and to restore downstream pressure to the setting of the pilot control spring.

Decreased downstream demand increases the downstream pressure registered on the pilot diaphragm. The increased pressure overcomes the force of the pilot control spring and allows the pilot valve plug spring to close the pilot valve plug. As the pilot valve plug closes, excess loading pressure bleeds to the downstream system through the pilot bleed restriction. At the same time, decreased downstream demand increases the downstream pressure registered on the main valve piston(s). This allows the main valve spring to close the main valve plug, reducing flow to the downstream system in response to the decreased demand.

With a pressure-loaded or on-off pilot, the operation is the same as for a standard pilot except that the pilot control spring force on the pilot valve plug is aided by pneumatic pressure from the loading device or solenoid valve.

Maintenance Regulator parts are subject to normal wear and must be inspected periodically and replaced as necessary. The frequency of inspection and replacement depends upon the severity of service conditions and upon applicable codes and government regulations.

WARNING To avoid personal injury resulting from sudden release of pressure, isolate the regulator from all pressure and cautiously release trapped pressure from the regulator before attempting disassembly.

Type 6492H and 6492L Pilots These procedures are to be performed if inspecting, cleaning, or replacing any pilot parts, or if cycling, erratic control, or too high or too low an outlet (control) pressure is noted.

Perform only those procedures in this section required to correct the problem. Key numbers refer to figure 5 unless otherwise noted.

Type 92S Note Before performing any maintenance, loosen the hex nut (key 16), if used, and turn the adjusting screw (key 15) or handwheel (key 31) counterclockwise until all compression is removed from the control spring (key 12).

Remove the pilot from the pipe nipple and connectors (keys 82 and 83, figure 7).

1. Unscrew the plug guide (key 2). Remove the screen (key 77), plug (key 4), plug spring (key 3), and stem (key 7). Unscrew the seat ring (key 5). Examine the seat ring and plug seating surfaces for damage.

2. Clean and replace parts as necessary. Apply Led-Plate No. 250(1) sealant or equivalent to the seat ring threads.

Thread the seat ring into place and tighten it to between 19 and 25 foot-pounds (26 and 34 NSm) of torque.

3. Handle the parts carefully, and place the plug spring (key 3) in the plug guide (key 2). Slide the plug (key 4) over the spring and into the plug guide. Place the screen (key 77) onto the plug guide. Place the stem (key 7) in the center hole of the plug guide. Apply Led-Plate No. 250 sealant or equivalent to the plug guide threads, and screw the guide plus attached parts into the body (key 1).

11. Lubricate the upper spring seat and the exposed threads of the adjusting screw with Never-Seez(2) lubricant or equivalent. Install the lower spring seat (key 11, Type 6492H pilot only) or diaphragm assembly (key 24, Type 6492L pilot only), control spring (key 12), upper spring seat (key 13), and spring case (key 14). Insert and tighten the cap screws (key 17) to between 12 and 18 foot-pounds (16 and 24 NSm) of torque, using a crisscross bolting pattern.

12. When pilot maintenance is complete, refer to the Startup section to put the regulator back in operation and adjust the pressure setting.

Type 92S Main Valve Perform these procedures if replacing the piston(s), cylinder(s), stem(s), seals, valve plug, or seat ring. All key numbers are referenced in figure 6 except where otherwise indicated. Instructions are given for complete disassembly and assembly. Disassemble the main valve only as far as necessary to complete the required maintenance. Then, begin the assembly procedure at the appropriate step.

4. Remove the pipe plug and restriction (keys 74 and 76).

Clean or replace the restriction as necessary.

5. Sparingly apply Led-Plate No. 250 sealant or equivalent to the threads of the restriction, and thread the restriction into place.
