Automatic air valve for water and neutral liquids to max. 60°C (temporarily up to 90°C)
AVK automatic air valves are designed with a very soft and sensitive seal. It enables effective discharge of accumulated air from the system while it is under pressure. The automatic air release valve are lightweight and compact with a 12mm2 orifice enabling a release of air at high flow rates not being exposed to obstruction by debris. All operating parts are made of specially selected corrosion-resistant materials.
| Variant 701/10-001 | |
|---|---|
| Connection: | External BSP Thread |
| Material: | Reinforced polyamide |
| DN: | DN12 - DN25 |
| PN: | PN16 |
Features
- Orifice size of 12 mm²
- The enlarged orifice is less exposed to obstruction by debris
- The orifice in the automatic valve releases large volumes of air at high flow rates when the line is under pressure
- The valve’s rolling seal mechanism design is less sensitive to different pressures than a direct float seal, thus enabling a one size orifice for a wide pressure range (from 0.2 up to 16 bar)
- Body of high-strength composite material
- All operating parts of corrosion-resistant materials
- Very low weight
- With BSP thread connection
- Working pressure range: 0.2 – 16 bar
