The 4WRP10EA63S-1X/G24Z4/M-794 proportional valve is manufactured by Bosch Rexroth as part of the 4WRP Solenoid Valves series and is intended to regulate flow and pressure in hydraulic automation loops. It is built to nominal size 10 (NG10), so it fits common subplates of that rating without modification. The mounting interface follows ISO 4401-05-06-0-94, allowing direct interchange with other standardized components. When a 5 bar differential is applied across the metering notch the valve passes 63 l/min, covering medium-capacity actuator circuits. Working pressure on the P, A, and B ports reaches 315 bar, giving the unit headroom for high-pressure supply lines, while the L port is limited to 2 bar to protect the low-pressure drain. The T port withstands 250 bar, which supports circuits that maintain back pressure for controlled deceleration. Electrical power is provided at 24 V DC through a DIN 43650 / ISO 4400 connector with an M16×1.5 thread, offering quick disconnection during maintenance.
The coil resistance is 2.5 Ω at 20 °C, setting the initial energizing current and matching standard amplifier outputs, while the solenoid current is capped at 3.7 A to keep coil temperature within safe limits. Maximum power consumption stays under 60 VA, so control cabinets need only modest supply capacity. Dynamic behavior includes a 50 ms response to a full 100 percent command step and a 20 ms response when subjected to a 110 percent step, characteristics that support rapid position control of cylinders and motors. Hysteresis remains below 0.75 percent, minimizing steady-state deviation in proportional applications. An IP65 ingress rating shields the electrical and mechanical parts from dust and water jets encountered on industrial machinery. The assembled valve weighs 8.0 kg, adding stability to the manifold block without requiring extra mounting brackets.
