The 4WRP10EA63S-1X/G24K4/M-851 valve belongs to the 4WRP Solenoid Valves series manufactured by Bosch Rexroth for closed-loop hydraulic automation. It attaches to manifolds through the ISO 4401-05-06-0-94 (NG10) interface so integration with standard subplates is straightforward. The metering section delivers a nominal flow of 63 l/min at a 5 bar pressure drop per notch, allowing medium capacity circuit control. A progressive flow characteristic provides fine resolution near the spool center position and higher flow toward the end stroke. Continuous service is permitted up to 315 bar on ports P, A, and B, while the tank port withstands 250 bar. The solenoid draws a maximum current of 3.7 A from a 24 V DC supply to shift the spool. Electrical input does not exceed 60 VA, keeping heat generation moderate during long duty cycles. These parameters support accurate flow regulation in servo pressure loops.
Dynamic response is defined by a 50 ms maximum rise time for a full 100 percent command step and 20 ms when the command overshoots to 110 percent. Spool positioning repeatability is supported by a hysteresis not greater than 0.75 percent, which helps maintain stable actuator speed. Internal leakage through one metering edge at 100 bar is limited to 80 cm³ per minute to preserve volumetric efficiency. The housing carries an IP65 degree of protection so operations can continue in dusty or wet machine areas if proper mating connectors are used. All dynamic seals are made of NBR to resist mineral-oil-based hydraulic fluids. Required oil cleanliness is ISO 4406 class 18/16/13 or better to avoid erosion and sticking of the precision spool. The complete assembly weighs 8.0 kg, so the mounting surface must support this load without distortion.
