A valve assembly comprising a valve having a housing and a valve element disposed in the housing and movable between closed and open positions, the valve element having a nut portion and a wing portion, the nut portion projecting out of the housing and having a cross-sectional configuration such that a tool may be applied for turning the valve element between the closed and open positions, the wing portion being movable between a first position when the valve element is in the closed position and a second position when the valve element is in the open position, the housing having a wing portion provided with an opening therein disposed in lockable relation with the valve element wing portion when the valve element wing portion is in its first position, a barrel lock removably mountable in registered openings of the wing portions when the valve element wing portion is in its first position whereby the valve element will be locked in the closed position, and a rigid member having first means cooperable with the nut portion for securing the rigid member to the valve element when the valve element securing portion is in the second position, and second securing means spaced from the first securing means cooperable with the housing securing portion and the barrel lock for locking the rigid member to the housing securing portion when the valve element securing portion is in the second position, whereby the valve element will be locked in the open position.

Valve assembly and locking means therefor

A valve assembly comprising a valve having a housing and a valve element disposed in the housing and movable between closed and open positions, the valve element having a wing portion provided with an opening therein movable between a first position when the valve element is in the closed position and a second position when the valve element is in the open position, the housing having a wing portion provided with an opening therein disposed in lockable relation with the valve element wing portion when the valve element wing portion is in its first position, a rigid spacer member disposable between the housing and valve element wing portions when the valve element wing portion is in its second position, a barrel lock removably mountable in registered openings of the wing portions when the valve element wing portion is in its first position whereby the valve element will be locked in the closed position, and the rigid spacer member having a hook portion cooperable with the opening in the valve element wing portion and an opening spaced from the hook portion and registrable with the opening in the housing wing portion for removably mounting the barrel lock in the registered openings when the valve element wing portion is in its second position whereby the valve element will be locked in the open position.
