/ 12 | Valves Design TFF is made from galvanized steel sheet with powder colour coating. The product consists of the fixed part with fixing springs, equipped duct connection, the valve seat and the movable valve front plate. The front plate is held by the central thread bolt and can be moved by rotating. So the gap between the plate and the seat can be adjusted to set the required air flow volume.
