Safety of Explosion-Proof Solenoid Valve
Due to the particularity of the working environment, Explosion-Proof Solenoid Valve products may have a certain explosion hazard if accidents occur. Therefore, the production of explosion-proof solenoid valve products not only pays special attention to safety, but also needs to reach a certain explosion-proof level and production qualification. The safety of explosion-proof solenoid valve products includes the internal safety of the medium and the solenoid valve, and the external safety of the working environment.
The internal safety of the explosion-proof solenoid valve---media properties, working pressure, etc.
1. Corrosive medium: Plastic solenoid valve and all stainless steel should be used; for strong corrosive medium, the isolation diaphragm type must be used.
2. The nominal pressure of the Explosion-Proof Valve should exceed the highest working pressure in the pipe.

the external safety of the explosion-proof solenoid valve --- working environment
1. The maximum and minimum temperature of the environment should be selected within the allowable range. If there is any out of tolerance, a special order should be made.
2. In the environment where the relative humidity is high and there are water drops and rain, etc., a waterproof solenoid valve should be selected.
3. In the environment where there are frequent vibrations, bumps and impacts, special varieties should be selected, such as marine solenoid valves.
4. For use in corrosive or explosive environments, corrosion resistance should be selected according to safety requirements first
5. If the environmental space is restricted, please use the multifunctional solenoid valve, because it saves the bypass and three manual valves and is convenient for online maintenance.
6. Explosive environment: products of corresponding explosion-proof grade must be selected, and waterproof and dust-proof products should be selected for outdoor installation or dusty places.
Explosion-proof solenoid valve products belong to a special category of solenoid valves. The production of such solenoid valve products requires an explosion-proof solenoid valve production qualification. The relevant unit has been audited and determined that the manufacturer has the qualification to produce the Solenoid Valve product and guarantees certain quality Only with high quality level can the corresponding explosion-proof solenoid valve production license be issued.
