Description
The 1008 is a handwheel actuator for processes requiring a throttling valve that can be manually operated and set. The
1008 handwheel actuator is available in sizes 30, 40, 50, 80, and 100, and can be mounted on easy‐et valves.
The 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 1008
handwheel actuator except size 100 are reversible following the Reversing Handwheel procedures in this instruction
manual.
Specifications
Refer to table 1 for 1008 handwheel actuator specifications. Refer to the actuator nameplate for information about a
specific actuator.
Installation
WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.
The 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.
2. Ensure the valve plug is on its seat.
3. Adjust the travel indicator scale (key 27) so that the two screws (key 19) are centered in the slots.
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.
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).
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.
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.
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.
Position Indicator Mounting
The Tejax position indicator is available on 1008 handwheel actuators, sizes 30, 40, and 50. It must be mounted in a
horizontal position to function correctly. To set the position indicator:
1. Seat the valve plug.
2. Loosen the four screws holding the dial indicating unit in place.
3. Turn the dial until both hands are at the “Shut” (Zero) position.
4. Tighten the four screws.
The long pointer indicates fractions of a turn; the small pointer counts the number of full turns. The position indicator
requires no lubrication.

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.
WARNING
Avoid personal injury from sudden release of process pressure. Before performing any maintenance operations:
D Do not remove the actuator from the valve while the valve is still pressurized.
D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal
injury.
D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure
on both sides of the valve. Drain the process media from both sides of the valve.
D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
D The valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the
pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings, or when
loosening the packing box pipe plug.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
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.
Lubrication
The interior parts of a 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.
Disassembly
Parts are subject to normal wear and must be inspected periodically. The following procedure describes actuator
disassembly for general inspection and replacement.
For Size 30:
1. Remove the stem connector assembly (key 24).
2. Unscrew the set screw (key 13) from the yoke (key 26) and remove the steel balls (key 33) through the threaded
