The Beaver A01–A06 Combination Air Valve has a multi-function design that makes it light, reliable, and easy to install.
The air valve’s three functions are to expel air that accumulates during filling, let in air during emptying to prevent vacuum formation, and remove air pockets when the valve is pressurised.
This series of Beaver Combination Air Valves is suitable for drinking water, sewage, irrigation, and water supply.
