Product Overview and Characteristics
Electric ball valves are part of rotary ball valves, which can be fully closed by rotating 90 degrees. Compared with gate valves and globe valves of the same specifications, ball valves are small in size, light in weight, powerful in function, high in reliability and easy to install in pipelines. It has excellent sealing performance, large circulation capacity, small flow resistance coefficient, simple structure, convenient maintenance and long service life. The valve body passage and connecting pipe are equal in diameter and have a constant diameter, and the medium can flow almost without loss. The product is usually used in the occasion of strict sealing requirements. In addition to controlling gas, liquid and steam media, it is also suitable for controlling sewage and media containing fibrous impurities. Ball valve is an important kind of valve, which is widely used in petrochemical industry and long-distance pipeline. Its closing part is a part of sphere with holes. The sphere rotates with the valve stem to open or close the valve. Flow direction can be arbitrary, adjustable in a wide range, can be used in high pressure and large caliber occasions, control high viscosity, with fibers and fine particles of media. BR series electric ball valves can be fully closed by rotating 90 degrees, compared with gate valves and globe valves of the same specifications.

Characteristic
The electric ball valve can cut off and flow the medium in the transportation pipeline of petroleum, chemical industry, papermaking, metallurgy, sewage treatment and tanker truck. It has excellent sealing performance, large circulation capacity, convenient handling and maintenance, small flow resistance, reliable sealing and even cut off. The electric valve has the advantages of small size, light weight, large thrust, strong function, built-in servo amplifier, convenient operation and high reliability. Flow direction can be arbitrary, adjustable in a wide range, can be used in high pressure and large caliber occasions, control high viscosity, with fibers and fine particles of media.
direct connect
The electric actuator has built-in servo system, which can be controlled by 4-20mA input and output signals and 3800VAC power supply without additional servo amplifier. The utility model has the advantages of simple connection, compact structure, stable and reliable movement, etc. Since its establishment, Yangzhou Bell Electric Valve has focused on the production of automated valves. Manual ball valves and electric ball valves are easy to control. The spheres have high temperature and wear resistant products such as stainless steel and ceramics. With this stage, the company has made a great leap forward, attracting some elites in technology, sales and management from other countries. As a result, the company has developed rapidly at home and abroad, and some products have been patented, which has won the favor of municipal and users and exported to Southeast Asia and Europe. Ball valve is a kind of valve which came out in the 1950s. In half a century, ball valve has developed into a major valve. Ball valves are mainly used for cutting off or connecting media, and also for regulating and controlling fluid. V-type ball valves can regulate and control flow accurately, while three-way ball valves are used to distribute media and change the flow direction of media.
Compared with other valves, ball valves have the following advantages
1. Fluid resistance is small. Ball valve is one of the lowest fluid resistance of all valves. Even for shrink ball valve, its fluid resistance is quite small.
2. The switch is fast and convenient. As long as the stem rotates 90 degrees, the ball valve will complete the full opening or closing action, and it is easy to achieve rapid opening and closing.
3. Good sealing performance. The sealing ring of ball valve seat is usually made of elastic materials such as PTFE, which is easy to ensure sealing, and the sealing force of ball valve increases with the increase of medium pressure.
4. Stem sealing is reliable. When the ball valve opens and closes, the stem only rotates, so the packing seal of the stem is not easy to be destroyed, and the sealing force of the reverse seal of the stem increases with the increase of medium pressure.
5. The opening and closing of the ball valve only rotates at 90 degrees, so it is easy to realize automatic control and long-distance control. The ball valve can be equipped with pneumatic device, electric device, hydraulic device, pneumatic-hydraulic device or electro-hydraulic device.
6. Ball valve channel is smooth and smooth, and it is not easy to deposit medium, so it can be used for pipeline through the ball. Nominal pressure or pressure level: PN1.0-32.0 MPa, ANSI CLASS 150-900, JIS10-20K nominal diameter or caliber: DN6-900, NPS 1/4-36 connection mode: flange, butt welding, threads, socket welding and other applicable temperatures: -196 ~540 C driving mode: manual, worm and worm drive, pneumatic, electric, hydraulic, pneumatic-hydraulic linkage, etc. Electro-hydraulic valve body materials: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti. Selection of different materials can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing media, urea and other media.
