Directional Control Valve
A directional control valve is used to change, open or close the flow direction of a medium in a hydraulic or pneumatic system. For this purpose, compressed air or a hydraulic fluid is normally used as the fluid in pneumatic actuators. The valves differ in terms of the design of their control element, the number of switching positions and flow paths as well as in the type of actuation: There are mechanically operated directional control valves, pneumatically or electrically operated directional control valves.
Function of directional control valves
Compact pneumatic valve for high flow rates.
Compact universal valve
Pneumatically actuated
High flow rate relative to its size
In-line valves can be used as individual valves or manifold valves
Can be combined on manifold rail with electric individual valves
