Parameter Description / Value Notes / Explanation Product Line Eaton DARV Pilot-operated pressure reducing valve series. Port Size W (M22x1.5 / SAE 3/4") This is a threaded port size. Valve Size 20 Nominal size 20, corresponding to a specific flow capacity. Pressure Adjustment Range 10 - 50 bar (145 - 725 psi) The secondary pressure can be set anywhere within this range. Maximum Inlet Pressure (P1) 315 bar (4,570 psi) The maximum pressure allowed at the primary/inlet port. Maximum Flow Rate Approx. 150 L/min (40 US gpm) Note: Actual performance depends on pressure conditions. Consult the performance curve in the datasheet for exact values. Drain Connection (Y) Internal Drain The pilot control oil is drained internally back to the tank port (T). This simplifies piping. Seal Material K (Standard Nitrile Rubber / NBR) Compatible with standard mineral-based hydraulic oils. Mounting In-line threaded connection Weight Approx. 2.5 kg (5.5 lbs)
