Under normal circumstances, when selecting the electromagnetic valve of the pump valve fitting, four basic principles should be followed: safety, reliability, applicability and economy. At the same time on the basis of the four principles, followed by six aspects of field conditions to determine the next step in the selection, then let's share the six valve based on the selection of solenoid valve valve accessories.
In fact, with respect to the selection of solenoid valve fittings for pump valves, the six basic criteria to be referenced are: pipeline parameters, fluid parameters, pressure parameters, electrical parameters, action methods, and special requirements. The first is to select the size and interface of the solenoid valve according to the pipeline parameters. The second is to select the material and temperature group of the solenoid valve according to the fluid parameters.
The next step is to select the working pressure and structure of the electromagnetic valve of the pump valve fitting with reference to the pressure parameter, and then the electrical selection. It is more convenient to select the AC220V, DC24 as far as possible for the voltage specification thereof. The fifth point is to select normally closed, normally open, or sustainable power based on the duration of continuous work. Finally, the auxiliary function of the solenoid valve of the pump valve fitting is determined according to the environmental requirements.http://www.dmgcastings.com/
