Hydraulic Solenoid Coil Construction Machinery Accessories Solenoid Coil Hole 20mm Height 52mm

Solenoid valve coil as the core component of solenoid valve, although its structure is simple but vital. It is mainly formed by wires wrapped around the insulation skeleton, and these wires are usually made of high-temperature and corrosion-resistant alloy materials to ensure stable work under harsh conditions. When the external current passes through the coil, according to the principle of electromagnetic induction, the coil will generate a magnetic field, which is strong enough to attract or repel the iron core (or valve core) inside the solenoid valve, thereby changing the switching state of the valve. The working mechanism of the solenoid valve coil is based on the conversion of the electromagnetic force, and the precise control of the fluid medium is realized. In addition, the number of turns of the coil, the diameter of the wire and the choice of insulation materials will directly affect the electromagnetic performance and service life of the coil.
