Disc Valves

Air valves offer a simple yet effective means of providing supply and extract air for most commercial, industrial and domestic ventilation applications. The disc valves consist of a valve ring, central disc and installation sub frame.
COSMOS disc valves are best suited to air distribution system handling relatively low air flow rates within small circular ductwork.
Disc valves are Ideal for handling exhaust of greasy and damp areas like kitchen, restroom etc. They can be use for ventilation as well as supply applications.
The air volume flow rate is adjusted by rotating the central disc which alters the size of the gap. This results in changes to acoustic and pressure drop figure. The central disc is held in position with a locknut.
