LE402 SERIES 2/2 Spool Logic ElementUp to 350 Litres/min (95 US GPM) • 350 bar (5000 PSI)LE402T (2)12P (1)13APPLICATIONFor use in conjunction with pilot valves to allow control oflarger flows. When used with a 2/2 solenoid valve thecombination allows control of flows to 350 lts/min (95US gpm). With a pilot relief valve or a proportional reliefvalve the element becomes a high flow pilot style relief.With a needle valve an on/off function is achieved.The outlet flow would normally go to tank because backpressure will act on the pilot cartridge to increase theswitching pressure.OPERATIONWith a pilot valve fitted the valve will only open when flowis allowed across the orifice in the middle of the spool.Flow passing across this orifice will cause there to be apressure difference that acts over the full area of thespool to move it back against the spring that biases itclosed. By controlling the pressure in the spring chamberyou can control the pressure at which the valveopens.FEATURESVery versatile in its application using hardened andground spool and sleeve giving minimal internalleakage and long life.High flow and pressure rating increases the variety ofapplications into which it can fit.CONTROL OPTIONS1DR2-P-**S Page 2.151PDR2 Page 11/2-151S207N Page 11-17112CN20-S Page 8-111SPECIFICATIONSFigures based on: Oil Temp = 40°C Viscosity = 40 cStRated FlowMax SettingCartridge MaterialBody MaterialMounting PositionCavity NumberTorque Cartridgeinto CavityWeight350 litres/min (95 US GPM)Max Load InducedP1: 350 bar (5000 psi)P2: 210 bar (3000 psi)Working parts hardened and groundsteel.
