Directional valves, manual/mechanic operation, ND 4

The directional valve which is operated manually by rotary handle is based

on an almost leak oil-free poppet valve. The switch position of the valve is

regulated in the operating mechanism with angle lever and tappet or the 

switch position of with a sensing roller lever. 


Versions are available as 2/2- and 3/2 directional valve. With a combination

of several valves on a valve plate also 3/3-, 4/3- and 4/2 directional valves 

can be realized.


In the case that directional valves are to be inserted into piping systems,

connection blocks can be flanged on. By that, the application range of this

series can be expanded by functions like for example pressure control 

valve or bypass check valve. A combination of several parallel-switched

valves is possible.


Single-acting valve combinations are especially suited for multiple 

clamping systems for the operation of individual clamping spots.
