Pressure Reducing Valves

Hydraulic Control Pressure Reducing Valves are used on the purpose of on/ off and regulation, utilizing the pressure of the working fluid flowing through itself as the source of actuating energy. The mechanical part acting as actuator is a diaphragm or a piston, having an effective area larger than the port of the valve. This larger actuator area difference produces bigger control forces than required to close the valve, stopping the flow to the zero-flow condition. The actuator pressure is adjusted by so called control pilots.
