          磁力聯動裝置,UL認證
          V7系列Flotect流量開關是一種廉價的流量開關,可與兼容液體一起使用,在出現流動或無流動情況時啟動或停止電子操作設備。設計為標準防風雨設計,符合NEMA 4X。
          產品應用
          當通過加熱線圈的氣流發生故障時,鍋爐流量的證明會關閉燃燒器保護泵、電機和其他設備,防止低流量或無流量液體冷卻發動機,當冷卻液流動中斷時的機器和處理
          特點
          磁力驅動開關設計提供了優越的性能
          具有一個自由擺動的葉片,它吸引了固體金屬開關體內的磁鐵,通過一個簡單的杠桿臂驅動一個速動開關,沒有波紋管、彈簧或密封件失效
          下閥體是實體加工的確保無泄漏點的金屬棒料,無論機組運行多長時間
          堅固的葉片設計是剛性的,并且可在現場調節設定值
