Steel flange floating ball valve
Category： Ball valve series
Summary： The ball valve is a valve that uses a ball with a circular through hole as the opening and closing part, and the ball rotates with the valve stem to realize the opening and closing action. Perfectly equal valve body chambers provide a low-resistance, straight-through flow path for the medium. The ball valve not only has simple structure and good sealing performance, but also has small size, light weight, less material consumption, small installation size, and small driving torque within a certain nominal diameter, easy operation, easy to achieve fast opening and closing, easy to operate and maintain.

The main characteristics and uses of ball valves
The ball valveis a valve that uses a ball with a circular through hole as the opening and closing part, and the ball rotates with the valve stem to realize the opening and closing action. Perfectly equal valve body chambers provide a low-resistance, straight-through flow path for the medium. The ball valve not only has simple structure and good sealing performance, but also has small size, light weight, less material consumption, small installation size, and small driving torque within a certain nominal diameter, easy operation, easy to achieve fast opening and closing, easy to operate and maintain. Ball valve is divided into floating ball valve and fixed ball valve, floating ball valve mainly relies on the medium pressure to press the ball on the outlet end seat to achieve sealing, its use pressure and diameter are limited. The ball body of the fixed ball valve is supported by two bearings installed on the valve body, the ball position is fixed, and the valve seat is pressed against the ball by spring and medium pressure to achieve sealing. The ball valve body is available as integral type, two-piece type and three-piece combination type.
The working principle of the ball valve is that the opening and closing parts are used as a sphere, and the ball is rotated 90° around the axis of the valve stem to achieve the purpose of opening and closing.
Ball valvesare mainly used to cut, distribute and change the flow direction of media on various pipeline systems, and ball valves designed with V-shaped openings also have good flow regulation functions. Ball valve is very widely used, the variety and number of use is still continuing to expand, and to high temperature, high pressure, large diameter, high sealing, long life, excellent adjustment performance and a valve multi-function direction, its reliability and other performance indicators have reached a high level, and has partially replaced gate valves, globe valves, throttle valves. It has been widely used in aerospace, petrochemical, long-distance pipelines, light industry food, construction and many other aspects. It is suitable not only for working media such as water, solvents, acids, alkalis and natural gas, but also for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene.
