波紋管截止閥
波紋管截止閥用途
波紋管截止閥適用于公稱壓力PN1.6～16MPa，工作溫度-29～350℃的石油、化工、制藥、化肥、電力行業(yè)等各種的工況上，卻斷或接通調(diào)節(jié)管路介質(zhì)
波紋管截止閥特點
1、產(chǎn)品結(jié)構(gòu)合理、密封可靠
2、密封面堆焊Co基硬質(zhì)合金，耐磨、耐腐、抗摩擦性能好、使用壽命長
3、閥桿調(diào)質(zhì)及表面氮化處理，有良好的抗腐和抗摩擦性能
4、零件材質(zhì)及法蘭、堆焊端尺寸可根據(jù)實際工況或用戶要求合理選配，滿足各種工程需要
5、閥芯可根據(jù)需要做承切斷型和調(diào)節(jié)型
