Direct Operated Proportional Directional Control Valve - Series D1FP / D3FP Description

The new direct operated DFplus® control valves D1FP and D3FP with EtherCAT interface show extremely high dynamics combined with maximum flow. They are used for highest accuracy in positioning of hydraulic axis and controlling of pressure and velocity. So, it is the preferred choice for meeting with above features. Driven by the patented VCD® actuator, the D1FP / D3FP reach the frequency response of real servo valves. At power-down the spool moves in a defined position. All common input signals are available.
