1PA SERIES PRESSURE REDUCING VALVEPILOT OPERATED1PA200SLIDING SPOOL TYPE2INLET (2)DRAIN (3)3REG (1)15APPLICATIONTo maintain a constant downstream pressure lowerthan the inlet pressure. Ideal for use in two pressuresystems or to protect low pressure actuators such asbrake cylinders. Note: where reverse flow is required,see 1PAA95, page number 5-161.OPERATIONThis valve is normally open, allowing oil from the inletto pass through to the regulated port of the cartridge.When the regulated pressure reaches the valvesetting, the pilot section opens causing a pressureimbalance across the main spool which moves,throttling the inlet flow, preventing any further pressurerise in the regulated line.REGULATED PRESSURE400FLOW-US GPM0 10 20 304050606000FEATURESInternal parts hardened, match ground and honed to givelong, trouble-free life. Pilot style design allows for highflows and accurate performance.SPECIFICATIONSFigures based on: Oil Temp = 40°C Viscosity = 40 cStRated FlowMax SettingBody MaterialMounting Position200 litres/min (52 US GPM)Inlet: 350 bar (5000 psi)Reg: 30-350 bar (435-5000 psi)Max Differential 210 bar (3000 psi) between 1 and 2Cartridge MaterialCavity NumberWorking parts hardened and groundsteel.
