Products Details

Electric flanged ball valve is a kind of valve that controls the opening and closing of the valve through an electric actuator, which is widely used in various industrial fields. The following is a detailed description of the electric flange ball valve:

Basic structure and working principle:

The main material of the electric flange ball valve is usually precision cast stainless steel or carbon steel, and the body structure is cast as a whole silica sol, which has good sealing performance and fire protection characteristics.
The ball inside the valve rotates 90 degrees to achieve full opening or full closing, which is controlled by the electric actuator, so as to achieve remote control and automatic operation of the valve.
Main features:

Small fluid resistance: Ball valve is one of the least fluid resistance in all valve classes, even if it is a reduced diameter ball valve, its fluid resistance is quite small.
Good sealing performance: The sealing ring made of polytetrafluoroethylene and other elastic materials, the structure is easy to seal, and with the increase of medium pressure, the sealing ability is enhanced.
The valve stem seal is reliable: because the valve stem only rotates without lifting, the packing seal of the valve stem is not easy to break, and the sealing capacity increases with the pressure of the medium.
Long service life: Because polytetrafluoroethylene and other materials have good self-lubrication, the friction loss with the ball is small, so the service life of the ball valve is long.
Application field:

Electric flange ball valve is suitable for water, solvents, acids and natural gas and other general working media, but also suitable for poor working conditions of the media, such as oxygen, hydrogen peroxide, methane and ethylene.
Widely used in petroleum, chemical industry, metallurgy, light industry, paper making, power station, refrigeration and other fields of work.
Technical parameters:

Nominal diameter range: DN15-DN300.
Nominal pressure: PN1.6, 2.5, 4.0, 6.4, 10.0 MPa; ANSI 150, 300, 600 LB.
Temperature range: -28℃ -300 ℃.
Electric actuator form: ordinary type, explosion-proof type, intelligent integration.
Installation and maintenance:

The flange design of the ball valve allows it to be easily installed and removed on the pipe for easy maintenance and repair.
When installing, it is necessary to place the electric device on the support with bolts and nuts, and ensure that the valve core shaft and the output shaft of the electric device are fixed.
Additional features:

The electric flange ball valve can cut off and flow the medium in the transportation pipeline of petroleum, chemical industry, paper making, metallurgy, sewage treatment, oil tanker and so on.
Electric actuator built-in servo system, no additional servo amplifier, input 4~20mA signal and 220V AC power supply can control the operation.
Product certification and quality:

Electric flanged ball valve products undergo a rigorous testing and quality control process that complies with industry standards and certifications such as ISO and SIL.
Through the above information, it can be seen that the electric flange ball valve plays an important role in industrial automation and control, and its excellent sealing performance, low fluid resistance and long service life make it the preferred valve for many application scenarios.
