1HSH20 HOT OIL SHUTTLE VALVE1HSH201 3OUTLET (2) INLET (3)INLET (1)2APPLICATIONThis valve provides hot oil exhaust in a closed loophydrostatic system. The high pressure line causes thevalve to open the low pressure line to tank through aback pressure relief valve, thus purging the system ofextra oil supplied by the charge pump.FEATURESCompact design with high pressure rating and lowpressure drop characteristics. Hardened and matchground working parts keep cross port leakage to aminimum.13OPERATIONInlet (1) and inlet (3) are fed by the pressure lines of aclose loop hydraulic system. As soon as pressurerises in either line, the spool which is internally pilotedopens the lower pressure side to tank through a reliefvalve. This allows the charge pump flow to beexhausted to tank after the oil has done its work, hencethe title ‘hot oil shuttle’. If the system is reversed, thespool switches in the opposite direction, maintaininghot oil exhaust.PRESSURE DROP100 1 2FLOW-US GPM3 45120SPECIFICATIONSFigures based on: Oil Temp = 40°C Viscosity = 40 cStMax WorkingPressureRated PurgeOil FlowBody MaterialMounting PositionCavity NumberWeight350 bar (5000 psi)20 litres/min (5 US GPM)Standard aluminium (up to 210 bar*)Add suffix ‘377’ for steel optionLine mountedCVB-22-06-0 (See Section 17)1HSH201HSH250.14 kg (0.3 lbs)1.0 kg (2.2 lbs)8Seal Kit NumberSK632 (Nitrile)SK632V (Viton)PRESSURE-BAR643-21-29060PRESSURE-PSIRecommendedFiltration LevelOperating TempBS5540/4 Class 18/13(25 micron nominal)-20°C to +90°C230Leakage90 millilitres/min nominal05 10FLOW LITRES/MINIntegrated Hydraulics Ltd15200Nominal ViscosityRange5 to 500 cSt*For applications above 210 bar please consult our technical department or use the steel body option.Integrated Hydraulics IncCollins Road, Heathcote Ind.
