Popis výrobku

Pokyny
The O-rings (NBR 90 Shore A) for the valve port can be ordered as spare part separately under the following article number: 4 pieces OR28.17-3.53N90 and 2 pieces OR13.94-2.62N90
Opis
These valves are actuated by a solenoid directional valve NG6 in leakage oil-reduced design (type HK DHE...P...) to be installed as a pilot valve.
Control is internal, but conversion to external is possible.
The minimum control pressure for correct function is 8 bar.
In the version with control pressure generator, an additional pressure drop is generated which ensures the minimum required control pressure for a correct switching function. The version with control pressure generator must be used if the pressure drop in the valve is below the minimum value of the control pressure.
Zvláštne charakteristiky
Further circuits and versions, volumetric flows and switching power limits are available on request
