PR Series Hydraulic Pressure Relief Valves act as a part of the control systems in hydraulic systems. When the system gets over loaded, the Pressure Relief Valve opens and flow comes from the pump is leaded directly into the hydraulic reservoir.
The pressure in the hydraulic system remains on the value determined by the spring on the Pressure Relief Valve.
PR Series Hydraulic Pressure Relief Valves are used to limit the pressure inside of the hydraulic circuits.
