The 4WRL16V200M-3X/G24Z4/M valve belongs to the 4WRL Solenoid Valves series and is manufactured by Bosch Rexroth for hydraulic automation tasks that require proportional control of flow and pressure. Its nominal size 16 (NG16) matches circuits that use the corresponding port geometry, while a rated flow of 200 l/min allows the component to regulate medium-to-high hydraulic volumes. An actuating time of 40 ms from 0 to 100 percent at 100 bar delivers quick spool movement for dynamic machine cycles. The unit can remain energized continuously because the duty cycle is 100 percent. A maximum solenoid current of 2.7 A and a coil resistance of 2.5 Ω at 20 °C define how the electronic driver must be dimensioned. Electrical demand peaks at 40 VA, so power supply sizing is straightforward.
The valve withstands operating pressures up to 350 bar on ports p, a, and b, making it suitable for high-pressure manifolds, while return and drain ports t, x, and y are limited to 250 bar. The pilot stage only needs 10 bar to start shifting and accepts as much as 250 bar, ensuring reliable actuation over a wide pressure window, and its internal pilot valve passes 12 l/min to move the main spool. Installation uses the ISO 4401-07-06-0-94 interface, so it fits standard NG16 subplates without adaptation. An IP65 housing protects the electrical section against dust and water jets when the connector is properly sealed. Hysteresis remains at or below 0.1 percent, supporting accurate closed-loop positioning in servo-controlled axes. The model operates on a 24 V DC supply, harmonizing with common industrial control voltages.
