英國(guó)斯派莎克BSA系列波紋管密封截止閥采用的波紋管密封設(shè)計(jì)，從而消除了閥桿填料密封泄漏的問(wèn)題，滿足zui嚴(yán)格的泄漏等級(jí)要求。BSA型截止閥的零泄漏特性改善了設(shè)備的安全性，節(jié)約大量能源，減少了維修費(fèi)用，并為工業(yè)應(yīng)用提供了清潔安全的工作環(huán)境。
BSA型截止閥的口徑從DN15-DN250，可提供各種不同的材質(zhì),從鑄鐵材質(zhì)的BSA1，球墨鑄鐵的BSA2和鑄鋼材質(zhì)的BSA3型截止閥連接標(biāo)準(zhǔn)有法蘭，螺紋和承插焊接等，壓力等級(jí)可達(dá)PN40，ANSI 300和CLASS 800。zui高工作溫度可425C°,可用于高溫系統(tǒng).從而用一種閥即可滿足各種不同的工業(yè)應(yīng)用要求,并確保長(zhǎng)的使用壽命,免維修及堅(jiān)固結(jié)實(shí)。斯派莎克BSA系列截止閥應(yīng)用流體：
1、蒸汽和冷凝水
2、工藝流體
3、熱水和冷水系統(tǒng)
4、熱油系統(tǒng)
5、化學(xué)流體
6、毒性流體
7、壓縮空氣和其它氣體
8、水/乙二醇等工業(yè)流體
