A ball valve is a valve that uses a ball with a circular channel as the opening and closing element, and the ball rotates 90 degrees with the valve stem to achieve the opening and closing action. The opening and closing component of a ball valve is a perforated sphere that rotates around an axis perpendicular to the channel to achieve the purpose of opening, closing, or adjusting the channel. Ball valves can be used for regulating and opening/closing on pipeline equipment. The main characteristics of ball valves themselves include compact structure, reliable sealing, simple structure, relatively small volume, light weight, easy maintenance, no vibration, and low noise. The sealing surface and spherical surface are often in a closed state, which is not easily eroded by the medium, easy to operate and maintain, suitable for general working media such as water, solvents, acids, and natural gas, and also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane, and ethylene. They are widely used in various industries. The ball valve body can be integral (one-piece) or modular (two-piece and three piece).<a href="https://www.1ballvalves.com">Ball Valves</a>
Ball valves can be divided into straight through, three-way, and four-way according to their channel positions. The latter two types of ball valves are used for distributing media and changing the flow direction of media, and can also exchange media with each other. Ball valves can be divided into floating ball valves and fixed ball valves according to their structural forms; According to the channel, it can be divided into straight through, three-way, and four-way channels, and three-way channels can be further divided into T-shaped and L-shaped channels. According to the connection form, <a href="https://www.1ballvalves.com">Ball Valve</a></li>it can be divided into threaded (internal thread and external thread) connection, flange connection and welding type, and clamp type. According to the size of the ball passage of the ball valve, it can be divided into full bore and reduced bore. The diameter of the ball passage is called full bore, which is the same as the nominal diameter of the valve. If the diameter of the ball passage is smaller than the nominal diameter, it is called reduced bore ball valve; According to the different driving forces for opening and closing, ball valves can also be divided into electric ball valves, pneumatic ball valves, hydraulic ball valves, manual ball valves, etc. Due to the diversity of material selection, ball valves are also more widely used.
