ABSTRACT:
A valve employed in applications where the valve is rapidly cyclically opened and closed over extended periods of time is constructed in a manner such that the impact between a rapidly moving metal valve head and metal valve seat at valve closure is minimized to reduce noise and wear. The valve head engaging element of the valve seat may take the form of a frusto conical belleville washer located with its concave side resting on a flat planar wall surface in the valve housing or a flat washer bridging a frusto conical wall surface in the housing. Fluid filling the recess between the opposed surfaces of the washer and housing wall is expressed from the recess as the frusto conical washer is axially compressed against the wall by the closing valve head to further cushion or damp the resiliently resisted compression of the washer.
