Opis proizvoda

Napomene
The O-rings (NBR 90 Shore A) for the valve connecting surface can be separately ordered as replacement parts using the following item number: 4 pieces OR22.23-2.62N90 and 2 pieces OR10.82-1.78N90
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.
Leakage oil is discharged externally.
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.
Napomena o narudžbi
Further circuits and versions, volumetric flows and switching power limits are available on request
