See full text

A control valve assembly includes a valve body having inlet and outlet ends, and an endless valve seat therebetween. A clapper disk is pivotably mounted within the valve body, and is pivotable between a sealingly closed position and an open position according to a pressure differential across the clapper disk. A U-shaped arm is rotatably supported in the valve body, and rotatable between a first position, wherein a bight of the U-shaped arm is positioned out of an operational range of movement of the clapper disk such that the clapper disk is freely movable between the open and closed positions thereof, and a second position, wherein the bight of the U-shaped arm engages and maintains the clapper disk in the sealingly closed position thereof. A selectively rotatable control arm operatively coupled with the U-shaped arm and utilized to move the U-shaped arm between the first and second positions thereof.
