The pneumatic valves can be used to intercept

hydrocarbons such as diesel, gasoline, kerosene,

airplane fuel products and various solvents with the

exception of special versions requested by clients for

the specific use.

In standby (no low flow and high flow air supply) the

shutter, attached to the shaft, presses on gasket

thanks to the action of a spring preventing the “IN”-

“OUT” passage. Once closed, the action of the spring is

reinforced by the force due to the differential section

defined by the construction diameters of the shutter

and its inner guide (not shown in the figure) which

contributes to the “seal” of the valve.
