Parker R4V03-5351011G0QA125

The Parker R4V03-5351011G0QA125 is a high-performance, pilot-operated proportional directional control valve from the R4V series. Designed for NG10 (D05) subplate mounting, it offers precise control of flow direction and rate in hydraulic systems. This model features a closed center spool (type 535) where port P is blocked and ports A and B are connected to tank (T) in the neutral position. It is equipped with onboard electronics (OBE) for enhanced control, accepting a ±10V command signal and providing LVDT position feedback. The valve is spring-centered and utilizes NBR seals, suitable for a wide range of industrial applications requiring accurate and responsive hydraulic control.
