In petrochemical, natural gas transportation, coal mining, pharmaceutical workshops, and dusty industrial environments, flammable and explosive gases, vapors, or dust may be present in the air, either continuously or intermittently.
On a millisecond timescale, the vehicle air flow solenoid valve coil must quickly generate sufficient magnetic force to move the valve core, thereby opening or closing the airway.
Impedance mismatch can cause electromagnetic interference (EMI) to radiate or conduct, disrupting the normal operation of other devices.
Explosion-proof coils utilize a multi-faceted approach, including flameproof housings, intrinsically safe circuitry, temperature rise control, high-quality sealing.
Insulation treatment uses a dipping or coating process to evenly cover the surface of the inductance coil with insulating paint, film, and other materials to form a dense protective layer.
The explosion proof coil's ability to maintain stable, heat-free operation for extended periods in high-risk environments is due to multiple technical optimizations in materials
