Structure characteristic:

  手(shǒu)動氣(qì)體切斷閥具(jù)有重量輕、結構新穎、耐磨損、流阻損失小、密封性強(qiáng)、自鎖性(xìng)可靠、操作靈活(huó)、指示方位明确(què)、維護方便、使用壽(shòu)命長等優點(diǎn)。可任意角度安裝，特别适用于調節切斷和要(yào)求快速自保的場合。配用蝸輪(lún)傳動裝置，可實現啟閉操作，是調節流量的理(lǐ)想設備。

  The valve has the features of lightweight, 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. It can be installed at any angle. It is 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.
