一、產(chǎn)品簡(jiǎn)介：

 

波紋管截止閥的特性：1、雙重的密封設(shè)計(jì)(波紋管+填料)若波紋管失效，閥桿填料也會(huì)避免泄漏，并符合國(guó)際密封標(biāo)準(zhǔn)2、沒(méi)有流體損失，降低能源損失，提高工廠設(shè)備安全3、使用壽命長(zhǎng)，減少維修次數(shù)，降低經(jīng)營(yíng)成本4、堅(jiān)固耐用的波紋管密封設(shè)計(jì)，保證閥桿的零泄漏，提供無(wú)需維護(hù)的條件5、氣體介質(zhì)閥座采用PTFE軟密封材料提高本閥的密封性6、耐高溫≤425℃閥座采用錐面硬密封。達(dá)到氣密性能零泄漏二、產(chǎn)品技術(shù)參數(shù)
