What is The Different 3 Piece Ball Valve and 2 Piece Ball Valve
The 2 piece ball valve is called the stainless steel ball valve, which is composed of the left and right valve bodies bolted together. When fixing, the two valve bodies clamp the ball valve, which is relatively difficult to maintain. The key is to see how tight the screw in the middle is, which is directly related to whether the seal is tight. In addition, it is mainly used in atmospheric and high-pressure environments, and non-standard valves with nominal diameters below DN50 also belong to the 2 piece type. A 2 piece ball valve is a commonly used valve that is fixed by clamping the ball with two valve bodies, and maintenance is complex. The tightness of the middle screw is crucial, which determines whether there is air leakage. The three piece ball valve is similar to the two piece ball valve, but the three piece ball valve can be used in ultra-high pressure environments, and the valve structure design will have a three piece valve body, which is clamped and fixed by the left a...
