Feature :

1) No abrasion for on-off, which fully resolves the problem of mutual abrasion affecting sealing performances of sealing surfaces traditional valves.

 

2) Uploading construction, with which  the valves on pipelines could be online checked and repaired directly. Thus the engine-stopping could be effectively minimized to reduce the production cost.

 

3) Single seat design, which  eliminates those problems affect safety caused by abnormal temperature-rise from the medium in the umen of the valve.

 

4) Low to sional moment design, with the stem with specially designed structure could be opened or shut down with down with merely a small hand wheel valve.

 

5) Wedge type sealing construction. Traditionally the valve would be sealed through the mechanical force provided by the stem to widge press the ball onto the valve seat. with this design, the sealing performance of the valve would never be influence by the fluctuation of the prissure differences in pipeline and the performance would be reliably maintained under all the operating modes.

 

6) Self purging constrution of sealing surfaces. The fluid inside the pipeline would pass through evenly by 360 & ordm, along the sealing face on the globe body when the body sidingly leaves the seat. This design not only eliminates the scouring on parts on valve seat by high speed fluid, but also washes away the piled up matters on the surface to realize self purging.
