進口低溫防爆電磁閥作原理：

常閉：當線圈通電時，先導閥芯吸合，先導孔打開，閥上腔卸壓，活塞靠下腔介質壓力推動，電磁閥打開；當線圈斷電時，先導閥芯靠彈簧復位，先導孔關閉，閥腔由活塞節流孔增壓和復位彈簧的推力，電磁閥關閉。

Working principle of imported low temperature explosion-proof solenoid valve:

Normally closed: when the coil is energized, the pilot valve core is pulled in, the pilot hole is opened, the pressure in the upper chamber of the valve is relieved, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened; When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, the valve chamber is pressurized by the piston orifice and the thrust of the return spring, and the solenoid valve is closed.

Product introduction of imported low temperature explosion-proof solenoid valve:

The low-temperature explosion-proof solenoid valve imported from Germany de lock refers to the valve whose connecting terminal meets the electrical explosion-proof requirements to prevent the explosion of combustible and explosive gases. The valve core is made of low-temperature cryogenic treated stainless steel, the seal is made of special low-temperature resistant materials, and the minimum temperature can reach - 196 degrees. The valve switch is driven by a coil, which can realize the remote automatic control of low-temperature medium, It is applicable to the opening and closing of liquid nitrogen, liquid ammonia, liquid oxygen, liquid argon, liquefied natural gas, LNG and low-temperature refrigerant.
