The NGV A3 Valve with:
·
the new Fluitronic digital technology.
·
the “Stepping System” device
·
the possibility to use ecological fluid or traditional mineral oil
·
the working pressure between 12 and 45 bar
Guarantees :
- Increased reliability of the control system
- Best performance
- Reduction of costs
- Reduction of the installed power (up to 20%)
- Reduction of consumptions up to 40% (*)
- Reduction of the travel time

The choice to immediate savings, interfaced with all, existing and
new systems
Not require encoder, reduce consumption up to 20% *
The valve, stored the operating characteristics, reading changing of
pressure and temperature, make the appropriate corrections to
obtain car speed profiles with low deviations from the ideal profile.
* Compared to a traditional valve
1.2 THE FLUID
GMV use and recommend an hydraulic fluid ISO VG 46 that :
·
Thanks to classification as category HEES, as rule ISO-UNI 6743-4 and
its biodegradability index > 90%, according to standard CEC L33-A-
93, is acceptable from an environmental point of view.
·
Thanks to the synthetic base (ISO VG 46 ) and its viscosity index
(>140), higher than the traditional mineral oil, allowing greater stability,
ensuring better performance against wear and aging on systems as
lifts for persons and goods, in accordance with the environmental
directive 2006/118/EC.
·
Thanks to a flash point above 220°C compared to the 140°C of the
traditional mineral oil it is safer and reduces the risk of fire.
