Butterfly Dampers

DTL Butterfly dampers provide a simple and cost effective method of control and isolation. Stainless steel dampers for high temperature applications are available in a variety of sizes. Various sealing arrangements can be used to provide the correct efficiency for your application.


Sealing efficiency can be increased to 100% with the addition of twin seals and a sealing air fan. Butterfly dampers can be actuated pneumatically, electrically or manually by a simple hand lever or reduction gearbox.
