Product Introduction:

On-off electric wafer butterfly valve model D971X adopts concentric resilient seated design. 

The multi-drilled valve body is compatible with GB PN10/PN16, ANSI Class150, JIS 10K and EN PN16 flanges. 

One valve fits different international pipeline standards, which makes it the preferred choice for overseas projects and export equipment.


Equipped with on-off electric actuator, the valve realizes fully open / fully close two-position control by 90° rotation of disc, used for pipeline shut-off. 

Wafer mounting structure is compact and lightweight. Resilient seat provides bubble-tight bi-directional sealing.

 

Advantage: 

Universal multi-standard body reduces inventory varieties. Electric two-position automatic control supports remote operation, ideal for unattended pipeline systems.
