Pilot check valve is used to prevent falling in hydraulic line of press, lift to reverse the flow using remote pressure for working pilot plunger if necessary.

Pilot control regulator is a two-path control system. The main valve diaphragm responds quickly to downstream pressure changes, causing an immediate correction in the main valve plug position. The pilot diaphragm responds simultaneously, diverting some of the reduced inlet pressure to the other side of the main valve diaphragm to control the final positioning of the main valve plug.

Pilot Operated Pressure Reducing Valve comprises a main valve, pilot valve body, pilot diaphragm mounted on pilot valve body and pressure regulating spring. Pilot-operated pressure reducing valves reduce a high primary pressure at the inlet to a constant reduced pressure, allowing circuits with multiple pressure requirements to be operated using a single pump.

Pilot-operated regulator is a versatile device that can be used to advantage in many ways. These are higher in capacity and more accurate than standard self-operated regulators. It can maintain constant set outlet pressure even when inlet pressure fluctuations or variations in flow occur. With the proper selection of pilots, these regulators will accurately control temperature, pressure, or a combination of both. These are used when sensitive, accurate control is required.
