IMPORTANT
• Electric actuators – If an electric actuator is used, route the wire harness away from potentially hot
and/or moving parts. Secure the harness every 10” – 12” (254mm – 309mm) to prevent excessive
movement.
• Testing – After installation, verify that the valve cycles properly from fully OPENED to fully
CLOSED without excessive effort. If equipped with a hand wheel or electric control, verify that
the indicator lights sequence properly, indicating valve OPEN, CLOSE, or in between. Pressure
test valve connections before placing apparatus into service.
5.3 Direct and Remote Handle Installation
1. Remove the hex bolt and washer from the valve stem.
2. Slide the handle over the valve stem, so that it is seated on top of the stop plate.
3. As needed, adjust the handle and stop plate orientation so that the valve is open or closed with the
correct handle position.
4. Apply Loctite #242 or equivalent to the hex bolt and reinstall the bolt and washer to secure the
handle. Torque the bolt to 40 ft-lbs. [As the screw is tightened, ensure that the valve retaining bracket
is aligned so that it slides into the grooves on the valve body.]
5. Open and close the valve several times to check for smooth operation.
