12V DC 1/2 inch Electric Solenoid Water Air Valve Switch (Normally Closed)

Description

1. Voltage: The solenoid valve operates on a 12-volt direct current (DC) power supply. It is crucial to provide the correct voltage to ensure proper operation.
2. Valve Size: The “1/2 inch” designation refers to the size of the valve’s inlet and outlet ports. In this case, the valve has 1/2-inch threaded ports, which are suitable for connecting to pipes or tubing with matching threads.
3. Normally Closed (NC): This solenoid valve is of the “normally closed” type. In its default state (when no power is applied), the valve is closed, blocking the flow of fluid. When a 12V DC electrical signal is applied, the valve’s solenoid coil activates, causing the valve to open and allowing the fluid to flow through.
4. Fluid Compatibility: It is important to ensure that the solenoid valve is compatible with the type of fluid you intend to control, whether it’s water, air, gas, or other compatible fluids. Some solenoid valves are specifically designed for water, while others are suitable for air or other gases.
5. Material: The construction material of the valve body and internal components can vary. Common materials include brass, stainless steel, and plastic. The choice of material should be based on the compatibility with the fluid and the intended application.
6. Pressure Rating: Solenoid valves are rated for a specific maximum pressure. It’s important to choose a valve with a pressure rating that matches or exceeds the pressure conditions in your system.
7. Temperature Range: Consider the temperature range in which the solenoid valve will operate. Different valves are designed for various temperature ranges, and choosing the appropriate one is essential to prevent damage or malfunction.
8. Coil Type: The solenoid coil can be available in various configurations, such as AC or DC voltage and different power ratings. Ensure that you select a valve with the correct coil type and voltage rating for your application.
9. Applications: Solenoid valves are used in a wide range of applications, including irrigation systems, water purification systems, pneumatic systems, automotive systems, and industrial automation.
10. Control: You can control the solenoid valve using an external 12V DC power source and an appropriate control circuit. This allows you to open and close the valve as needed in your application.
