What is a Solenoid Valve：Working Principle, Types and Applications
- DELCO Valve
A solenoid valve is a common valve assembly used to control flow in a fluid or pneumatic mechanical system. In this article, DELCO Valves will introduce you to this type of valve in many ways.
What is a Solenoid Valve
Solenoid valve is a device that controls the flow of fluid by electromagnetic force. It consists of a solenoid coil, an iron core, an iron core winding, a valve spool, a valve seat, a valve stem and so on. It controls the opening and closing of the valve by controlling the current of the solenoid coil, thus regulating the flow of fluid. They are often used in fluid control applications to control water, air, oil or gas.
How Does a Solenoid Valve Work?
When a solenoid coil is energized, it generates a magnetic field that pushes the valve stem to open or close the valve. They are classified as normally open (NO) and normally closed (NC) based on their default state when not energized.
Types of Solenoid Valve
- Step-by-step direct-acting type: widely used in water supply and drainage, petrochemical, electric power and other fields; suitable for medium and large caliber, working pressure zero to low pressure piping system.
- Direct-acting type: applicable to the miniaturization of the device and high-frequency action and other occasions.
- Pilot operated type: widely used in the flow and pressure requirements of the higher occasions, such as steam, high pressure water, oil and other media control.
Applications
- Control of liquid flow in hydraulic systems, such as hydraulic lifts, hydraulic cylinders;
- Application in air compressors for regulating gas flow;
- In water pumps for regulating water flow;
- For controlling fuel intake in diesel engines;
- Controlling the temperature of an air conditioning system, such as an air conditioning system, for controlling the temperature of the air conditioning system;
Conclusion
Solenoid valves are critical for reliable and efficient fluid control in various industries. By understanding their types, working principles, and applications, you can choose the right valve for your system.
