1. Corrosive media: Plastic King solenoid valves and all stainless steel should be used; for strongly corrosive media, isolation diaphragm type must be used. For neutral media, it is also suitable to use copper alloy as the valve material of the solenoid valve. Otherwise, rust may often fall off in the valve housing, especially in occasions where the action is not frequent. Valves for ammonia cannot be made of copper.
2. Explosive environment: corresponding explosion-proof products must be selected. Waterproof and dustproof varieties should be selected for outdoor installation or dusty occasions.
3. The nominal pressure of the solenoid valve should exceed the maximum working pressure in the pipe.
