High-Efficiency Automation: Implementing Dual Pressure Circuits with Airtac 4V210-08

April 30, 2026

In modern industrial design, applying maximum pressure at all times is often inefficient and unnecessary. The Airtac 4V210-08 solenoid valve, with its versatile 5/2-way configuration, serves as an ideal component for dual-pressure logic circuits. This setup allows you to apply high force only when needed, significantly reducing air consumption and mechanical wear.

1. The Dual-Pressure Logic: High Force vs. Soft Touch

Standard pneumatic circuits use a single pressure for both strokes. However, many applications—such as pressing, stamping, or clamping—only require high force during the "Extend" phase.

The Configuration: By integrating two separate Airtac AR Series regulators upstream of the valve, you can feed a high-pressure line (e.g., 0.7 MPa) for the work stroke and a low-pressure line (e.g., 0.2 MPa) for the return stroke.
The Airtac 4V210-08 Advantage: Thanks to its high-precision spool design and 1/4" NPT/PT ports, the 4V210-08 handles these pressure transitions with zero lag, ensuring your cycle time remains optimized even with varying air densities.

2. Protecting Delicate Tooling and Workpieces

A major benefit of the dual-pressure approach is the "Soft Retract."

Preventing Damage: For assembly lines involving fragile electronic components or glassware, using low pressure for the retraction stroke prevents the cylinder from slamming into its home position.
Energy Savings: Since air consumption is proportional to pressure, cutting the return stroke pressure by 60% can lead to substantial annual energy savings in high-duty cycle environments.

3. Implementation Tip: Check Valve Integration

When designing dual-pressure circuits with the 4V210-08, ensure you use Airtac KA Series check valves to prevent backflow between the high and low-pressure lines. This ensures a stable 24V DC signal response and consistent cylinder speed.
