產(chǎn)品特點(diǎn)
1、本閥采用三偏心密封結(jié)構(gòu)，閥座與蝶板磨損小。
2、密封圈選用不銹鋼制作，具有金屬硬密封和彈性密封的雙重優(yōu)點(diǎn)，無論在低溫和高溫的情況下，均具有優(yōu)良的密封性能，具有耐腐蝕,使用壽命長等特點(diǎn)。
3、碟板密封面采用堆焊鈷基硬質(zhì)合金，密封面耐磨損，使用壽命長．
4、大規(guī)格蝶板采用絎架結(jié)構(gòu)，強(qiáng)度高，過流面積大，流阻小。
5、本閥具有雙向密封功能，安裝時(shí)不受介質(zhì)流向的限制，也不受空間位置的影響，可在任何方向安裝。
6、驅(qū)動(dòng)裝置可以多工位（旋轉(zhuǎn)90°或180°）安裝，便于用戶使用。
