Structure characteristic:

  輕(qing)型手動(dong)蝶閥，采(cai)用優質(zhi)碳素鋼(gang)焊接。具(ju)有重量(liang)輕、結構(gou)簡單、流(liu)阻損失(shi)小、操作(zuo)靈活、指(zhi)示方位(wei)明确、維(wei)護方便(bian)、使用壽(shou)命長、可(ke)任意安(an)裝等優(you)點。配用(yong)蝸輪⁉️傳(chuan)動裝置(zhi)切換☁️，開(kai)關輕松(song)自如,任(ren)意調節(jie)閥門開(kai)度,是調(diao)節流量(liang)的理想(xiang)設備。

  The valve is welded in fine carbon steel, having the features of light weight, compact structure, endurance, little in the lost of flow resistance, definite direction, easy to maintenance and long life. It can be installed at any angle. The valve is used with worm gearing device to form a complete set to realize switching freely and adjusting open angle of valve arbitrarily. It is the ideal equipment of adjusting flow.
