Maintenance

  1. Tightening the seal between the valve and the actuator:

Remove the four bolts underneath the actuator. Separate the actuator from the valve.

Tighten the nut on the top of the valve body.

Place the actuator back on the valve and screw everything back into place.

  1. Tightening the seals between the valve and the inlet/outlet ports.

Remove the torque bolts and check for any debris or damage to the gaskets.

Use a torque wrench or other consistent method of tightening the torque bolts to reconnect the inlet and outlet ports.
