Stainless Stell CF8 CF8M 1000WOG 3PC Type Threaded Welded Ball Valve
Product introductioin:
Floating ball valves can be divided into 1-piece, 2-piece, and 3-piece types in terms of structure. Three piece ball valves and gate valves belong to the same type of valve, with the difference being that their closing member is a ball, which rotates around the centerline of the valve body to achieve opening and closing.
The valve body of a three piece ball valve is composed of a main valve body and two auxiliary valve bodies, so it is called a three piece ball valve. After the ball core and valve stem are installed in the main valve body, the auxiliary valve body is installed in the valve seat, and the main and auxiliary valve bodies are connected together by bolts. Its core flow channel is also of full bore size. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of the medium. Three piece ball valve is a widely used new type of valve.

Product features:
1. High reliability: The three piece ball valve has a compact structure, good sealing, flexible operation, and convenient maintenance, so its reliability is extremely high.
2. Low flow resistance: The sealing surface between the ball and the valve seat is large, and the flow channel is unobstructed, resulting in low flow resistance and excellent flow characteristics.
3. Long service life: The friction between the ball and the valve seat is small, resulting in a longer service life.
4. Full open and full close: The three piece ball valve can achieve full open and full close operation, making it easy to control the flow rate of the medium.
5. Wide applicability: The three piece ball valve is suitable for special working conditions such as high temperature, high pressure, and corrosion resistance, and has good applicability.
