  • Electric Power Plants: Reliable performance for switchgear operations and automated control systems.

Air Solenoid Valves

Air Solenoid Valves are electro-mechanical devices that regulate the flow of compressed air in pneumatic systems. When electrically activated, they open or close pathways to control air flow, pressure, or both.

How many types of pneumatic solenoid valves?

  • 2/2-Way Valves: Simple ON/OFF valves with one inlet and one outlet.
  • 3/2-Way Valves: Equipped with one inlet, one outlet, and one exhaust port.
  • 4/2-Way & 5/2-Way Valves: Used in more complex systems, offering additional ports for greater control.

How do I choose a pneumatic solenoid valve?

Key Factors to Consider

Application Requirements

  • Type of Medium: Is it just air, or are you dealing with other gases or fluids? The valve material and design may differ based on the medium.
  • Flow Rate: How much air or fluid needs to flow through the valve? A mismatch here can lead to inefficiency or malfunction.

Valve Type

  • 2/2-Way, 3/2-Way, or 5/2-Way: The number of ports and positions will depend on your specific application needs.

Operating Pressure

  • Pressure Range: Each valve comes with a specific operating pressure range. Make sure it matches your system’s requirements.

Power Supply

  • Voltage and Current: Choose a valve that is compatible with your electrical system.


  • Corrosion Resistance: Especially important in chemical or high-moisture environments.

What is the difference between pneumatic valve and solenoid valve?

Pneumatic Valves


  • What are they?: These are valves that are operated by compressed air.


  • How do they work?: Actuated by pneumatic pressure, generally from an air cylinder or similar pneumatic actuator.

Control Type

  • Manual or Automated: Can be either manually operated, or triggered by air pressure.


  • Simplicity: Generally less complex when it comes to electrical components.


  • Where are they used?: Suitable for larger-scale industrial applications where air supply is abundant, such as manufacturing plants, chemical plants, and more.


  • Versatility: Can be easily integrated into existing pneumatic systems.

Solenoid Valves


  • What are they?: These are electromechanically operated valves.


  • How do they work?: Actuated by an electrical coil, which creates a magnetic field when electrified.

Control Type

  • Automated: Generally automated, controlled by an electrical signal.


  • Intricacy: Involves more intricate electrical components and is often smaller in size.


  • Where are they used?: Commonly used in more compact systems or where electrical control is preferred, such as in medical equipment, household appliances, and automotive systems.


  • Precision: Offers higher precision in control, suitable for more delicate or complex tasks.
