Description
Features
- It ensures the evacuation of air when filling the wastewater main transmission lines and ensures sufficient air entry into the pipe during line discharge.
- It is a self-operating automatic control element that prevents shocks resulting from sudden closing.
- The body cross-sectional area has the minimum cross-sectional area of the valve nominal diameter with the large stainless floater cross-sectional area at the air outlet.
- In this way, the amount of fluid entering the body is not subject to narrowing at the outlet, thus increasing the air discharge capacity.
- It has an aerodynamic structure that prevents premature closing without disrupting the air flow.
- Metal parts in contact with the fluid are protected against corrosion by using AISI 316 stainless steel.
- Flanged connection according to EN 1092-2.
- Sealing and orifice NBR gaskets.
- Working pressure range: 0.2 – 16 bar.
