With further develpment of industiral automation, hydraulic and pneumatic control technology has been weidely used in various fields,. Explosion-proof solenoid valve is required in flammable and explosive environment.
The electromagnetic coil in the explosion-proof solenoid valve is bound to consume electric energy in the working process, causing heating and even being burned down in case of failure, which is the source of detonation. Therefore, wehn deigning the explosion-proof electromagnetic coil, the first thing to consider is that it should have reliable explosion-proof performance.
