Description & Features

Ventilation Butterfly Valve is a regulating valve with a simple structure and can also be used for on-off control of low-pressure pipeline media. It using the same material into the valve body seals, the applicable temperature varies depending on the selection valve. Its structure is simple, compact, and the product itself is light in weight. This Ventilation Butterfly Valve is generally applicable to industry, metallurgy, environmental protection, regulating media flow conduit for ventilation purposes.

● Ventilation Butterfly Valve has novel and reasonable design, unique structure, light weight, and rapid opening and closing.

● It has small operating torque, convenient operation, simple installation method, low internal resistance, and can well solve the problem of high temperature expansion.

● This valve uses materials that adapt to different medium temperatures and corrosive media, with strong working reliability and long service life.

● Flattened body bore at shaft journal ports positions shaft bearings near disc, providing maximum shaft support resulting in reduced wear and longer life.
