Operational principle; The Electric Ball Valve has a rotation of 90 degrees, the plug body is a ball, with a circular through-hole or channel through its axis. Ball Valve Electric in the pipeline is mainly used in the line to do the electric ball valve cut off, distribution and change the flow direction of the medium, it only needs to rotate 90 degrees of operation and a very small rotating torque can close tightly. Ball valve is most suitable for switching and cut off valve, It has been designed to throttle and control flow, such as V-type ball valve. The main characteristics of the electric ball valve itself is compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and sphere are often closed state, not easy to be eroded by medium, easy to operate and maintenance, suitable for water, solvent, acid and natural gas and other general working medium, but also suitable for poor working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, is widely used in various industries. Ball valve body can be integral or combined.
Principle: Electric ball valve is a combination of plug type ball valve and electric actuator, ball valve body structure is rotating 90 degrees spool, electric actuator to input 0-10 mah standard signal, electric unit drives the gear worm wheel worm corner torque, to adjust the valve with the switch box. Its use is mainly generated by electric flow rate and regulation operation.
Form: Commonly used electric actuators have multi-swing, single swing, intelligent, angular stroke actuator, direct stroke electric actuator, explosion-proof actuator, fine small actuator, etc. The ball valve mainly has Flange Ball Valve, fixed ball valve, O ball valve, V ball valve, three-way ball valve,Union Ball Valve, etc. Its execution and Electric Control Ball Valve configuration together to produce a variety of products. It can also add control box as a remote operation, adding other accessories on the actuator can achieve more functional applications, such as adding electrical positioning ator can be flow adjustment, resistance / current valve position converter can be used to indicate and control the valve position opening, hand wheel mechanism for manual operation when no current, commonly used other accessories and insulation sleeve, explosion-proof stroke switch, etc. The initial type selection can be selected according to the working conditions.
Apply: Electric ball valve has now been widely used in oil, natural gas, medicine, food, hydropower, nuclear power, electric power, water supply and drainage, heating, metallurgy and other industries, is a crucial mechanical product of national defense construction. It is also an indispensable product for the construction of science and technology. It occupies a lot of market share, mainly because the electric ball valve function, small size, reliable, large circulation capacity, light cheap, remote control and other reasons, Electric Valve is not only throttling, cut off, cut off, cut off, flow good products, or the first choice in the flow regulation system. It has pressure resistance, temperature resistance, corrosion resistance, small flow resistance, long service life, wide application range and other characteristics.
