Electric PLUG VALVES is closed or a plunger-shaped pieces of a rotary valve, the valve by rotating 90 degrees to the channel mouth stuffed with the body's openings on the same or separate, to achieve open or close a valve.
(1) Electric plug valve fluid through the DC resistance is small, easy to open and close quickly.
(2) Electric plug valve is the earliest history been used valves. As the structure is simple, open and close quickly (plug rotation 1/4Q ring opening and closing movements can be done), easy to operate, fluid resistance, which is still widely used. Currently used in low pressure, small caliber and medium temperature is not high in the case.
(3) Electric plug valve in the pipe is mainly used for cutting or change in media distribution and flow direction. It is easy to adapt to multi-channel structure, as well as a valve can be two, three, even four different flow channel, which can simplify the design of piping systems, reducing the amount of valve gate and the equipment needed to connect a number of accessories.
(4) According to the electric PLUG VALVES design of the structural features and functions that can be achieved, according to the following principles can be used.
