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 valve will open to relieve negative pressures whenever water column separation occurs.

Working pressure range:
D-060, D-060-C – 0.2-16 bar.
D-062 – 0.2-25 bar.
D-065 – 0.2-40 bar.
Combines the features of both an air & vacuum valve and an air release valve.
Triple function:
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.
All main flow cross-sections are equal or greater than the nominal port area.
Aerodynamic design enables high flow rates of air both at intake and at discharge.
Special orifice seat design: combination of bronze and E.P.D.M. rubber assures long-term maintenance-free operation.
Available in flange sizes: 2″ – 10″ (2″ – 8″ D-065 only).
These valves are manufactured with flanged ends to meet any requested standard.
