The 4WRL16X200M-3X/G24Z4/M-811 valve belongs to the 4WRL Solenoid Valves series and is built by Bosch Rexroth for proportional control duties in hydraulic automation systems. It operates from a 24 V DC supply and draws a maximum solenoid current of 2.7 A, with the coil showing a resistance of 2.5 Ω at 20 °C to match common driver cards. Power consumption does not exceed 40 VA during full stroke, and continuous use is supported by a 100 % duty cycle. The valve achieves a full-scale response in 40 ms when the metering spool is commanded from 0 to 100 % at 100 bar, while hysteresis remains limited to 0.1 % to maintain repeatable flow settings. An IP65 degree of protection shields the enclosure against dust ingress and low-pressure water jets, allowing installation in typical industrial environments.
Hydraulic capacity is defined by a rated flow of 200 l/min through ports P to A or P to B at the specified pressure drop, with a permissible peak flow of 450 l/min for transient demands. The mounting pattern follows ISO 4401-07-06-0-94 so the valve can be fitted to standardized subplates without modification. Working pressure on ports P, A, and B may reach 350 bar, whereas ports T, X, and Y are limited to 250 bar. Pilot operation requires a minimum pilot pressure of 10 bar and tolerates up to 250 bar, and the internal pilot stage passes 12 l/min to actuate the main spool. These limits outline safe operating windows for manifold designers and ensure compatibility with high-pressure circuits.
