簡單介紹
WJ41H-16-DN15,WJ41H-16-DN20,WJ41H-16-DN25,WJ41H-16-DN32,WJ41H-16-DN40,德標(biāo)波紋管截止閥
德標(biāo)波紋管截止閥適用于公稱壓PN1.6-4.0MPa,工作溫度-20℃-350℃的石油、化工、制藥、化肥、電力工業(yè)等各種工況的管路上，切斷或接通管路介質(zhì)。
其主要結(jié)構(gòu)特點(diǎn)：
1、產(chǎn)品結(jié)構(gòu)合理、密封可靠、性能優(yōu)良、造型美觀；
2、密封面堆焊Co硬質(zhì)合金、耐磨、耐腐、抗磨擦性能好、使用壽命長；
3、閥桿調(diào)質(zhì)及表面氮化處理，有良好的抗腐和抗磨擦性能；
4、雙重密封，性能更可靠；
5、閥桿升降位置指示更直觀；
6、零件材料，法蘭和對焊尺寸可根據(jù)實際工況或用戶要求合理選配，滿足各種工程需要。
