ABSTRACT:
A control valve assembly to be assembled with a discharge nozzle of a sandblasting abrasive cleaning system or the like, comprising a valve housing to be connected at an inlet end to a supply conduit having a lower valve chamber and a well formation providing a lateral compartment communicating with the valve chamber, a circular valve seat at the discharge end of the valve chamber providing a beveled seating surface, and a pivot valve member supported for movement into and from the valve chamber having a generally cylindrical valve head and beveled surface to conform to and seat tightly against the seating surface and having an elongated stem portion extending in inclined relation from the valve head. A wheel controlled operating shaft is journaled in the well formation having a first linkage yoke member thereon connected to the valve member and a second linkage member coactive with the first linkage yoke member to tilt the valve member while concurrently moving it arcuately about the shaft upon shaft rotation to retract the valve member substantially fully into the lateral well formation to an open position disposing the stem portion substantially parallel to the longitudinal center axis of the valve chamber and to advance the valve member therefrom to closed portion.
