Dwyer 蝶閥 BFV系列

產(chǎn)品特色

兩通或三通；閥門(mén)口徑：50~406mm；多種型號(hào)可選；閥板具有較強(qiáng)抗腐蝕性；承壓10.3bar，耐溫107℃

BFV 系列蝶閥的最重要的特征是它采用了筒式閥座代替了經(jīng)常出現(xiàn)安裝問(wèn)題的燕尾閥座。它的扭矩更低且更加協(xié)調(diào)。精密的閥瓣和閥體制造工藝使得閥瓣和閥座之間緊密配合，法蘭和閥瓣閥座之間各自獨(dú)立。有圓盤(pán)式和外耳法蘭式的，帶10段定位鎖定手柄。標(biāo)準(zhǔn)選項(xiàng)的閥門(mén)可承受225psi(15.5 Bar),滿足MSS-SP-67和API-609的要求。
