SAMPI VP-Series Pneumatic Valves User Manual
Vp-series pneumatic valves specifications sheet, Operating states, Materials
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.
