1PS SERIES SEQUENCE VALVEPILOT OPERATED (ISO CAVITY NUMBER: 7789-22-6-0-90)1PS60SLIDING SPOOL TYPE1SEQUENCED (2)DRAIN (3)3INLET (1)42APPLICATIONPilot operated models are best suited for higher flowswhich may vary widely to:1. Provide ordered or sequenced series of operationsas in a clamp and drill circuit.2. Serve as a relief valve where oil viscosity orrestrictions in the downstream line would causeexcessive back pressure. The separate springchamber drain makes the sequence valveinsensitive to this back pressure. Available with orwithout built-in reverse flow checks.FEATURESHardened steel working parts give long, trouble-free life.Selectively matched honed assemblies give accurateperformance.SPECIFICATIONSFigures based on: Oil Temp = 40°C Viscosity = 40 cStRated Flow60 litres/min (16 US GPM)OPERATIONAs in the pilot operated relief, when the setting of thevalve is exceeded the pilot section opens. This pilotflow causes a pressure imbalance opening the mainsection and allowing flow to a secondary circuit(sequenced line).Max SettingCartridge MaterialBody MaterialMounting Position350 bar (5000 psi)Working parts hardened and groundsteel.
