ABSTRACT:
A disc orifice valve for providing a constant volume of fluid flowing through a high pressure fluid line is formed by a valve body having in-line inlet and outlet ports. Dual bores in the valve body transversely intersecting the fluid flow passageway between the inlet and outlet ports respectively receive multiple orifice discs for controlling the volume of fluid entering the valve and a poppet valve assembly controlled by a diaphragm fluid pressure balanced on its opposite sides maintaining the poppet valve in an open position in accordance with the volume of fluid at the inlet port and biased open by spring pressure.
