Theycan also be used as relief valves where the downstreampressure is high or changes during operation.By taking the drain line directly to tank, back pressureeffects are negated.SPECIFICATIONSFigures based on: Oil Temp = 40°C Viscosity = 40 cStRated FlowMax SettingCartridge Material30 litres/min (8 US GPM)350 bar (5000 psi)Working parts hardened and groundsteel.
