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.
