Solenoid valve is an industrial equipment controlled by electromagnetic, which is used to control the automatic basic components of the fluid and belongs to the actuator. Explosion-proof solenoid valve is to close all the parts of the equipment that may ignite the explosive gas mixture in a shell. The shell can withstand any joint surface or structural gap through the shell, and the combustible mixture that penetrates into the inside of the shell will explode inside without damage. In this article, ATO automation will introduce the 4 advantages of explosion proof solenoid valve.
