Figure 1. Type 1008 Handwheel Actuator
Introduction
This instruction manual presents principle of operation, installation, maintenance, and parts list for the Type 1008 handwheel actuator (figure 1). Refer to separate instruction manuals for information about other equipment and accessories used with these actuators. Only personnel qualified through training or experience should install, operate, and maintain a Type 1008 actuator. If you have any questions about these instructions, contact your Fisher Controls sales office or sales representative before proceeding.
Description The Type 1008 is a handwheel actuator for processes requiring a throttling valve that can be manually oper-
ated and set. The Type 1008 handwheel actuator is available in sizes 30, 40, 50, 80, and 100, and can be mounted on Fisher Controls easy-e valves. The Type 1008 handwheel actuator converts rotary motion of the handwheel to linear motion of the valve plug stem. Because the stem does not revolve, the valve plug contacts the same seating surface with each stroke. Sizes 40, 50, 80, and 100 include two thrust bearings to make rotation easier. Turn the handwheel counterclockwise to open the valve regardless of valve plug action. All sizes of the Type 1008 handwheel actuator except size 100 are reversible following the Reversing Handwheel procedures.

1. For S31600 (316 stainless steel) stems at 100_F (38_C). 2. Actuator limit.
Specifications Refer to table 1 for Specifications of the Type 1008 handwheel actuator. Refer to the actuator nameplate for information about a specific actuator.
5. Temporarily connect the valve plug stem to the stem connector assembly (key 24) and tighten the cap screws into the stem connector. 6. Use the handwheel (key 28) to move the valve plug into the fully open position, as indicated by the travel indicator disk (key 20) on the travel indicator scale (key 27). 7. Remove the stem connector assembly (key 24).
Installation The Type 1008 handwheel actuator can be installed horizontally, vertically, or at any orientation in between. However, if supplied with a Tejax position indicator (see figure 6), the actuator must be installed in a horizontal position. When an actuator and valve body are shipped together as a control valve assembly, the actuator is normally mounted on the valve. Follow the valve body instructions when installing the control valve in the pipeline. If the actuator is shipped separately or if it is necessary to mount the actuator on the valve, perform the Actuator Mounting procedures.
Actuator Mounting Key numbers refer to figure 2 for size 30, figure 3 for sizes 40 and 50, figure 4 for size 80 or figure 5 for size 100. 1. Place the actuator on the body bonnet and tighten the yoke locknut or the actuator mounting hex nuts.
8. Size 30: Turn the handwheel (key 28) counterclockwise until the stem connector assembly (key 24) almost touches the top of the yoke; Sizes 40, 50, and 80: Turn the handwheel (key 28) counterclockwise as far as it will go; Size 100: Turn the handwheel (key 28) counterclockwise (for push-down-to-close valves) or clockwise (for push-down-to-open valves) as far as it will go.
CAUTION Incomplete engagement of both valve stem and stem screw assembly (key 38) or size 100 power screw (key 5) in the stem connector can result in stripped threads or improper operation. Be sure that the length of each stem clamped in the stem connector is equal to or greater than the diameter of that stem.
3. Adjust the travel indicator scale (key 27) so that the two screws (key 19) are centered in the slots.
9. Connect the valve plug stem to the stem connector assembly (key 24). Ensure that the bottom of the stem connector is touching or nearly touching the travel indicator disk (key 20). Tighten the stem connector (key 24) cap screws and lock the hex nuts (key 29) against the travel indicator disk (key 20) and stem connector.
4. Screw the hex nuts (key 29) onto the valve plug stem and place the travel indicator disk (key 20) onto the stem above the hex nuts. Adjust the nuts until the travel indicator disk (key 20) points to the closed position on the scale.
10. Rotate the handwheel until the valve plug seats. Adjust the travel indicator scale (key 27) with two screws (key 19) so that the travel indicator disk (key 20) points to the closed position on the scale. Tighten the two screws.
2. Ensure the valve plug is on its seat.

Type 1008 Position Indicator Mounting
Lubrication
The Tejax position indicator is available on sizes 30, 40, and 50 Type 1008 handwheel actuators. It must be mounted in a horizontal position to function correctly. To set the position indicator:
The interior parts of a Type 1008 handwheel actuator should be lubricated on a regular schedule with a quality gear lubricant. The interior parts should also be lubricated whenever handwheel rotation becomes difficult.
1. Seat the valve plug. 2. Loosen the four screws holding the dial indicating unit in place.
Disassembly
3. Turn the dial until both hands are at the ‘‘Shut’’ (Zero) position.
Parts are subject to normal wear and must be inspected periodically. The following procedure describes actuator disassembly for general inspection and replacement.
4. Tighten the four screws.
For Size 30: 1. Remove the stem connector assembly (key 24).
The long pointer indicates fractions of a turn; the small pointer counts the number of full turns. The position indicator requires no lubrication.
2. Unscrew the set screw (key 13) from the yoke (key 26) and remove the steel balls (key 33) through the threaded hole. Note
Be careful not to lose the ball (key 33) and spring (key 34) as the handwheel is removed.
Maintenance Actuator parts are subject to normal wear and must be inspected and replaced when necessary. The frequency of inspection and replacement depends on the severity of service conditions. Because of the care Fisher Controls takes in meeting all manufacturing requirements (such as heat treating and dimensional tolerances), use only replacement parts manufactured or furnished by Fisher Controls.
3. Remove the handwheel (key 28) and stem screw assembly (key 38) from the yoke (key 26). 4. Unscrew the handwheel (key 28) from the stem screw assembly (key 38). For Sizes 40 & 50: 1. Remove the stem connector assembly (key 24). 2. Unscrew the hex nut (key 14) and remove the washer (key 41) and lockwasher (key 42).
WARNING Avoid personal injury or damage to property from sudden release of pressure or uncontrolled process fluid. Before performing any maintenance operations: D Isolate the valve from the process, and relieve process pressure from both sides of the valve. D Use lock-out procedures to be sure the above measures stay in effect while you work on the equipment. Key numbers refer to figure 2 for size 30, figure 3 for sizes 40 and 50, figure 4 for size 80 or figure 5 for size 100.
Note
Be careful not to lose the ball (key 33) and spring (key 34) as the handwheel is removed. 3. Remove the handwheel (key 28) from the stem screw assembly (key 38). 4. Loosen the set screw (key 13) and unscrew the bearing retainer (key 44). 5. Remove the stem screw assembly (key 38), thrust bearings (key 2), and nut (key 43) from the yoke (key 26). 6. Remove the nut from the stem screw assembly (key 38) to reach the remainder of the parts. For Size 80: 1. Remove the stem connector assembly (key 24).
