The 4WRL16V200M-3X/G24K0/M-750 valve belongs to the 4WRL Solenoid Valves series produced by Bosch Rexroth and is applied to regulate flow and direction in hydraulic automation systems. It comes in size NG16, giving passage dimensions suited to medium-flow manifolds. A V 4/3-way spool provides three working positions so cylinders can extend, retract, or be blocked centrally. The M progressive flow characteristic delivers fine metering at small spool shifts and higher flow as the command increases. Nominal flow is rated at 200 l/min with a 10 bar differential, supporting rapid actuator movement. Ports P, A, and B tolerate pressures up to 350 bar, while ports T, X, and Y are limited to 250 bar to protect return and pilot lines. External pilot oil supplied at port X isolates the control stage from main line transients. The mounting interface follows ISO 4401-07-06-0-94, allowing installation on standardized subplates without adapter blocks.
The solenoid is energized from a 24 V DC supply so control electronics can be powered directly from common machine buses. Coil resistance is 2.5 Ω at 20 °C, establishing the base current for proportional drive circuits. A maximum solenoid current of 2.7 A permits full spool travel without exceeding winding limits, and total power consumption is capped at 40 VA for thermal management. The integrated position transducer returns a 0 to +10 V signal, enabling closed-loop control of spool position. Electrical connection is made through a DIN 43650/ISO 4400 (2P+PE) plug that supports quick replacement. An IP65 degree of protection keeps dust and water jets from affecting internal parts when the connector gasket is fitted correctly. NBR seals are used to contain mineral hydraulic oil and maintain leak-tight operation over the service life.
