ABSTRACT:
A flow control valve is disclosed comprising a valve housing defining a through flow passage, a valve member supported in the housing for pivotal movement with respect to the housing between an open position in which flow through the passage is enabled and a closed position wherein flow through the passage is blocked, and an actuator for moving the valve member between said position. A linkage transmits actuating force from the actuator to the valve member and, a force limiting device limits the actuating force transmitted to the valve member when the valve member is in its closed position.
