4WRVE16V200M-2X/G24EK0/B5M

The 4WRVE16V200M-2X/G24EK0/B5M valve belongs to the 4WRVE Solenoid Directional Control Valves series and is produced by Bosch Rexroth. It modulates hydraulic flow to actuators in closed-loop automation circuits, allowing electronic command signals to translate into proportional spool movement. The unit mounts on a subplate that follows the ISO 4401-07-07-0-05 pattern so it can drop into standardized manifolds without machining. Control oil for the x channel is tapped internally, while the y channel receives an external pilot feed; this arrangement lets designers balance pilot stability against system cleanliness. The solenoid coils are energized by a 24 V DC supply which simplifies wiring with common control cabinets. A ±10 V input signal drives the integral electronics, and the high input resistance of 100 kΩ minimizes load on upstream controllers. An 11P+PE multi-pin connector carries power, command, and feedback lines while providing a dedicated protective earth. The housing meets IP65, granting full dust protection and tolerance to low-pressure water jets during wash-down. All dynamic seals are molded from NBR, making the valve compatible with standard mineral-based hydraulic fluids.

The metering section passes a nominal 200 l/min at a 10 bar differential, supporting medium-size actuator groups, yet it can handle up to 450 l/min when pressure drop is less critical. Flow follows characteristic curve M, giving a linear relationship between input voltage and spool opening for predictable tuning in servo loops. The pilot stage itself passes 24 l/min so the main spool can shift rapidly without cavitation. At least 10 bar of pilot pressure is required to overcome spring forces and ensure stable modulation. Main pressure ports p, a, and b are rated for 350 bar, while the tank and pilot return ports t, x, and y can be loaded to 250 bar, allowing the valve to work in high-pressure circuits without overstressing the body. Overall mass is 10.4 kg, so a single technician can install the assembly without lifting aids. These capacities equip the valve to direct fluid precisely in presses, injection machines, and other hydraulic equipment that rely on exact proportional control.
