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: 15mm, 20mm, 25mm, and 50mm threaded male connections, 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.
