Function and configuration

The direct operated control valve 4WRMCEH10...L1X shows extremely high dynamics combined with high flow. It is the preferred choice for highest accuracy in positioning of hydraulic axis and controlling of pressure and velocity. Driven by the voice coil motor actuator the valve reaches the frequency response of real servovalves. At power-down the spool moves in a defined position. All common input signals are available.

Notes:

1) For applications with Pr>35 bar, the port Y has to be connected and the plug in the port Y has to be removed.

2) Flow rate for different Ap per control edge:Q=Qwom

3) Measured with load 100 bar pressure drop/two control edges.
