手動翻(fan)闆式三杆(gan)蝶閥，廣泛(fan)适用于建(jian)材、玻璃、礦(kuang)山、電力👅、輕(qing)工、造紙等(deng)行業的能(neng)源輸送管(guan)道的煤氣(qi)、天然氣、通(tong)風、環保工(gong)程等管道(dao)系統中。對(dui)管道中氣(qi)體介質按(an)不同控制(zhi)信号😄調節(jie)流👌量大小(xiao)🙇‍♀️和切斷。

  This valve is widely used in the pipe system transporting coal gas, natural gas, venting and environment protection in building material, glass, mining, power, light industry and papermaking departments. The technique is introduced from foreign Company. It can change the flow and cut off gas medium in the pipe by the different control signal.

  The valve has the features of compact structure, endurance, little in the lost of flow resistance, good seal, reliable self-locking, flexible operation, definite direction, easy to maintenance and long life. The seal of driving shaft is out seal, which is easy to be adjusted and changed without stopping, so the out leakage is avoided effectively. All kinds of seal type can suit different medium. It is especially suitable in the condition of adjusting, cutting off and self-protecting quickly. The valve is used with worm gear driving device to form a complete set to realize open-close operation. It is the ideal equipment of adjusting flow.
