Rexroth proportional directional valve 4WRKE is a high-performance closed-loop proportional directional valve. Through the pilot proportional valve to control the movement of the main valve core, a high-precision electric position feedback device and a built-in amplifier are installed on the main valve body for the valve itself. The closed-loop control allows precise proportional control of the flow direction and flow.
Rexroth 4WRKE has a relatively good frequency response characteristics (frequency response up to tens of Hertz), and is particularly suitable for occasions where there is a high requirement for pre-buffering in the device's constant acceleration/deceleration shifting motion. Compared to the servo valve, the main stage and the pilot stage of this type of valve adopt the structure of the slide valve, which is not sensitive to the cleanness of the oil and the price is also low. The dead zone, gain, vibration and offset of the valve have been adjusted and packaged in the factory according to the standard. Therefore, it has good maintainability, convenient disassembly and installation, and no adjustment after installation. It is a kind of high-performance ratio that is ready to use. Valves can be used in place of servo valves in some applications to control the opening, stopping, and direction of fluid flow.
