Three-piece Stainless Steel Ball Valve,Three-piece Ball Valve,Ball Valve

Three-piece butt welded ball valve refers to the closing part is a ball, the ball is rotated around the center line of the valve body to achieve the opening and closing of a valve. Ball valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Three-piece ball valve is a new type of valve widely used in recent years.

Three-piece butt welded ball valve and flange gate valve are the same type of valve, the difference is that its closing part is a ball, the ball rotates around the center line of the valve body to achieve the opening and closing of a valve. The electric ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Two-piece ball valve, three-piece ball valve, is a new type of valve widely used in recent years, this type of valve in the pipeline generally should be installed horizontally.

Two, three piece butt welding ball valve advantages

one The fluid resistance is small, and its resistance coefficient is equal to that of the pipe segment of the same length.

2. Simple structure, small size, light weight.

3. At present, the sealing surface material of stainless steel electric ball valve is widely used in plastic, good sealing, and has also been widely used in vacuum systems.

4. Easy to operate, open and close quickly, from full open to full close as long as the rotation of 90 degrees, easy to remote control.

5. Easy maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.

6. When fully open or fully closed, the sealing surface of the ball and the seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when it passes through.

7. Wide range of application, small diameter to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.

Three, three piece butt welding ball valve implementation standard

1. Design and manufacture: GB12237-89, API608, API 6D, JPI 7S-48, BS5351, DIN3357.

2, flange size: JB/ T74-90 (JB74-90), GB9112-9131, HGJ44-76, SH3406, ANSI B16.5, JIS B2212-2214, NF E29-211, DIN2543.

3, structure length: GB12221-89, ANSI B16.10, JIS B2002, NF E29-305, DIN3202.

4. Main test: JB/T 9092, API 598.

Because of its easy maintenance characteristics, the three-piece ball valve is suitable for occasions with higher requirements for tightness and durability, such as high pressure, high temperature, corrosive media pipeline systems in oil, natural gas, chemical and other industries. In addition, the three-piece ball valve also has significant advantages in conditions requiring frequent disassembly and cleaning, such as food, pharmaceutical and other industries.
