The 4WRA10E1-60-2X/G24N9K4/V proportional directional valve is built by Bosch Rexroth for the 4WRA Proportional Directional Valves series to regulate flow and direction in hydraulic automation circuits. It operates on a 24 V DC solenoid supply, and its coil connects through a DIN EN 175301-803 K4 plug for straightforward wiring. A nominal size of 10 fits medium-flow manifolds, and subplate mounting permits removal without disturbing pipe work. Compatibility with ISO 4401-05-04-0-05 porting patterns allows installation on standard CETOP 05 bases. The E1- spool configuration establishes progressive metering edges for controlled acceleration of actuators, while a concealed N9 manual override lets technicians shift the spool mechanically when electrical power is unavailable.
Mineral oil grades HL and HLP listed in DIN 51524 serve as the hydraulic medium, and FKM seals maintain leakage control with these fluids. The valve accommodates pressures to 315 bar at the P, A, and B ports, with the tank line limited to 210 bar for safe return flow. It delivers a rated flow of 60 l/min at a 10 bar differential yet can pass up to 75 l/min at full command signal. Closed-loop spool positioning holds hysteresis within 5 %, response sensitivity within 0.5 %, and inversion range within 1 %, enabling proportional control where small input changes must translate into repeatable flow variation.
