ASTM Material Standerd Fully Welded Ball Valve NPS 2"-48" PN 20-420 Class 150-1500

Application
Floating ball valves are suitable for use on various kinds of pipelines of class 150-class 1500,pn 16-pn100,JIS 10K-JIS20k to turn on or off the pipeline medium,of which the operation types include manual,worm gear and pneumatic or electricactuators.

Reliable seat seal
The structure design of elastic sealing ring has been adopted for floating ball valves.This seat design features a bigger sealing pressure ratio between the ring surface and the ball when medium pressure gets lower,where the contacting area is samller.Thus,the reliable seal is ensured.When the medium pressure gets highter,the contacting area between seat ring and ball becomes bigger as the sealing ring transforms elastically to undertake the bigger force pushed by the medium withour any damage.
