Control valves

Smitsair B.V. Volume control valves are specifically designed for controlling air volumes, mixing airflows and/or sealing off airflows. Our valve housings are suitable for mounting on or in ventilation ducts, against an outer wall recess, or combined with and mounted behind our ventilation grilles.


Our valve housings are tested for airtightness in line with NEN-EN 1751. According to this test, all our valve housings are classified as airtightness Class C. A large number of them are even classified as airtightness Class D.
