對夾連接球閥具有結(jié)構(gòu)緊湊、體積小、重量輕、 密封性能好、啟閉靈活、安裝方便等特點。主要適用于石油、化工、冶金、制藥、食品等各類系統(tǒng)中。
而保溫對夾連接球閥良好的保溫保冷特性既能有效防止管路中粘稠介質(zhì)凝固,又能降低管路中介質(zhì)熱量的損失。
本系列對夾球閥可裝上相應(yīng)的電動及氣動裝置,以實現(xiàn)遙控或自動控制。
Features
The double-clip connected ball valve possess such features as compact structure, smaller volume, lighter ponderance, fine sealing performance,flexible on-off, convenient installation course, etc.
The heating double-clip connected ball valve enjoys favorable heat/cold preservation performances which not only effectively prevent the slabby medium in pipelines from solidifying but also reduce the heat loss of the medium in pipelines.
The double-clip connected ball valve series could also be applied with the mounted corresponding motor or air operated plant to implement remote control or automatic control.
