Introduction of one or three-piece butt-welded ball valve

(3PC • BW) Q61F-16 / 64 (C, P, R)

是指关闭件是个球体,球体绕阀体中心线作旋转来达到开启、关闭的一种阀门。 A three-piece butt-welded ball valve is a valve in which the closing member is a sphere, and the sphere rotates around the center line of the valve body to open and close. Ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. Three-piece ball valve is a new type of valve widely used in recent years.
The three-piece butt-welded ball valve and the flange gate valve are the same type of valve. The difference is that the closing part is a sphere.   在管路中主要用来做切断、分配和改变介质的流动方向。 The electric ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. Two-piece ball valve and three-piece ball valve are a new type of valve that has been widely used in recent years. This type of valve should generally be installed horizontally in the pipeline.

Advantages of two or three-piece butt-welded ball valves

1. The fluid resistance is small, and its resistance coefficient is equal to the pipe length of the same length.
2. Simple structure, small size and light weight.
3. 不锈钢电动球阀 的密封面材料广泛使用塑料、密封性好,在真空系统中也已广泛使用。 It is tight and reliable. At present , the sealing surface material of stainless steel electric ball valves is widely used in plastics and has good sealing performance. It has also been widely used in vacuum systems.
4. Easy operation, fast opening and closing, only need to rotate 90 from fully open to fully closed, which is convenient for long-distance control.
5. Easy maintenance, simple ball valve, seals are generally activities, removal replacement is more convenient.
6. When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes.
7. Wide range of applications, from small diameter to several millimeters, large to several meters, can be applied from high vacuum to high pressure.
