保能高溫蝶閥系環保節能型產品，能充分利用熱能有效治理煙氣。適用于建材、玻璃、礦山、電力等行業的熱風管道系統中。對管道中氣體介質按不同控制信號調節流量大小和切斷。

  This valve is the product of saving energy and environment protection which can administer smoke availably by using heat energy. It is widely used in the pipe system of hot wind in building material, glass, mining and power 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:

  保能高溫蝶閥，采用度熱強鋼、不銹鋼、優質碳鋼焊接，內襯熱強鋼及保溫材料層。具有耐高溫、耐磨損、剛性強、流阻損失小、熱損失小、保溫效率高、操作靈活、指示方位明確、維護方便、使用壽命長等優點。可水平安裝或垂直安裝。配用DKJ、ZKJ、伯納德等電動執行器及有關配件，可實現手動、自動無干擾切換，微機程控、自動控制或集中控制，是實現自動化控制操作、調節流量的理想設備。

  The valve is welded in high strength heat-resistant steel, stainless steel and fine carbon steel, having stainless steel lining and preserving heat material layer. It is high-temperature resistance, high in strength, endurance, little in the lost of the thermal energy and flow resistance, efficient in saving thermal energy, handy to operate, definite direction, easy to maintenance and long life. It can be installed in horizontal or vertical. 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.
