EVR EVRA Refrigeration Valve 018F6261 BF230AS Cable Wire Solenoid Coil
The coil of the solenoid valve passes Faraday's law, and after the energization, magnetic lines of force are generated, and then the magnetic lines of force cause the two metals inside to attract each other, thereby generating an action. The solenoid coil is established by the presence of a magnetic field around the wire, and is wound into a spiral-shaped reinforcing magnetic field, that is, the minimum magnetic field is used to achieve the highest magnetic field strength, and the wire coated with a layer of insulating varnish is used instead of the ordinary wire to save space.
Electromagnetic forming can effectively improve the forming properties of lightweight alloys, and the coil structure is one of the key factors affecting the forming quality. It is necessary to determine the distribution of the electromagnetic force according to the needs of the deformation part of the workpiece and design a coil suitable for it.

Refrigeration solenoid valve working principle
When the coil is energized, the refrigerating solenoid valve forms a magnetic field, sucks up the iron core, and the pilot valve opens, so that the pressure acting on the upper part of the piston is lowered, thereby pushing the piston upwards by the pressure difference to make the pipeline unblocked; when the coil is de-energized, the iron is broken. The core drops due to its own weight and spring action to close the pilot valve. At the same time, the pressure medium flows into the upper chamber through the piston orifice, and the piston's own weight and spring pressure cause the piston to fall to the valve port, thereby cutting off the nozzle.
