On removal of this pressure, inlet closesopening outlet to tank. Ideal for use in braking systemswhere a pressure is required in the main systembefore the brake is removed.SPECIFICATIONSFigures based on: Oil Temp = 40°C Viscosity = 40 cStRated FlowMax WorkingPressure30 litres/min (8 US GPM)350 bar (5000 psi)OPERATIONWhen pressure in the inlet exceeds the set pressure,flow is allowed from inlet to outlet closing off the tankline. When the inlet pressure is removed, the spoolreturns to its normal position, opening the outlet port totank and closing the inlet port.FEATURESPilot PressureCartridge MaterialBody MaterialMounting Position10 to 100 bar (145 to 1450 psi)Max pilot pressure 210 barAll working parts hardened andground steel.
