高性能密閉蝶閥，普遍(biàn)适用(yòng)于建材、玻璃、礦山、電力、輕(qīng)工、造紙等(děng)行業的通風、環保工程等管道系統中。對管(guǎn)道中氣體介質按不同(tóng)控制信号調節流(liú)量大小和切斷。

  This valve is widely used in the pipe system such as venting and environment protection in building material, glass, mining, power, light industry and papermaking departments. It can change the flow and cut off gas medium in the pipe by the different control signal.

結構特點：

Structure characteristic:

  高(gāo)性能密閉(bì)蝶閥(fá)具有重量輕、結(jié)構緊湊、耐(nài)磨損、流阻損失小、工(gōng)作壓力高(gāo)、密封壓差大、操作靈活、指示方(fāng)位明确、維護方便、使用壽命長等優點(diǎn)。可任意角度安裝，特别适用(yòng)于調節切斷和要(yào)求快速自保的場(chǎng)合。配(pèi)用DKJ、ZKJ、伯納德等(děng)電(diàn)動執行器及有關配件，可實現手(shǒu)動、自動無幹擾切(qiē)換，微機程(chéng)控、自動控制或(huò)中央集中控制，是實現(xiàn)自動化控制操作、調節(jiē)流量的理想設備(bèi)。

  The valve has the features of lightweight, compact structure, endurance, little in the lost of flow resistance, high working pressure, 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 DKJ, ZKJ, Bernard electric actuator and other accessory to form a complete set to realize manual and automatic exchange without interference, micro-computer long-range control, automatic control or center concentrating control. It is the ideal equipment of realizing operation of automatic control and adjusting flow.
