What is AirTAC 4V210? Should You Use It?

In pneumatic and automation systems, selecting the right solenoid valve is critical to ensure stable operation, achieve desired speed, and extend equipment life. The AirTAC 4V210 is one of the popular models in the 4V200 series, designed for double-acting cylinders and providing reliable airflow and pressure control. This article explains the technical specifications, applications, advantages, and when it is appropriate to use the 4V210 valve.

1. Introduction to AirTAC 4V210

The AirTAC 4V210 is a 5/2-way or 5/3-way solenoid valve, part of the 4V200 series. It is used to control double-acting cylinders, supplying air alternately to both ends of the cylinder to extend or retract the piston with precise motion. This valve is ideal for medium-sized pneumatic automation systems where fast response and accurate control are required.

According to the 4V200 catalog (pages 1–2), the 4V210 comes in multiple models with different port sizes (1/8” and 1/4”) and Cv flow coefficients, suitable for various pressure ranges

3. Features and Benefits

1. Pilot-oriented mode: Supports internal or external pilot.
2. Robust body: Tight sealing and fast response to airflow.
3. Three solenoid options: Single, double, and memory function available for different control requirements.
4. Can be integrated on a manifold to save space.
5. Equipped with manual override, allowing easy operation and testing.

4. When to Use AirTAC 4V210

1. For systems using double-acting cylinders requiring extension and retraction.
2. When you need a 5/2-way basic valve or a 5/3-way valve with a middle position to temporarily stop the piston.
3. Suitable for medium automation systems where accurate and fast response is essential.
4. Ideal for applications with moderate airflow and pressure requirements, where larger models like 7SV are not necessary.

5. Comparison with Other Series

1. Compared to 4V100 series: 4V210 offers higher Cv and airflow, suitable for medium cylinders.
2. Compared to 7SV series: 7SV is designed for high pressure and large airflow, while 4V210 is adequate for medium-sized systems with lower cost.
3. Selecting the correct model saves energy, protects the coil and piston, and ensures stable system operation.
