4WRKE Directional Valves

The Bosch Rexroth 4WRKE Directional Valves are pilot-operated proportional directional valves designed for high-precision, continuous control of hydraulic fluid flow and direction. They are advanced, two-stage units that work by using a pilot valve to precisely shift the main control spool, which features electrical position feedback to the control electronics. Their critical function is to provide extremely accurate and high-dynamic control of actuators, as the integrated electronics (OBE) allow for a direct, proportional relationship between the electrical input signal and the resulting flow rate. Rated for a high maximum operating pressure of 350 bar and flows up to 3000 l/min, the 4WRKE series delivers powerful, fast-response performance in sophisticated hydraulic applications.
