説明
Stainless Steel Ball Valve is one type of quarter-turn valve, is quite literally a ball placed in a passageway through which fluid flows. The ball has as a hole through it, by which the valve opens and closes. The ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium.
Two-Piece Ball Valve (2pc)
This design ball valve consists of two separate pieces, one is the valve bodies, the other is a bonnet (cap).
For 2pc screwed ball valve, the connection between them being either threaded.
For 2pc flanged ball valves, with the 4 or 6 bolts connection between bodies and flange ends.
The below photo is our 2pc ball valve Korea type, we both have a standard port(Reduced bore) & full bore design.
アドバンテージ:
1. Between the same quality ball valves, the 2-piece ball valve is relatively more resistant to high pressure.
2. When the valves leaks, it could be repaired by changing the sealing or packing.
Disadvantage:
When replacing parts, the valve needs to be removed from the pipeline and connection only in thread or flanges.
