About the Airtac 4V200 Solenoid Valve 4V210-08-A
The AirTAC 4V210-08A is a 5/2-way single-solenoid valve that directs compressed air to one side of a double-acting cylinder while exhausting the other. Its spring-return mechanism requires a constant AC220V signal to hold the shifted position; de-energising the coil immediately returns the spool to its home state, making it a predictable choice for applications where the actuator must default to a safe position on power loss.
Built on the 4V200 aluminium-alloy body, this valve delivers an effective area of 17.0 mm2 (Cv 1.0) and suits double-acting cylinders in the ~O32-50 mm bore range. The AC220V coil draws 4.5 VA, and the sliding-column spool responds in 0.05 s or less, giving crisp, repeatable shifts in general-purpose pneumatic circuits.

Flow & Coil Options
| Effective area | 17.0 mm² |
|---|---|
| Flow coefficient | Cv 1.0 |
| Response time | ≤ 0.05 s |
| Coil power | AC 4.5 VA · DC24V 3.0 W · DC12V 2.5 W |
| Protection / insulation | IP65 (DIN40050), B-class |
| Voltage options | DC24V, DC12V, AC110V, AC220V |
| Manual override | Yes (locking / non-locking) |
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.

Where the Airtac 4V200 Solenoid Valve 4V210-08-A Is Used
Conveyor Diverters
Drives a double-acting pusher cylinder that diverts cartons off a belt. The spring-return action ensures the pusher retracts when the AC220V signal is cut, preventing a lane blockage.
Assembly Clamps
Controls a clamping cylinder on a fixture. The 4.5 VA AC coil is easy to wire into existing 220V control panels, and the 0.05 s response helps hit short tact times.
General Machine Actuation
Operates gates, stops, or lift cylinders across packaging and light automation machinery. The IP65-rated terminal box and aluminium body hold up in dusty plant environments.
Is the Airtac 4V200 Solenoid Valve 4V210-08-A the Right Valve?
Choose the 4V210-08A when you need a single-solenoid 5/2 with AC220V control and a spring-driven return that does not rely on air pressure. If your cylinder is smaller than O32 mm, the 4V100 series (Cv 0.6) may offer a better size match; for bores above O50 mm or faster stroke times, step up to the 4V300 (Cv 1.65).
When replacing an existing valve, confirm five points: the 4V200 body size, the 5/2 single-solenoid function, 1/4-inch PT (Rc) ports, an AC220V coil, and the terminal-box electrical entry. This model can be mounted individually or ganged on a manifold base, which simplifies plumbing when several valves share a common supply and exhaust.
Quick checklist
- ✓ Required flow (Cv) for cylinder & speed
- ✓ Function: single / double / 5-3 center
- ✓ Coil voltage (DC24 / AC220 …)
- ✓ Port thread (M5 / 1/8 / 1/4 / 3/8 / 1/2)
- ✓ Single valve or manifold base?
Installation & Wiring Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 0.8 MPa operating pressure.
- check Match coil voltage to your controller output.
- check Use the manual override to test before powering.
- check Fit silencers or fittings to the exhaust ports.
- check Wiring by qualified personnel per AirTAC docs.
Airtac 4V200 Solenoid Valve 4V210-08-A FAQ
With an effective area of 17.0 mm2 (Cv 1.0), it is a strong match for double-acting cylinders in the ~O32 to O50 mm bore range. Smaller cylinders will cycle faster than needed, while larger bores may see slower fill times—consider the 4V300 series for O63 mm and above.
The internal spring forces the spool back to its home position the moment the AC220V coil de-energises. This means the controlled cylinder will return to its default state without any pilot air or electrical hold, which is useful for fail-safe retract or extend setups.
