BSA1T英國斯派莎克波紋管截止閥可廣泛用于石油化工、電力、冶金、電子、真空、儀表、紡織等行業(yè)的水蒸汽、油品等非腐蝕性流體系統(tǒng)管路中。斯派莎克截止閥采用雙重組合密封，以雙層不銹鋼波紋管截止閥作為閥桿密封元件，同時以石墨填料作為二次輔助 密封，真正杜絕泄露。閥瓣與閥體之間采用經(jīng)精細研磨的錐面密封進一步確保了閥桿處動態(tài)和靜態(tài)密封性能的高度可靠，使其在各種工況下都表現(xiàn)出卓越的密封性能。BSA1T Spirax Sarco UK bellows globe valve can be widely used in petrochemical, electric power, metallurgy, electronics, vacuum, instrumentation, textile and other industries of water steam, oil and other non-corrosive fluid system piping. Spirax Sarco valves double combination sealed to double stainless steel bellows valve stem seal element as the same time as a secondary auxiliary graphite packing seal, stamp out the leak. Used between the valve and the valve body by fine grinding of conical valve stem seals further ensure the dynamic and static sealing performance at a highly reliable, so that in a variety of conditions have shown excellent sealing performance。

英國斯派莎克BSA1T波紋管截止閥采用獨特的波紋管密封設計，從而完全消除了閥桿填料密封泄漏的問題，滿足嚴格的泄漏等級要求。斯派莎克SpiraxSarco截止閥BSA型截止閥的零泄漏特性改善了設備的安全性，節(jié)約大量能源，減少了維修費用，并為工業(yè)應用提供了清潔安全的工作環(huán)境。
