J941H電動硬密封截止閥概述： 
電動截止閥的啟閉件是塞形的閥瓣，密封面呈平面或錐面，閥瓣沿流體的中心線作直線運(yùn)動。閥桿的運(yùn)動形式，有升降桿式（閥桿升降，手輪不升降），也有升降旋轉(zhuǎn)桿式（手輪與閥桿一起旋轉(zhuǎn)升降，螺母設(shè)在閥體上）。截止閥只適用于全開和全關(guān)，不允許作調(diào)節(jié)和節(jié)流。
J941H電動硬密封截止閥結(jié)構(gòu)特點(diǎn)與用途： 
1.可以安裝在管道的任何位置上，介質(zhì)從下往上流。 
2.不銹鋼截止閥適用于各類腐蝕性介質(zhì)的管道上，有良好的防腐性、足夠的強(qiáng)度。 
3.合金鋼截止閥適用于耐高溫的蒸汽、油品管道上，具有耐高溫特點(diǎn)。
