The 4WRVE16V120L-2X/G24K0/B5M valve belongs to the 4WRVE Solenoid Directional Control Valves series and is manufactured by Bosch Rexroth for closed-loop hydraulic automation. The unit fronts a standardized ISO 4401-07-07-0-05 mounting interface so it bolts directly onto subplates without extra adapters. At 10.4 kg, the housing resists vibration while remaining manageable during service. An IP65 enclosure keeps internal components protected from dust and water spray encountered in industrial lines. Electrical hookup is made through an 11P+PE multipole connector, and the electronics draw power from a 24 V DC supply. The command reference arrives as a ±10 V analog signal which is accepted by a 100 kΩ input impedance to avoid loading the controller. Electrical demand stays within 30 VA, aiding cabinet sizing. Inside the metering section the spool is ground for a linear flow characteristic so actuator velocity changes proportionally to the input. With a 10 bar pressure drop the nominal flow rate reaches 120 l/min, giving predictable sizing for cylinders and motors.
Flow reserves extend to a maximum of 450 l/min so the valve can pass temporary peaks without excessive losses. The pilot stage delivers 24 l/min, and a minimum pilot pressure of 10 bar is required to shift the main spool reliably. Working ports p, a, and b withstand 350 bar, while return and auxiliary ports t, x, and y are limited to 250 bar, enabling the same body to handle high-pressure supply yet protect downstream circuits. A measured response time of 15 ms from 0 to 100 percent stroke at 100 bar allows the device to react quickly in servo loops that demand tight position or force control. These hydraulic and dynamic figures, combined with the linear metering curve reviewed earlier, define the valve’s capability to modulate flow accurately across a broad operating range.
