Hydraulic Pressure Relief Valve Polyhydron DPRH 06T 350

Pressure relief valves are used in hydraulic systems to limit the system pressure to a specific set level. If this set level is reached, the pressure relief valve responds and feeds the excess flow from the system back to the tank. Note: the pressure relief valve is a normally closed pressure control valve.The function of a relief valve is to divert as much of the system flow back to tank as needed in order to limit the pressure. A relief valve does not remove system pressure (as an unloading valve does). It prevents pressure from rising past a determined set point.
