What is the difference between solenoid valve 12v and 24v?How to choose the voltage.

A solenoid valve is a device that converts electrical energy into mechanical energy, using electromagnets to control the flow of liquid or gas in a pipeline. Solenoid valves are often classified into different types based on their input voltage, with 12V and 24V being two common voltages. So, what is the difference between solenoid valve 12V and 24V?
Input voltage
The input voltage of the 12V solenoid valve is 12V DC power supply, while the input voltage of the 24V solenoid valve is 24V DC power supply. Depending on the application environment and desired control requirements, it is important to select the proper voltage.
Application Scenario
Solenoid valves 12V are typically used in applications requiring low power consumption, such as small gas or liquid control systems. The 24V solenoid valve is more suitable for applications that require large flow control, such as industrial automation control systems or large agricultural equipment. Therefore, when selecting a solenoid valve, application requirements must be considered.
Solenoid Efficiency
Solenoid valves 12V and 24V will also differ in solenoid efficiency. Because in the same application environment, for the same electric power, the solenoid valve 12V will use a larger current to generate an electromagnetic field. This can lead to loss and heating of the electromagnets, reducing the efficiency of the device. Compared with this, the solenoid valve 24V requires less current to provide the same magnetic field, thereby reducing power consumption and heat generation.
Applicable power range
Different types of solenoid valves have unique requirements on the voltage and frequency of the input power supply. Solenoid valves 12V and 24V will also differ in this regard. If the wrong power supply is used, the solenoid valve may be damaged, resulting in equipment failure. Therefore, when purchasing a solenoid valve, make sure its power requirements match your application environment and control system.
Price
Price is also a point of difference between solenoid valves 12V and 24V. Since 12V solenoid valves are less expensive to design and produce, they may be less expensive than 24V solenoid valves. However, this also depends on the model and manufacturer.
