Product Overview
The Parker R10M35S4SN38 KU is a pilot-operated proportional pressure relief valve from Parker’s R10 series, engineered for precise, infinitely variable pressure control in demanding industrial hydraulic systems. Unlike fixed-setting relief valves, this unit modulates its pressure setting in direct proportion to an electrical command signal supplied to the integrated proportional solenoid, allowing the system pressure to be continuously ramped, held, or profiled under electronic control. The valve functions as a normally closed pressure-limiting element: when system pressure reaches the commanded setpoint, the pilot stage opens and hydraulically unbalances the main spool, diverting excess flow to tank and thereby capping circuit pressure. The “KU” designation identifies the proportional solenoid and control configuration, while the R10M frame size and 35 bar pressure range make it well suited to low-pressure pilot circuits, clamping and clamping-release loops, and pressure-regulated sub-circuits where smooth, repeatable pressure transitions are critical. As a proportional valve, it is intended for use with a Parker-compatible proportional amplifier card or a modern electronic control module capable of delivering a stable current output with dither.
