Product description

Notes
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
Description
L'azionamento di queste valvole avviene mediante una valvola direzionale magnetica GN6 nell'esecuzione con poche perdite d'olio (tipo HK DHE...P...) da montare come valvola pilota.
Il comando è eseguito internamente, è possibile una conversione per l'esterno.
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.
