Vītņu Pretvārsts Giacomini N5 Clapper Ar Gumijas Blīvi

The clapet check valves with N5 rubber-metal seal are single-direction
devices which prevent the return of pressurised fluid.
They are suitable for use in domestic water systems, raised water systems, fire
protection, central heating and boiler room systems, solar plants, and water
systems for industrial and agricultural applications in general.
The internal hydraulic seal is ensured by the forces exercised by the mass of a
tilting shutter and by the pressure of the liquid above a gasket which activates
the seal, even when subject to minimal back pressure.
Due to the fact that these valves function via the gravitational force that acts
on the tilting shutter (clapet or swing), there is no universal guideline as to
where these should be positioned. The advantage of these valves is the low
incidence of losses of pressure due to the rounded shape of the valve body
and the large passage section which is obtained via the oscillation of the
shutter; these elements also mean that they are extremely quiet.
