Description of six types of explosion-proof solenoid valve coils

The selection of explosion-proof electromagnetic coils should first follow the four principles of safety, reliability, applicability and economy, followed by the on-site conditions of six aspects (ie, pipeline parameters, fluid parameters, pressure parameters, electrical parameters, and operating modes). , special requirements to choose). Selection basis:

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

2. Select the solenoid valve according to the fluid parameters: material, temperature group

3. Select the solenoid valve according to the pressure parameters: principle and structure

4, electrical selection: voltage specifications should be preferred to use AC220V, DC24 is more convenient.

5, according to the length of continuous working time to choose: normally closed, normally open, or sustainable power

6. Select auxiliary functions according to environmental requirements: explosion-proof, check-out, manual, waterproof fog, water shower, diving
