FAQs of Compact Flapper Solenoids

1. What is the function of flapper solenoids?

The main purpose of the flapping solenoid is to control the mechanical movement, air flow, gas flow, or liquid flow of industrial equipment. Flapper solenoids transform electrical energy into accurate mechanical motion by electromagnetic force. The typical applications are printing machines, medical equipment, automation systems, pneumatic control devices, fluid control systems, and smart industrial equipment. Due to their compact size, fast response, and switching performance, flapper solenoids are ideal for precise control.

2. How do the flapping solenoids work function well?

The flapping solenoids use the electromagnetic coil to generate magnetic force. The current that runs through the coil creates the magnetic field that attracts the internal armature. As a result, the movement of the armature controls the air flow, liquid flow or mechanical movement via the flapper. As soon as the power supply stops, the spring returns the flapper to the original position.

This simple electromagnetic process ensures quick switching performance.
