Air Valves

-Flange and hole dimensions according to: UNE-EN 1092-2 PN10 / PN16.

CHARACTERISTICS:

The air valve contains a kinetic valve and another valve for automatic air evacuation in a single body. In the sanitary system its function is to release and admit the air (gases) from the sewage water’s. The exclusive structure of this air valve guarantees the complete liquid split from the closure system and provide optimal working conditions. For a correct operation, the minimum working pressure must be at least 1,5 bar.

OPERATION:

During pipeline filling, the air pockets (gases) are reléase at high flow rates through the kinetic valve orifice.
It admits a large volume of air during the emptying of the pipelines. Under normal operating conditions, water streams with debris are in the line, and the kinetic valve orifice remains closed, because the release valve stops passing the air that accumulates through the automatic valve. The mechanism prevents the automatic nozzle opening at every small change of pressure in the line, and ensures a gap between the seal system and the contaminated liquid.

– Flange dimensions and holes according to UNE-EN 1092-2 PN16.
– Holes dimensions according to UNE-EN 1092-2 PN10 / PN16.

DESCRIPTION:

This air valve allows:
– The outlet of high flow of air during filling the pipeline.
– The degassing under pressure (up to 16 bar).
– The inlet of high flow of air during emptying of the pipeline.
