5/2 Solenoid Valve Working Principle – Interactive Animation

Explore how a 5/2 solenoid valve controls a double-acting pneumatic cylinder. Use this interactive animation to switch between Retract and Extend positions and observe how compressed air flows through the valve.

How Does a 5/2 Solenoid Valve Work?

A 5/2 directional control valve has five ports and two switching positions. It is commonly used in industrial automation to control pneumatic cylinders.

• P – Pressure supply: Receives compressed air.
• A and B – Working ports: Connect to either side of the cylinder.
• R and S – Exhaust ports: Release air from the cylinder.

Two Operating Positions

• Retract: Air flows from P to A, while B connects to exhaust.
• Extend: Air flows from P to B, while A connects to exhaust.

In a single-solenoid, spring-return valve, energizing the solenoid switches the valve to the actuated position. When power is removed, the spring returns it to its normal position.

Applications of 5/2 Solenoid Valves

These valves are widely used in pneumatic actuators, packaging machines, industrial automation systems, and manufacturing equipment.
