DG-10 | Combination Air Valve "Barak"
PN 10 – DN15, DN20, 25 ,50
Description
The DG-10 combination air valve has the features of both an air release valve and an air & vacuum valve. The air release component of the combination air valve was 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 was 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.
- 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.
- Dynamic design allows for high velocity air discharge while preventing premature closure.
- Innovative rolling seal mechanism.
- Available in sizes: 3/4", 1", 2" threaded male connections, NPT or BSPT.
Application Range
- Working pressure range: 0.1-10 bar.
- Maximum operating temperature: 60°C.
- Maximum intermittent temperature: 90° C.
- For installation:
- At pump stations.
- Downstream and upstream of shut-off valves.
- After deep-well pumps.
- On long constant-sloped pipeline segments.
- At peaks along the pipeline and at peaks relative to hydraulic gradient.
- Additional protective shell for anti-vandalism/theft applications.
