1UPS SERIES SEQUENCE VALVEUNLOADING - PILOT OPERATED1UPS100SLIDING SPOOL TYPE1SEQUENCED (2)DRAIN (3)3INLET (1)42APPLICATIONAn off-loading sequence valve opens fully to pass flowto a secondary cicuit when the valve pressure settingis reached. This allows flow to the secondary circuitwith a minimal pressure drop.FEATURESHardened steel working parts give long, trouble-free life.Selectively matched honed assemblies give accurateperformance.OPERATIONInlet pressure acts on the pilot section of the valve.When the valve setting is reached, the pilot sectionopens and pilot flow causes the spool to move backuncovering the radial vent port. The main section thenopens fully with pilot flow passing through the vent.The valve remains open until flow to the sequencedport ceases and inlet pressure drops to zero.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.
