                                                                                                                                  膜片設計可防氣蝕、防腐蝕,并確保流速平穩,不受湍流和噪音干擾。

                                                                                                                                  頂部安裝設計方便拆裝和排除故障,使維護更簡單。

                                                                                                                                  可垂直或水平安裝。

                                                                                                                                  外部操作可以不用開開任何閥蓋就可以對閥門進行設置。

                                                                                                                                  多種涂層材料可選,可抗海水、鹽水或其他粗糙的流體介質,從而為閥門提供更好的保護。

                                                                                                                                  進口海水閥門工作原理:

                                                                                                                                  將介質從閥前引到膜片上方的腔室內,通過介質自身壓緊膜片將閥關閉,一旦介質從腔室中抽走, 膜片反彈,閥前介質直接頂開膜片,流體通過閥體進入閥后回路,整個過程可通過電動/氣動/液壓執 行機構實現自動操作。
