An apparatus is provided for a valve assembly comprising a valve body, a valve element, an actuator housing, an actuator, an unlocked storage opening, a locked storage opening, and a lock. The valve body has an inlet port, an outlet port, and a flow passage therebetween. The valve element is movably disposed within the valve body flow passage. The actuator is disposed within the actuator housing, coupled to the valve element, and operable to move the valve. The unlocked and locked storage openings are formed in the actuator housing. The lock is selectively insertable into, and movable between, the unlocked and locked storage openings. When in the unlocked storage opening, the lock does not engage the actuator, and valve movement is thereby allowed. When in the locked storage opening, the lock engages at least a portion of the actuator, thereby at least inhibiting valve movement.
