HVAC Supply Steel Round Air Disc Valves Diffuser For Ceiling

Disc valves are used as an alternative to ceiling diffuser. Frame and disc is made of high quality galvanized steel sheet. The valves can be used for supply, exhaust and ventilation applications. The air flow through the disk valve can be adjusted by rotating the disc clockwise or anticlockwise, air flow rate may be adjusted also by adjusting the cone up or down. The rotation changes the free area between the disc and the frame.
