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.
