D-040 L | Combination Air Valve for Small Suspended Solids for Low-Pressure Systems

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.
