The AirTAC Airtac 4V Solenoid Valves 4V210-06CT is a genuine 5/2-way single solenoid (spring return) solenoid valve with 06CT ports and an effective area of 17.0 mm² (Cv 1.0). It is an internally piloted spool valve that directs compressed air to double-acting cylinders and actuators.
The 4V210-06CT is a single-solenoid, 5/2-way pneumatic directional control valve built on the proven AirTAC 4V200 body. It directs compressed air to one side of a double-acting cylinder or rotary actuator while simultaneously exhausting the opposite side. This model is spring-return, meaning it requires a continuous AC110V electrical signal to hold the actuated position; de-energising the coil immediately returns the spool to its home position via mechanical spring force.
With an effective area of 17.0 mm² (Cv 1.0), this valve comfortably drives double-acting cylinders in the ~O32-50 mm bore range. The 4V210-06CT features 1/8-inch NPT ports and a terminal-box electrical entry. Its AC110V coil draws 4.5 VA, and the sliding-column spool design achieves a response time of 0.05 seconds or less, making it a responsive choice for general industrial automation.

Size the valve so effective area / Cv is not the bottleneck for your cylinder bore and speed. Undersized valves slow the actuator. Note 5/3 (center) versions have a smaller effective area than the 5/2 of the same body size.

Controls a double-acting pneumatic pusher on a conveyor line. The spring-return action ensures the pusher retracts safely when the AC110V signal is cut, clearing the lane for the next product.
Directs air to a clamping cylinder in an automated assembly cell. The Cv 1.0 flow provides fast clamp engagement, while the NPT ports connect easily to North American-standard tooling.
A versatile workhorse for actuating gates, diverters, and simple linear motions on packaging or filling machinery. The AC110V coil integrates directly with common factory control voltage.
Choose the 4V200 body size when your application needs the flow of a Cv 1.0 valve—it sits between the compact 4V100 (Cv 0.6) and the higher-flow 4V300 (Cv 1.65). If you are cycling a small bore cylinder below O25 mm at high speed, stepping down to a 4V100 reduces air consumption. For larger bores above O63 mm or demanding cycle rates, the 4V300 provides the extra conductance. This single-solenoid configuration is ideal when the valve must default to a known safe position on power loss.
When replacing an existing valve, match five points: confirm the body is 4V200, the function is a 5/2 single solenoid, the port size and thread are 1/8-inch NPT, the coil voltage is AC110V, and the electrical entry is a terminal box. For multi-valve assemblies, this unit mounts directly onto a 4V200 manifold base, simplifying plumbing and reducing potential leak points.
Quick checklist
With an effective area of 17.0 mm² (Cv 1.0), it suits double-acting cylinders roughly in the O32-50 mm bore range for typical industrial cycle rates. The exact speed depends on your operating pressure, tubing diameter, and cylinder stroke, but this valve provides a balanced flow for mid-size actuators.
This valve requires a constant AC110V signal to stay in the actuated position. The moment power is removed—whether intentionally or due to an E-stop—the internal spring mechanically pushes the spool back to its default state. This makes it a predictable choice for applications where the actuator must return to a home position for safety or process reasons.
