Single Small Orifice
Single Large Orifice
High Speed Air Valves with Resilient Orifices
Air valves have been especially designed to allow the most efficient method of releasing or admitting air during the filling and emptying pipelines or vessels and the release of air accumulating in pipeline during normal working conditions.
Small Orifice - Automatically releases accumulates air in pipeline
Large Orifice - Automatically releases or admits large volume of air for efficient filling or emptying or pipelines to protect against vacuum or pipeline damage
Double Orifice and High Speed (quick type) - The combination of small and large orifice becomes a single unit.
Double Orifice with integral Isolating Valve - The combination of small and large orifice plus integral isolating valve becomes a single unit
