一、Q41F不銹鋼浮動球閥產(chǎn)品概述
Q41F不銹鋼浮動球閥聚多年球閥制造經(jīng)驗而設(shè)計的閥座，確保閥門密封，磨擦系數(shù)低，操作力矩小、多種閥座材料、適應(yīng)范圍廣；該閥采用扁頭閥桿，與手柄的連接不會錯位，從而保證手柄指示的開關(guān)狀態(tài)與閥一致；Q41F不銹鋼浮動球閥為防止閥門開關(guān)誤操作，在閥門全開、全關(guān)位置有鎖定孔，確保閥門處于正確的位置；閥桿為下裝式，防止受壓飛出，同時可在火災(zāi)后，與閥體形成金屬接觸，確保閥桿密封。
Q41F不銹鋼浮動球閥適用于水、氣、油品、天然氣和酸堿腐蝕性介質(zhì)；適用溫度：-196～350℃，公稱通徑：DN 15-250mm，驅(qū)動方式：手動、氣動、電動、液動等。
