鉻鉬鋼截止閥主要用于化工設(shè)備、通用零部件、工業(yè)設(shè)備、制藥設(shè)備、通用設(shè)備、石化設(shè)備、電力設(shè)備、治金粉末設(shè)備、采礦設(shè)備，市政、電子工業(yè)等。適用介質(zhì) 水、蒸汽、油品、硝酸、醋酸、堿液、鹽水、海水、氧氣等。
J41Y鉻鉬鋼截止閥產(chǎn)品優(yōu)點(diǎn)：
1 在開(kāi)啟和關(guān)閉過(guò)程中，由于閥瓣與閥體密封面間的摩擦力比閘閥小，因而耐磨．
2 開(kāi)啟高度一般僅為閥座通道直徑的l / 4 ，因此比閘閥小得多。
3 通常在閥體和閥瓣上只有一個(gè)密封面，因而制造工藝性比較好，便于維修。但是，截止閥的缺點(diǎn)也是不容忽視的。其缺點(diǎn)主要是流阻系數(shù)比較大，因此造成壓力損失，特別是在液壓裝置中，這種壓力損失尤為明顯
