The difference
The fundamental difference between one-piece ball valve, two-piece ball valve and three-piece ball valve lies in the structure of the valve body.
The one-piece ball valve has a reduced diameter, the ball is fixed by a plug, and the flow rate is relatively small;
The two-piece ball valve is a full-bore valve. It is fixed by two pieces of the valve body clamped by the ball. The maintenance is relatively complicated. The tightness of the screw in the middle is very important, which is related to whether there is air leakage. Better sealing;
The three-piece ball valve is similar to the two-piece ball valve, and it is also full-bore, but there is a valve body in the middle of the ball, which is clamped by the neck flanges on both sides, which can withstand better pressure, is easy to install, and is easy to disassemble, maintain and clean.
