The 4WRVE16V120M-2X/G24K0/B5M valve is manufactured by Bosch Rexroth as part of the 4WRVE Solenoid Directional Control Valves series. It directs hydraulic flow in automated machinery where precise proportional control is required. The valve operates on a nominal supply of 24 V DC to energize its solenoids, and it accepts a ±10 V command input with an input impedance of 100 kΩ so that it can interface with common servo amplifiers. The unit has a nominal size of NG16 and provides a nominal flow of 120 l/min at a differential pressure of 10 bar, shaped by a progressive flow characteristic coded M for smooth speed control of actuators. Its working ports p, a, and b tolerate up to 350 bar, while the t, x, and y ports are rated for 250 bar. The body mates to manifolds through the ISO 4401-07-07-0-05 mounting interface, and an IP65 enclosure protects the electrical parts against dust and water spray.
For dynamic circuits, the valve delivers up to 450 l/min of total flow when fully open, while the pilot stage alone carries 24 l/min to modulate the main spool. Stable control is maintained as long as the control oil supply is at least 10 bar. Internal leakage is limited to 600 cm³/min on the main stage and 300 cm³/min on the pilot stage when measured at 100 bar, supporting energy-efficient closed systems. The assembly weighs 10.4 kg, which must be supported by the manifold or sub-plate. These features allow the valve to serve in high-duty hydraulic automation where proportional positioning and repeatable flow regulation are required.
