Air valve

Design and application

- Aluminum blades with soft plastic seal along the edge of the blades.
- Aluminum frame.
- The rotation of the vanes is done by means of polymer gears mounted inside the air valve frame.
- The stem, through which the rotation force is transmitted, has a square cross-section and is designed to mount the servo drive (air valves larger than 4 m2 have two stems connected by a pull rod).


Features  

- Leakage when the valve is closed: 50 m3/h*m2 - at a pressure difference of 100 Pa.
- Environment: -40 ÷ +70°C
