Introduction the Electric butterfly valve

        Electric butterfly valve is suitable to the occasion to flow regulation. Due to the pressure loss of the butterfly valve in the pipe is relatively large, which is about three times the gate, so the choice of valve, should give full consideration to the piping system pressure loss, also should consider the robustness when closingplate under medium pressure pipeline. In addition, must also consider the resilient seat material at high temperatures under the operating temperature limit. Butterfly valve length and overall height of the structure is small, opening and closing speed, and has a good flow control characteristics, the structural principle of the butterfly valve suitable for production of large diameter valves.
      When asked to use flow control valve as the most important, thechoice is the right size and type of valve, so that appropriate,effective work. The center line butterfly valve usually, control and regulate the media in the throttle, mud, requiring a short length of the structure, opening and closing speed (1/4). Low cut-off(pressure difference), the recommended use butterfly. The double adjustment, reduced in channel, low noise, there is the phenomenon of cavitation and gasification, a small amount of leakage to the atmosphere, with abrasive media, you can use butterfly. 

Linear Guideway

     Special working conditions in the throttle, or require strict sealing, or badly worn, low-temperature (cryogenic) conditions using butterfly valve, seal with the adjustment three eccentric orspecial double eccentric butterfly valve device use a specially designed metal.
