ABSTRACT:
An apparatus is provided for a valve assembly comprising a valve body, a valve element, a shaft, an engagement stop, an actuator housing, a manual lockout, and a lock. The valve body includes an inlet port, an outlet port, and a flow passage extending therebetween. The valve element is disposed within the valve body flow passage, and is movable between a closed position and a full-open position. The shaft is coupled to the valve element and extends through the valve body. The engagement stop is coupled to, and extends radially from, the shaft. The actuator housing at least partially surrounds the shaft. The manual lockout is configured, upon receipt of a torque, to selectively engage and disengage the engagement stop. The lock is coupled to the actuator housing, and is movable between a lock position and an unlock position.
