Air Valve Triple Functions TYPE PP with quick anti-fill device - Threaded connection
The automatic triple-function air valve with 1" and 2" gas thread in glass fiber reinforced polypropylene has been designed to allow the release of air pockets accumulated in working conditions, the entrance of large volumes of air in case of pipe draining or bursts and to prevent pipeline damages coming from pressure transients, associated with high air outflow velocities.

| 1" (24/36) | PP | 80 | 167 | 92 | CH 41 | 0.3 | 293289 |
| 2" (50/60) | PP | 110 | 226 | 135 | CH 65 | 0.7 | 293290 |
Features
It can be fitted with the following options:
- EO: Air outlet only device when the air valve is located at points where the piezometric line may drop below the pipe profile, or for installations where air introduction must be avoided (suction pumps, syphon pipes).
- IO: High-flow air inlet and air exhaust flow regulation device.
Application
- Irrigation systems
- Water distribution networks
- Cooling systems, process and industrial installations
Main characteristics
- Single chamber body in glass fiber reinforced polypropylene PN16, provided with internal ribs for accurate guiding of the float.
- The aerodynamic full-bore body prevents premature closure of the moving assembly at high air intake and outlet velocities.
- Fitted with dynamic seals to prevent leaks at low pressures.
- Maintenance can be easily performed from the top without removing the air valve from the pipe.
- Compact and reliable structure whose parts are fully corrosion and chemical resistant. Lower maintenance
- Male BSPT or NPT threaded connection.
