An electromagnetic valve (solenoid valve) that allows for precise control of the opening degree, rather than just on-off operation.
A proportional solenoid valve is an electromagnetic valve that can take any degree of opening, rather than a general-purpose on-off valve that cannot achieve high-precision control. For example, if you want to control pressure with an on-off solenoid valve, you would need to operate the valve as follows: - When the fluid pressure exceeds the set pressure: close the on-off solenoid valve - When the fluid pressure drops below the set pressure: open the on-off solenoid valve This method allows for a range of pressure control around the set pressure, but it cannot control a single point of pressure. However, by combining a proportional solenoid valve with a pressure gauge, a pressure control loop is completed, enabling high-precision pressure control. Additionally, when combined with a flow meter, it becomes a flow control valve, and when combined with a thermometer, it becomes a temperature control valve. By simply combining with various sensors, local control can be easily achieved.
