2-36" KGC-BD BI-DIRECTIONAL KNIFE GATE VALVES WITH GUIDES

Operation

The gate in the valve is positioned by the valve actuator. The actuator moves the gate over the valve

port in the closed position, and withdraws the gate from the port in the open position. Refer to the

Actuator Instructions for adjustment and maintenance requirements for the actuator.

The valve does not require lubrication. If applicable, ensure that valve threaded stems are maintained

with proper lubrication. Refer to the Actuator Instructions for lubrication requirements for the actuator.

The gate packing is contained and compressed by the packing gland. See Figure 1 for component

identification.

Note: The packing gland is slightly loosened prior to shipping. This is done to increase the life of the

packing during extended storage.

If packing leaks, tighten the adjustment nuts on top of the packing gland. Tighten the nuts evenly and

gently just enough to stop the leak. Over tightening will cause excessive operating forces, and will

decrease the life of the packing.
