    Description
    C 2.320 Directional Control Valves ND 4

    Application
    The directly operated directional control valves are used to control hydraulic elements when a power supply is not possible or reasonable.
    These directional control valves can directly control hydraulic consumers or be used as pilot valves for hydraulically-operated switching devices.
    The closed directions of flow are hermetically tight. The switching operation is smooth and shock-free. A strainer insert in the pressure port protects the valve seats from coarse impurities.

    Technical data
