進口自保持式電磁閥德國托克TOK品牌：進口自保持式電磁閥應用范圍：它廣泛應用于冶金、石化、制藥、煙草、食品醫療、城建環保、給排水、采暖空調、消防安全、科研、節能產業等各個領域。
產品特點：
此產品節能為雙線圈控制，一個線圈瞬間通電后關閉電源、閥打開，另一個線圈瞬間通電后關閉電源、閥關閉。可以長時間保持關閉或打開狀態，能使線圈壽命更長。在高溫管道中使用*。
主要技術參數：

工作原理：
A：當電磁閥2號線圈瞬間通電后斷電，電磁閥打開。
B：當電磁閥1號線圈瞬間通電后斷電，電磁閥關閉。
規格尺寸：

Applications: 
It is widely used in metallurgy, petrochemical, pharmaceutical, tobacco, food and medical care, urban construction and environmental protection, drainage, heating and air conditioning, fire safety, scientific research, energy industry and other fields.
Features: 
This product is energy-saving control for the double coil, a coil is energized momentarily and then shut the valve to open, and the other coil instantly after power off, the valve closed.  Can long remain closed or open, to make the coil longer life. In the high temperature pipeline using the best.
Main technical parameters:

How it works: 
A: When the solenoid valve on the 2nd instant after power off the coil, the electromagnetic valve is opened. 
B: When the moment of the solenoid valve coil 1 after power off, the electromagnetic valve is closed.
