What is Double Orifice Air Valve?

The Dual Orifice Air Valve is an innovative combination of a small and large orifice air valve in a compact cylindrical housing. The function of the large holes is to allow a large amount of air to enter during the duct discharge phase and to expel a large amount of air during system filling.

Under operating conditions, any small air accumulations are expelled through the small holes. The novel design has corrosion-inhibiting components acting through the center shaft and reduced weight compared to the comparative unit.

Application of Double Orifice Air Valve

Used to prevent pressure build-up in piping systems, vacuum and control gas emissions for stability. Suitable for potable and filtered water applications. Please see our Dual Bore Data Sheet below under our Using Air Valve Documentation and Technical Characteristics tab.
