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.FEATURESCartridge design enabling speedy servicing whenmounted in a body or in a composite manifold.SPECIFICATIONSFigures based on: Oil Temp = 40°C Viscosity = 40 cStOPERATIONWhen 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.PRESSURE DROPRated FlowMax PressurePilot PressureCartridge MaterialBody MaterialMounting Position20 litres/min (5 US GPM)350 bar (5000 psi)15 to 140 bar (217 to 200 psi)All working parts hardened andground steel.
