4WRL Solenoid Valves

The Bosch Rexroth 4WRL Solenoid Valves are servo solenoid valves designed for extremely high-response and high-precision control of flow direction and magnitude in demanding hydraulic applications. These are advanced, pilot-operated, two-stage valves that work using a solenoid on the first stage to shift the main spool, which features electrical position feedback (LVDT) for accurate control. Their primary function is to provide a flow rate that is directly and continuously proportional to the electrical input signal, making them suitable for position, velocity, and pressure control loops. Available with or without integrated electronics these valves offer high-dynamic performance, a fast response, and a high maximum operating pressure of 350 bar.
