2-Piece Ball Valves
2-Piece Ball Valves: Introduction, Advantages & Technical Parameters
A 2-piece ball valve is fixed by clamping the ball between two valve bodies. It is a commonly used ball valve. Its main feature is that the valve body is composed of two hemispherical parts. Due to its simple structure and mature manufacturing process, it is widely used, especially in occasions that require frequent control of fluid flow direction and flow rate.
Main Advantages of 2-Piece Ball Valves
Lightweight: The imported 2-piece ball valve has a simple structure, and the hemispherical valve body design makes it lighter and easier to install and maintain.
Flexible Operation: The flow direction and flow rate of the fluid can be easily controlled by rotating the ball, making the operation very simple and convenient.
Excellent Sealing Performance: The sealing structure of the imported 2-piece ball valve adopts the seal between the ball and the valve seat to control the fluid flow direction, with good sealing performance and effective leakage prevention.
Long Service Life: The imported 2-piece ball valve has a simple structure, mature manufacturing process, good corrosion resistance and long service life.
2-Piece ball valves are widely used in pipeline control systems in petroleum, chemical, pharmaceutical, metallurgy and other industries, as well as in municipal engineering and construction fields.
