Butterfly Dampers are available as motorized, pneumatic or hand operated units. They can be supplied with accurate positioning actuators or as a simple open I closed configuration. The shaft stubs are bolted to the robust damper blade.This allows the flap to be replaced easily. Sealing strips are fitted to the damper casing and the damper blade closes against the strip.The damper blade and casing flanges are laser cut allowingfor precision fitting holes and accurate alignment ofthe shaft stubs.The shaft stubs are fitted with stuffing glands to sealagainst a pressure differential where necessary. The shaft stubs are bearing mounted and the non driven shaft can be fitted with limit switches. Standard sizes are available to match standard nominal bore ducting or pipe work but non-standard diameters can be manufactured to suit.This is particularly relevant where an existing damper needs to be replaced.
