Butterfly Damper


Butterfly Damper

Venti-Tron butterfly dampers offer an easy-to-use and reasonably priced control and isolation solution. We may use a variety of sealing configurations, such as seal air fans, to offer the precise sealing efficiency needed for your application.
Although carbon steel or stainless steel are the two materials that may be used to make Venti-Tron Butterfly Dampers, we can use any material for unique applications.


Our Butterfly dampers can be operated manually with a straightforward hand lever or reduction gearbox, electronically, or pneumatically. To meet your needs, we can provide both normal range damper valves and custom butterfly dampers.

Although Venti-Tron may offer PED compliant dampers for greater pressure applications, high specification dampers for harsh temperatures, and particularly designed dampers for use in corrosive process settings, butterfly dampers are mostly employed in low pressure flow control situations.
