Solenoid valve is an industrial equipment controlled by electromagnetic, which adjusts the direction, flow, speed and other parameters of the medium in the industrial control system.
When the
valv tas-solenojd is not powered on, the valve needle blocks the passage of the valve body under the action of the spring, and the solenoid valve is in the cut-off state. When the coil is powered on, the coil generates a magnetic force, the valve core is lifted up against the spring force, the channel in the valve is opened, and the solenoid valve is in a conducting state.
Solenoid valve classification
Solenoid valves at home and abroad are divided into three categories in principle (ie: direct-acting type, step-by-step direct-acting type, pilot-operated type), and they are divided into six types according to the difference in the structure and material of the valve disc and the difference in principle. Branch sub-categories (direct-acting diaphragm structure, step-by-step diaphragm structure, pilot-operated diaphragm structure, direct-acting piston structure, step-by-step piston structure, pilot piston structure).
