Air disc valves

Air disk valves are the most frequently used for air exhaustion from sanitary facilities, but can also be used for air supply. There are also available universal disk valves intended both for supply and exhaust air in our assortment. The valve is composed of an inlet cone and of an adjustable central disc enabling the air flow regulation.

The air flow through the disk valve can be adjusted by rotating the disc clockwise or anticlockwise. Dish valves operate with relatively low air flows from 30 to 200 m3/h, are manufactured in diameters of 80 to 200 mm. HVAC disc valves are made of either plastic or sheet steel, which is standardly varnished.

Description

Disc valves are used as an alternative to ceiling diffuser. They are most commonly used for the purpose of ventilation. The air flow through the disk valve can be adjusted by rotating the disc clockwise or anticlockwise. The rotation changes the free area between the disc and the frame.
Disc valves are preferred by many architects and building owners for toilets, bathrooms and ventilation in damp areas due to its simplistic yet aesthetic appearance. The sizes starts from 80mm up to 200mm Diameter. The fixing is very simple. Please refer to the catalogue for more details on fixing and air flow details.
Description:

• Frame and disc is made of high quality galvanized steel sheet construction with powder coated to RAL colors.
• Disc is attached to the frame by threaded rod.
• Air flow can be adjusted by regulating the cone up or down (+A or -A)
• Foam gasket is sealed around the back of the frame as option to avoid air leakage.
• These valves can be used for supply, exhaust and ventilation applications.
• Air master disc valves are best suited to air distribution systems handling relatively low air flow rates within small circular duct work.
• Can be mounted in wall, ceiling or exposed air ducts with mounting rings.
• Recommended for exhaust of greasy and damp air in damp areas such as toilets, bathrooms and kitchens.
