Fine adjustment of the pilot pressurepermits the optimum setting to be made in differingoperating systems.Both the pilot and the relief sections are unaffected bybackpressure, enabling the service line relief’s tooperate normally. In the event of hose failure, thecontrol will be passed from the main spool to the“BoomLoc” valve, maintaining control of the cylinder.Regardless of the load the pilot pressure requirementremains constant as the valve is unaffected by loadinduced pressure, the poppet being fully balanced withzero differential area.FEATURESThis is a compact design with good dirt tolerance.Hardened poppets and seats provide excellent loadholding characteristics with all the advantages of thecartridge insert.SPECIFICATIONSFigures based on: Oil Temp = 40°C Viscosity = 40 cStRated FlowMax SettingCartridge MaterialBody MaterialMounting PositionWeightSeal Kit NumberRecommendedFiltration LevelOperating TempLeakageNominal ViscosityRange30 litres/min (8 US GPM)350 bar (5000 psi)Working parts hardened and groundsteel.
