Shaw, D F; Lietz, A A

A sliding plate valve is described comprising: a valve body with a longitudinal flow passage therethrough; an opening in the side of the valve body; a horizontally disposed valve bonnet covering the opening in the valve body; an orifice plate extending from the bonnet into the flow passage of the valve body and transverse to the longitudinal flow passage; and a reciprocally removable inclined plate positioned for bearing on the seating surface of the orifice plate when the valve is closed. The orifice plate, the sliding plate and the inclined surface of the guide means are each inclined at an angle variably selected to provide a predetermined seating force between the orifice plate seating surface and the sliding plate which is a function of the weight of the sliding plate and the angle of each of the orifice plate. The sliding plate and the supporting surface of the guide means minimize the magnitude of the weight of the sliding plate carried by the guide means.
