Combination air valve for water and neutral liquids to max. 60°C (temporarily up to 90°C)
AVK combination air valves are combined air release and air and vacuum valves. The air release function releases accumulated air from the system while it is under pressure. The air and vacuum function discharges and admits large volumes of air during the filling or draining of pipelines. The valve will open to relieve negative pressures whenever water column separation occurs. The body and all operating parts are made of specially selected corrosion-resistant materials.
| Variant 701/48-011 | |
|---|---|
| Connection: | Flanged |
| Material: | Ductile Iron |
| DN: | DN50 - DN200 |
| PN: | PN 16 |
Features
-
Available in 80, 100, 150, 200mm flange
- Optional with non-slam element which reduces water hammer incidents
- Dynamic design allows for high capacity air discharge while preventing premature closure
- The discharge outlet enables the connection of a vent hose/pipe
- Large size of the automatic air release orifice relative to the air valve body:
- Discharges air at high flow rates
- Enables the usage of the rolling seal, making it less sensitive to pressure differential than a direct float seal
- Body is made of ductile iron
- Due to its light weight, the valve may be installed on plastic piping systems, as well as other lightweight piping systems
- Minimum down-time for maintenance – all operating parts are consolidated into one replaceable cartridge
- When impure water accumulates above the sealing, it can be be drained in order to avoid entering the system during vacuum conditions
