What is the difference between mini water valve and mini air valve

Working principle

Both micro solenoid water valves and micro solenoid air valves rely on the magnetic force of electromagnets to control the opening and closing of the valves. However, due to different working media, they differ in specific working principles. The mini solenoid water valve controls the movement of the valve core by changing the current direction of the electromagnet, thereby controlling the flow of water. The dc solenoid valve controls the opening and closing of the valve by changing the current intensity of the electromagnet to control the circulation of air.

Working medium

The working medium of the dc micro solenoid water valve is water, while the working medium of the miniature solenoid air valve is air. Due to different working media, different factors need to be considered in their design and use. For example, water has high conductivity, so the coil design of the mini dc water valve needs to take into account moisture-proof and waterproof issues. The conductivity of air is poor, so the solenoid valve can pay more attention to the volume and weight issues in the design.

Application areas

Micro solenoid water valves are mainly used in water supply and drainage systems, cooling systems, heating systems and other fields to control the flow and pressure of water. Micro solenoid valves are mainly used in air compressors, gas transmission pipelines, pneumatic actuators and other fields to control the flow and pressure of gas.

Advantages and Disadvantages

The advantages of micro solenoid water valves include small size, fast response, precise control, etc., and because its working medium is water, it has advantages in certain specific application scenarios, such as food processing and pharmaceutical manufacturing and other places that require high cleanliness. However, due to the conductivity of water, solenoid water valves require more effort in moisture-proof and waterproof design. In addition, since the specific gravity of water is greater than that of air, the mini electric water valve may require more power to drive under the same volume.

The advantage of mini air control valve is that it can quickly respond and control the flow and pressure of gas, and is suitable for gas pipeline systems that require quick response and precise control. In addition, because its working medium is air, it has advantages in some application scenarios that require lightweight and portability. However, since the specific gravity of air is greater than that of water, the miniature solenoid air valve may require more space to install under the same volume, and due to the poor conductivity of air, it may not provide as precise control as the solenoid water valve.
