品牌：RETZ瑞茨/我們一直致力于流體控制領域的持續創新，始于2005……進口帶手動控制電磁閥的性能特點與其他電磁閥性能一樣，手柄開關可以在電磁閥線圈無電或燒壞時,實現手動打開或關閉電磁閥，主要用于消防系統安全防護，在各種常溫、中溫、常壓、中壓等場合的純凈氣體、液體、瓦斯、油品、蒸汽、熱水的管路自動控制The performance characteristics of RETZ with manual control solenoid valve are the same as those of other solenoid valves. The handle switch can manually open or close the solenoid valve when the solenoid valve coil is dead or burnt out. It is mainly used for fire protection system safety protection and automatic control of pure gas, liquid, gas, oil, steam, hot water pipelines in various normal temperature, medium temperature, atmospheric pressure, medium pressure and other occasions

進口帶手動控制電磁閥工作原理--Working principle of imported manual control solenoid valve

當自動控制時When under automatic control

常閉式-手動開關指向關：線圈通電，電磁閥打開；線圈斷電，電磁閥關閉 Normally closed - manual switch pointing to close: the coil is energized and the solenoid valve is opened; Coil power off, solenoid valve closed

常開式-手動開關向開的方向旋轉2~4圈，電磁閥不通電為打開狀態。當線圈通電時，閥關閉 Normally open - Rotate the manual switch in the open direction for 2-4 turns, and the solenoid valve is in the open state when it is not energized. When the coil is energized, the valve closes

當手動控制時 When manually controlled

旋轉手動開關，常閉式手動開關指向開的方向（常開式向開的方向旋轉2~4圈）電磁閥打開，介質流通；旋轉手動開關，常閉式手動開關指向關的方向（常開式向關的方向旋轉到不動為止）電磁閥關閉，介質截止。

Rotate the manual switch, the normally closed manual switch points towards the open direction (the normally open switch rotates 2-4 turns towards the open direction), and the solenoid valve opens, allowing the medium to flow; Rotate the manual switch, with the normally closed manual switch pointing towards the closed direction (the normally open switch rotates towards the closed direction until it remains stationary). The solenoid valve is closed and the medium is cut off.
