D-43 | Combination Air Valve "BARAK PRO"
10 BAR –2"
Description
The D-43 series Combination Air Valve has the features of both an air release valve and an air & vacuum valve. 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.
Product Features
- Combines the features of both an air & vacuum valve and an air release valve.
