1PS SERIES SEQUENCE VALVEPILOT OPERATED1PS100SLIDING SPOOL TYPE1SEQUENCED (2)DRAIN (3)3INLET (1)42APPLICATIONPilot 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 downstreampressure is high or changes during operation. Bytaking the drain line directly to tank, back pressureeffects are negated.OPERATIONAs in the pilot operated relief valves, when the inletpressure exceeds the valve setting, the pilot sectionopens causing a flow across the main spool orificeunbalancing it and subsequently moving it backagainst a light spring opening up the inlet to the outlet.PRESSURE DROPPRESSURE-BAR400350300250200150100FLOW-US GPM0 10 20304060005000400030002000PRESSURE-PSIFEATURESMatch ground and honed hardened working parts givelong, trouble-free life.
