Description
These valves are actuated by a leak oil-reduced, solenoid-operated directional control valve size 6 set up as a pilot valve (type HK DHE *P*).
Control is internal, but conversion to external is possible.
The minimum control pressure for correct functioning is 8 bar.
With the version with the control pressure generator, an additional pressure drop occurs, which ensures the minimum required control pressure for correct functioning. The version with the control pressure generator must be used if the pressure drop in the valve is below the minimum control pressure.
