butterfly valve series-九游官网下载

product overview 

the pneumatic high-performance butterfly valve has a unique product structure and a floating seat design. according to the direction of the pressure source, the seat position is automatically adjusted to achieve the double-sided pressure-sustaining sealing effect of the valve and increase the service life of the valve seat. the valve shaft is specially designed for dust prevention to prevent fluid from entering the valve shaft and causing the valve shaft to be stuck. different materials and properties can be selected according to different working conditions. the valve seat is made of ptfe, rtfe, peek, metal and other materials. pneumatic high-performance butterfly valve is suitable for petrochemical, oil refining, air separation, cda and other working conditions.

the valve is widely used in the transportation of liquids and gases (including steam) in various industrial pipelines. it can also be used for special media such as oxygen, high vacuum, sulfur-resistant or corrosive media. the product can also have a fireproof structure as an option. the connection method can be a wafer type or a lug type single flange design for large pipe diameters and pipeline terminals.
