A solenoid valve is an electromechanical device used to control the flow of liquids and gases in industrial and automation processes. Understanding what is solenoid valve, what does a solenoid valve do, and how does a solenoid valve work is essential for engineers and technicians managing fluid systems.

What Does a Solenoid Valve Do? Common Uses

Solenoid valves act as electrically controlled switches for fluids. Main functions include:

• Opening and closing flow paths for liquids and gases

• Mixing or diverting media in pipelines

• Controlling pressure and flow direction

Typical applications:

• Refrigeration systems – reversing refrigerant flow for seasonal cooling and heating

• Irrigation systems – automated sprinklers and irrigation

• Medical and laboratory equipment – precise fluid dosing

• Industrial cleaning and manufacturing lines – controlling pneumatic or hydraulic actuators

How Does a Solenoid Valve Work?

To understand how does a solenoid valve work:

1. Electrical Coil Activation – current energises the coil, creating a magnetic field. (Burkerts New Coil)

2. Plunger Movement – magnetic force moves a plunger to open or close the valve.

3. Flow Control –

   • Normally closed (NC) valves open when energised.

   • Normally open (NO) valves close when energised.

4. Return to Default – a spring returns the plunger when power is removed.

Types of Solenoid Valves

Direct-Acting Solenoid Valves
Operate directly via the magnetic field. Ideal for low-pressure systems. View products.

Pilot-Operated Solenoid Valves
Use system pressure and magnetic force for higher flows. View products.

Applications: What Does a Solenoid Valve Do in Real Systems

• Home Appliances – control water intake

• Agriculture – automated irrigation and sprinklers

• HVAC/Refrigeration – regulate refrigerant flow

• Industrial Automation – actuate pneumatic cylinders and robotics (Browse solenoid valves)

• Medical Equipment – precise fluid delivery

Conclusion: Why Solenoid Valves Matter
