GS8
The model G.S.8 pinch valves (normally closed) have an automatic, double, spring closing device and correspondingly double apparatus for hand and hydropneumatic remote opening; this latter is done by simultaneous and balanced action of the pressure in the two cylinders.
By means of the device closing and opening is made easier and regulation of flow more accurate. Diameters of the G.S.8 go from 80 to 200.
