Tips: Function of Explosion-proof Solenoid Valve
The coil shell of the explosion-proof solenoid valve not only has the flameproof effect under the pressure of gas explosion, but also has the blocking effect on the energy transfer of gas explosion, and the safety performance is higher. Is specially designed for the transmission of flammable and explosive medium or dedicated to explosive dangerous places of special solenoid valve series products, different environments and fluids should choose different grade of explosion-proof solenoid valve.
