Valve

A locking assembly for locking a multi-sided nut-like member in a desired communicating relationship with a valve body. The locking assembly includes a lock plate having a planar body portion with a locking opening defined by a plurality of sides oriented relative to each other in a closed, star-like configuration. The locking opening is adapted to be closely received over and communicate with the sides of an associated nut-like member. The body portion also includes an arcuate mounting slot spaced from the locking opening and which is adapted to receive a lock plate mounting fastener therethrough. A continuous side wall or skirt portion depends from the periphery of the body portion and serves to space the body portion from the surface of an associated valve body. Preferably, a lock plate adapter is also provided. The adapter includes a body member having a through opening which is received over a section of the associated nut-like member, and a securing member cooperable with the lock plate mounting slot. The lock plate adapter also includes a mounting portion adapted for disposition in contacting relation with the associated valve body.

A dual position handle and cam stop assembly is provided which is adapted for limiting rotational movement of an associated valve sealing element such as a ball for a ball valve. However, the assembly is applicable to other types of valves such as butterfly and plug valves. The assembly comprises a cam disc and a valve handle having associated first and second handle stop and direction indicators. The indicators are disposed relative to the cam disc for engagement against the disc at first and second handle stop limit locations, respectively. The locations are selectively positionable by rotation of the cam disc while maintaining a constant relative angular spacing for limiting the rotational movement of the valve handle to the constant relative angular spacing. The cam disc has a cardioid-like contour about its peripheral wall for a constant angular displacement of the stop limit locations per a unit degree of cam rotation. The handle stop and direction indicators preferably comprise a symmetrical flat-faced cam follower.

A ball valve is disclosed having an improved seat ring particularly adapted for sealing a ball member in an end-loaded or top-loaded valve body. The ball is mounted for selective rotation and limited axial movement in a valve body passageway. The seat rings are disposed on diametrically opposite sides of the ball about valve inlet and outlet openings. Frusto-conical disc springs interposed between each seat ring and an associated valve body shoulder urge the seat rings into engagement with the ball. A rigid reinforcing ring is disposed intermediate of the flexible seat ring for integral movement with the seat ring and for reinforcing the seat ring against collapse under pressure. The reinforcing ring is received in an annular channel about the periphery of the seat ring and preferably comprises a split metal ring in a stressed and expanded condition.
