KGC-MC METAL CUTTING KNIFE GATE VALVES
Replacing the Clip
8. Thread the clip into the pneumatic actuator's piston rod up to the jam nut but also ensure that the clip
opening lines up to the gate.
9. Extend the actuator to the gate, align the clip and gate holes and install the shoulder bolts. Tighten
the nuts onto the shoulder bolts and tighten the jam nut.
10. Retract the actuator and ensure the gate is retracted just out of the flow path. If the gate is in the flow
path, the shoulder bolts will have to be removed and the clip will have to be adjusted by threading it
further onto the piston rod. Reattach the clip to the gate following the steps above.
