Keywords: Stainless Steel, mild steel, Material Of Construction

Bulkmatic Butterfly Dampers are available as motorised, pneumatic or hand operated units. They can be supplied with accurate positioning actuators or as a simple open / closed configuration. The shaft stubs are bolted to the robust damper blade. This allows the blade to be replaced.

Sealing strips are fitted to the damper casing and the damper blade closes against the strip. The damper blade and casing flanges are lasercut allowing for precision fitting holes and accurate alignment of the shaft stubs. The shaft stubs are fitted with stuffing glands to seal against a pressure differential where necessary.

The shaft stubs are bearing mounted and the nondriven shaft can be fitted with limit switches. Standard sizes are available to match standard nominal bore ducting or pipework but non-standard diameters can be manufactured to suit. This is particularly relevant where an existing damper needs to be replaced.

Material of construction is mild steel. Stainless steel and high temperature versions are available on request.

Standard sizes include: 200, 250, 300, 400, 500, 600, 700 and 800.
Other sizes and configurations are supplied on request.
