先導控制式二位二通隔膜閥
類型 0290 / ID 號碼 44373
產品描述
閥門 0290 是一款 S.EV 結構系列的先導控制式隔膜閥。閥門在無差壓時打開。透過隔膜和磁銜鐵的固定連接,為打開過程提供支援。在此過程中,整合的「Soft Kick」(軟擊)功能在打開時可以對材料起到保護作用。根據具體應用,可以提供不同的隔膜材料。不鏽鋼變體進一步完善了殼體的選材。電磁線圈包覆有一層化學耐抗性高的環氧樹脂。為了降低電能功耗,所有 DC 變種都在电磁线圈中安裝了一個「Kick and Drop」電子設備。與符合 DIN EN 175301-803 A 形的插頭配套使用時,閥門滿足 IP65 防護等級 – 配套使用一個不鏽鋼殼體 NEMA 4X。
