The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure.
The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This air valve will open to relieve negative pressures whenever water column separation occurs.
The valve’s unique design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.

The valve’s rolling seal mechanism design enables a one size orifice for a wide pressure range:
Polypropylene: 0.02 – 10 bar
Reinforced Nylon / PVDF: 0.05 – 16 bar
St.St. SAE 316 / Duplex : 0.05 – 25 bar
Dynamic design allows for high velocity air discharge while preventing premature closure.
Builds an air gap that separates the liquids with suspended particles from the sealing mechanism.
Available in male threaded sizes: 1/2”, 3/4”, 1”, 2” – BSP / NPT and 2” flanged
