Pneumatic Solenoid Valves | 3-Way & 5-Port Air Control Valves

Control compressed air and gas with pneumatic solenoid valves designed for fast, reliable directional control. These electrically actuated air control valves are commonly used in industrial automation, pneumatic cylinders, manufacturing equipment, robotics, and other applications requiring precise control of compressed air.

Our pneumatic valves are available in 3-way, 2-position and 5-port (4-way), 2-position configurations with 24V DC and 110V AC coil options, making them suitable for a wide range of commercial, industrial, OEM, and compatible DIY pneumatic systems.

Why Choose a Pneumatic Solenoid Valve?

Pneumatic solenoid valves provide quick and dependable control of compressed air by using an electrical signal to shift airflow through the valve.

Benefits include:

• Fast response times
• Compact design for easy installation
• Durable construction for demanding environments
• Available in multiple valve configurations
• Standard NPT threaded ports
• 24V DC and 110V AC coil options
• Designed for compressed air and compatible gas control

Whether you're automating machinery, replacing an existing valve, or building a new pneumatic system, these valves provide dependable directional air control.

Common Applications

Pneumatic solenoid valves are commonly used in:

• Industrial automation
• Pneumatic cylinders
• Manufacturing equipment
• Robotics
• Pneumatic conveying systems
• Fluid power systems
• Gas distribution systems
• Food and beverage processing
• Electronics manufacturing
• Semiconductor equipment
• Special effects equipment
• Animatronics
• OEM machinery
• Air-powered DIY automation projects

These valves are selected wherever compressed air needs to be automatically started, stopped, or redirected.

How Does a Pneumatic Solenoid Valve Work?

A pneumatic solenoid valve uses an electromagnetic coil to shift an internal spool when electrical power is applied.

As the spool moves, compressed air is redirected through different ports, allowing the valve to control actuators, cylinders, and other pneumatic devices.

Because pneumatic valves are directional control valves, they determine where compressed air flows within the system.

Choosing the Right Pneumatic Valve

Selecting the proper pneumatic valve depends on your application.

Choose the Right Valve Configuration

This category includes two common configurations.

3-Way, 2-Position Valves

These valves feature three ports and two operating positions.

They are commonly used when controlling a single actuator or when air needs to be supplied and exhausted through one controlled device.

5-Port (4-Way), 2-Position Valves

These valves feature five ports and two operating positions.

They are commonly used for pneumatic cylinders and applications requiring directional control between two air paths.

Select the Correct Voltage

Choose the coil voltage that matches your power source.

Available options include:

Port Size

Select a valve with a port size that matches your air lines and fittings.

Available port sizes range from:

• 1/8"
• 1/4"
• 3/8"
• 1/2"

All valves feature standard NPT threaded ports for dependable connections.

Valve Construction
