不銹鋼硬密封球閥產(chǎn)品結(jié)構(gòu)特點(diǎn)Construction Features

不銹鋼硬密封球閥經(jīng)過特殊工藝處理的球體與閥座，特別適用于較高溫度及含各種粉塵與固體顆粒的介質(zhì)。
1、采用特別設(shè)計(jì)的補(bǔ)償性可動(dòng)金屬閥座結(jié)構(gòu)，密封可靠。
2、本系列球閥應(yīng)按規(guī)定流向使用。
3、本系列球閥可配多種驅(qū)動(dòng)裝置。

process through special techniques, the globe body and valve seat are especially applicable for high-temperatures and the medium containing dusts and solid particles.
1.The specially-designed compensatory movable valve seat construction made from metal is of great reliability in its sealing performance.
2.The ball valve series should be applied in accordance to the specified flow direction.
3.Multiple driving devices could be prepared for the series.
