Damper Butterfly Valve
Description
The butterfly or wafer damper can be a stack damper where sealing or tight shut-off is not all-important. This type is used as an isolating damper for flue-gas scrubbers. The butterfly damper is lightweight, simple, quickly actuated, and often comparatively low in cost. In process work, oval shapes adapt to the shape of the duct. Occasionally, a double-disc butterfly appears, resembling a circular two-bladed louver damper. The drive for a butterfly damper is also simple, needing only 90° of motion. The torque requirement can vary widely over damper life if corrosion and thermal effects are severe. Hand levers, Gear boxes, Pneumatic Actuators, or Electric, motorized damper valve actuators are used to actuate butterfly dampers. Size Range: 8″- 120* Above on Request.
