進口帶手動控制電磁閥
進口帶手動控制電磁閥產品概述
美國WORK,手柄開關可以在電磁閥線圈無電或燒壞時,實現(xiàn)電磁閥打開或關閉,適用于空氣、水、熱水、煤氣天然氣、柴油等管路的控制系統(tǒng);廣泛應用于、航天、船舶重工、核工業(yè)、石化、電力、化學、輕工、機械、科研、干燥設備、鍋爐、給排水、消防、食品、醫(yī)療、清洗設備、管道介質自動化控制等領域。
工作原理:
技術參數(shù):http://www.zy139。。com/cn/products/732.htm
常開式:閥自動控制時,手動柄必須處于打開狀態(tài);線圈失電后,旋轉手動柄可控制閥開關。
常閉型:閥自動控制時,手動柄必須處于關閉狀態(tài);線圈失電后,旋轉手動柄可控制閥開關。
產品特點:
電磁閥線圈失電或燒毀時,可用手動柄實現(xiàn)電磁閥打開和關閉;
