The Beaver A07–A09 3-Function High-Pressure Air Valve performs a combination of functions and is specifically designed for high pressure services.
The valve works in three ways. First, it exhausts air that accumulates during the filling process. It also allows air in during emptying to prevent vacuum in the pipe. Finally, it expels air pockets that form when the valve is pressurised.
Beaver High Pressure Combination Air Valves are suitable for drinking water, sewage, irrigation, and water supply.
