Directional control valve NG25


Connection ISO/Cetop 08 NG25
Design 4/3-way valve (without pilot valve)
Max. operating pressure P, A, B: max. 350 bar / T: max. 210 bar
Mounting 6 No. hex. socket head screw M12x50 12.9
Volumetric flow max. 650 l/min (note characteristic curves)


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.


The O-rings (NBR 70° Shore A) for the valve port can be ordered as spare part separately under the following article number: 4 pieces OR22.22-2.62 and 3 pieces OR9.13-2.62
