Three-way cast iron suction cup without a flanged shut-off valve

When installed in networks, the air vent prevents air accumulation at the highest points of the pipes and protects against vacuum formation.
For crossings over roads and rivers, and at changes in slope, it provides protection against overpressure and water hammer (upon request) at points where the water column breaks
. At pumping stations, it protects pumps, facilitates purging, and provides protection against overpressure and vacuum (upon request)
Straight-through body with inlet and outlet of identical diameters
Aerodynamic kinetic protection (prevents premature closure without disrupting air inlet or outlet).

Features:

• High-flow air outlet
