HydraForce UP10-40A-0-N-70-30 Pilot Unloading Valve

The HydraForce UP10-40A-0-N-70-30 is a screw-in, cartridge-style, remote sequence, pilot-operated unloading valve designed for accumulator-type hydraulic systems. In its steady state, the valve blocks flow from port 2 to port 3. It features optional fixed unload/reload pressure ratios; this specific configuration is calibrated to a 70 percent unload ratio and a 30 percent reload ratio. The valve fits the standard HydraForce UC10 (SAE 10, 7/8-14 UNF) cavity. Maximum operating pressure is 350 bar (5000 psi) with a maximum flow capacity of 40 L/min (10.5 GPM). The valve utilizes Nitrile (Buna-N) seals designated by the 'N' code. The '0' designation indicates standard pilot operation without integrated solenoid coil. Construction materials include hardened steel spool and cartridge body with zinc-nickel plating for corrosion resistance.
