RC series stainless steel flange electric ball valve is a rotating ball valve with the angle range from 0 degree to 90 degree, which presents good seal performance, large flow capacity, small flow resistance coefficient, simple structure, convenient maintenance, long service life. The channel of the body and the connecting pipe has the equal diameter to be connected together, which allows medium to flow almost no loss. The RC series valves are usually used in the occasion of high sealing performance requirements to control not only the medium of gas, liquid, but also the medium of sewage and fibrous impurity medium, which is widely applied in the fields of petroleum, chemical, metallurgy, light industry, papermaking, power station, refrigeration and so on.
The working principle of electric ball valves: electric actuators drive the stem to rotate together with the ball with a hole (or part of the ball) to realize the valve switch. The valve can open and close fully by rotating 0-90 °. Compared with the same specifications of the gate valve and globe valve, the ball valve is smaller, lighter and easier installation in pipeline.
