The AirTAC AirTAC 4V210-06E Solenoid Valve, 5/2-way, PT1/8, AC24V, terminal entry (4V21006E) is a genuine 5/2-way single solenoid (spring return) solenoid valve with 21006E 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 AirTAC 4V210-06E is a single-solenoid, spring-return 5/2-way pneumatic directional valve in the popular 4V200 body size. It directs compressed air to one side of a double-acting cylinder or rotary actuator while exhausting the opposite side, then automatically returns the spool to its home position via mechanical spring force the moment the AC24V electrical signal is removed.
Configured with a 1/8-inch PT port and a 5.0 VA AC24V coil inside a standard terminal box, this model suits continuous-duty applications where a constant signal is acceptable. The sliding-spool mechanism delivers a 17.0 mm2 effective area (Cv 1.0) and an actuation response of 0.05 seconds or less, making it a precise pilot for cylinders in the O32 to O50 mm range.

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.

Energise the AC24V coil to extend a clamp cylinder; de-energise to retract. The spring-return design guarantees the clamp opens if power is interrupted, protecting the workpiece and tooling.
Use the 4V210-06E to shift a pneumatic diverter on a packaging conveyor. The 0.05 s response keeps pace with moderate-speed sortation, while the 1/8-inch port simplifies tubing runs.
A workhorse valve for single-station automation. Pair it with a O40 mm double-acting cylinder on a press or pusher; the 17.0 mm2 effective area provides ample flow for smooth, consistent stroking.
Choose the 4V210-06E when your system runs on AC24V control power and you need a reliable spring-return action that defaults to a known position on power loss. Its 1/8-inch port and Cv 1.0 flow capacity are well-matched to mid-sized double-acting cylinders; for smaller O20 mm cylinders, stepping down to the 4V100 series (Cv 0.6) often yields a more compact and economical installation.
When replacing an existing valve, match five points: confirm the 4V200 body size, the 5/2 single-solenoid function, the 1/8-inch PT thread, the AC24V coil voltage, and the terminal-box electrical entry. If you later need to group multiple valves, this unit mounts directly onto a 4V200 manifold base without adapters.
Quick checklist
With an effective area of 17.0 mm2 (Cv 1.0), this 5/2 valve suits double-acting cylinders approximately O32 to O50 mm in bore. For significantly smaller cylinders (O20 mm or less), a 4V100-series valve with Cv 0.6 often provides better speed control.
The internal spring mechanically forces the spool back to its default position the instant the coil de-energises. This means the cylinder will retract (or extend, depending on port plumbing) automatically, making the valve predictable for applications where a fail-safe rest position is needed.
