1PSC SERIES SEQUENCE VALVEWITH REVERSE FLOW - PILOT OPERATED1PSC100SLIDING SPOOL TYPE1SEQUENCED (2)DRAIN (3)INLET (1)43 2APPLICATIONPilot operated sequence valves are ideal for systemswhere flows vary or the sequencing pressure is high.They provide ordered sequencing of two or moreoperations as with clamp and drill circuits. They canalso be used as relief valves where the dowmstreampressure is high or changes during operation. Bytaking the drain line directly to tank, back pressureeffects are negated.SPECIFICATIONSFigures based on: Oil Temp = 40°C Viscosity = 40 cStRated FlowMax SettingCartridge Material150 litres/min (40 US GPM)350 bar (5000 psi)Working parts hardened and groundsteel. External surfaces electrolessnickel platedOPERATIONAs with the pilot operated relief valves, when the inletpressure exceeds the valve setting, the pilot sectionopens causing flow across the main spool orificeunbalancing it and subsequently moving it backagainst a light spring opening up the inlet to the oulet.The 1PSC100 has a check portion which allows freereverse flow.FEATURESMatch ground and honed hardened working partsgive long, trouble-free life. Consistent stableoperation providing low pressure rise due toincreasing flow. Cartridge construction givesmaximum flexibility in mounting.
