Electro-pneumatic 5/3 valves

Electro-pneumatic 5/3 valves

Electro-pneumatic 5/3 valves form the core of modern automation. Thanks to the three central positions and five ports, these valves are widely applicable in various industrial processes. This makes them suitable for applications such as precise cylinder control, production lines with adjustable positions, and installations requiring fail-safe operation.

We supply valves from top manufacturers, including technical support for engineering, selection, and installation.

What is an electro-pneumatic 5/3 valve?

A 5/3 valve is a pneumatic spool valve with:

• 5 ports (two outputs, two inputs/air supply, and one exhaust)

• 3 positions (closed, exhaust, or flow)

When electrically actuated, the valve switches between different positions for flexible control of linear and rotary actuators.

Central positions explained:

• Closed center: both cylinder ports are blocked, keeping the cylinder in position

• Exhaust center: the cylinder ports are vented, allowing free movement

• Pressure center: both sides of the cylinder remain pressurized, ready for immediate action and fast response

Advantages of electro-pneumatic 5/3 valves

• High switching speed and precision

• Durable, industrial construction

• Flexible configurations

• Energy-efficient design

• Integration with modern control systems

Applications of 5/3 valves
