A.  Factory Mounted Motor Operators

Factory mounted operators should not be removed from the valve prior to installation. The torque switches which have been set prior to hydro testing and should not require field adjustment.

B.  Mounting of CLAMPSEAL® valve to Motor Operator in Field

This procedure applies where a valve is being mated with an existing operator:

1. Install valve per procedure in the Installation Section of this manual.
2. Yoke arms should be oriented in the position shown in Figure B.
3. Slide the motor operator over the valve stem adapter.
4. Coat mounting bolts with a nickel anti-seize lubricant. Bolt the operator to the valve yoke flange. Torque bolts to values for SA-193-B7 fasteners (23 ft-lbs for the 5/16" bolt normally found on small operators).
5. Reset operator limitswitches. The "open" limitswitch is set to de-energize the actuator 1/4 turn before the valve reaches backseat. The "close" limitswitch is set to insure that the actuator does not de-energize until the torque switch opens. Torque switch setting should not need adjustment.

C.  STORAGE

 All valves are treated with rust-preventative, capped, and sealed in polyethylene bags to repel moisture. Valves should be stored in a weatherproof enclosure on pallets or shelving to isolate valve from moisture.

D.  HANDLING

CLAMPSEAL® valves are extremely rugged and damaging them during handling is difficult. However, some care must be taken in handling. Do not drop them. Use yoke arm or body to lift valve. Do not lift by valve handle.

E.  TORQUE TOOLS
