1DS SERIES SEQUENCE VALVEDIRECT ACTING (ISO CAVITY NUMBER: 7789-22-6-0-90)1DS60SLIDING SPOOL TYPE1SEQUENCE (2)DRAIN (3)3INLET (1)42APPLICATIONDirect acting sequence valves are ideal for diverting oilto a second circuit at a predetermined pressure as inclamp and drill circuits, or as a relief where the backpressure varies. By taking the drain line directly to tank,back pressure effects are negated.OPERATIONAs with the direct acting relief valves, when the pressureexceeds the spring force, the spool moves back,opening the inlet to outlet.FEATURESStable, quiet operation. Cartridge construction givesmaximum flexibility in mounting. Offering good repeatabilityand reseat.SPECIFICATIONSFigures based on: Oil Temp = 40°C Viscosity = 40 cStRated FlowMax SettingCartridge Material60 litres/min (16 US GPM)40 bar (580 psi)Working parts hardened and groundsteel.
