Recently, our company has completed a batch of DN800 big size offset butterfly valves, the specific specifications are as follows;

Body: WCB
Disc: WCB
Seal: SS304+Graphite
Stem: SS420
Removable seat: 2CR13

NSEN can provide customers with valve diameters DN80 – DN3600. Compared with gate valves and ball valves of the same size, large-diameter butterfly valves have simple structure and could greatly shortened structural length, reduced weight. And only need to rotate 90 ° to quickly open and close, simple operation.

The three-eccentric butterfly valve has the following characteristics;
①The unique design of three eccentricity makes frictionless transmission between the sealing surfaces and prolongs the service life of the valve.

②The elastic seal is produced by torque.

③The clever wedge design makes the valve have the function of automatic sealing, make the sealing tighter, and the sealing surfaces have compensation and could reach zero leakage performance.

④Small size, light weight, light operation, easy to install.

⑤ Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.

⑥The material of the parts can be replaced to adapt to various media

⑦Different connection type: wafer, flange, butt welding.
