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.
