Directional control valves ND 4
max. operating pressure 500 bar
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.
