ABSTRACT:
A valve assembly having a body assembly mounted to a vessel opening. The body assembly includes a valve seat and a valve throughbore. A valve disk co-acts with the valve seat for opening and closing the valve throughbore. A receiver member having a receiver portion extends from the valve disk. A lock member is mounted in the body assembly and is capable of being received in the receiver portion to lock the valve disk in a locked position restricting movement of the valve disk relative to the valve seat. A valve operator assembly is in cooperative relationship with the valve disk and is capable of forcing the valve disk away from the valve seat to open the valve throughbore when the lock member is in an unlocked position. An interlock lug is attached to the valve operator assembly and prevents movement of the valve operator assembly when the lock member is in the locked position.
