Six selection methods and essentials of solenoid valves on the market

1. Select the solenoid valve according to the pipeline parameters: diameter specification (namely DN), interface mode

2. Choose solenoid valve according to fluid

3. Choose solenoid valve according to pressure parameters: principle and structure variety

4. Electrical selection: AC220V and DC24 should be preferred for voltage specifications as much as possible.

5. Choose according to the length of continuous working time: normally closed, normally open, or continuously energized

6. Select auxiliary functions according to environmental requirements: explosion-proof, non-return, manual, waterproof, mist, water shower, diving

(1). Explosive environment: solenoid valves with corresponding explosion-proof grade must be selected.

(2). When the fluid in the pipe has backflow phenomenon, the solenoid valve with check function can be selected.

(3). When the solenoid valve needs to be operated manually on site, the solenoid valve with manual function can be selected.

(4). Waterproof and dustproof varieties should be selected for outdoor installation or dusty occasions (protection level above IP54).

(5). For fountains, submersible solenoid valves must be used (protection level above IP68).
