1, corrosive media: the use of plastic king solenoid valve and all stainless steel, for strong corrosion of the medium must be selected isolation diaphragm type. Neutral Medium, also should choose the copper alloy as the valve shell material solenoid valve, otherwise, the valve shell often has the rust chip to fall off, especially the action is not frequent occasions.
Ammonia valves are not available with copper.
2, explosive environment: must choose the corresponding explosion-proof grade products, open-air installation or dust multi-occasions should choose waterproof, dustproof varieties.
3, solenoid valve nominal pressure should exceed the maximum working pressure in the pipe.
