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 apipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs.
"Combines the features of both an air & vacuum valve and an air release valve.
Air & vacuum component discharges large volumes of air during filling of the system.
Air & vacuum component admits large volumes of air during drainage and at water column separation.
The air release component releases entrapped air in pressurized systems.
Dynamic design allows for high velocity air discharge while preventing premature closure.
Innovative rolling seal mechanism."
