What is ?
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 and Technical Characteristics tab.
