磁力聯(lián)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(xiàn)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(fā)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(fā)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*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(xiàn)場調節(jié)設定值
