Single Vane (Butterfly) Dampers

Single vane dampers are best suited for open/closed duty as the sealing periphery is minimal relative to duct area. However, where cost is of prime consideration, single vane units offer reasonable modulating control but create more disruption to flow than multivane dampers.

A typical application for manual dampers is regulating or ‘trimming’ where the vane remains in a fixed position for long periods in order to maintain a constant flow control through the system.

 

 

We can design and manufacture a wide range of sing vane and butterfly dampers for a wide variety of applications in any size required.
