Napomene
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
Aktiviranje ovih ventila odvija se putem magnetskog višesmjernog ventila NP6 u izvedbi s reduciranim propuštanjem ulja koji se dograđuje kao pilot ventil (tip HK DHE...P...).
Aktiviranje se odvija interno, moguća je preinaka na eksterno.
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.
