About the AirTAC 4V210-08 Solenoid Valve, 4V200 Series (4V21008A-W)
The 4V21008A-W is the -W variant of the 4V210-08A: a 5/2-way, single-solenoid, spring-return valve for double-acting cylinders and pneumatic actuators. In one coil position the extend side is pressurised while the retract side exhausts; de-energising lets the spring snap the spool home. Choose it wherever the machine must always settle back to a known position after a stop or a restart.
Flow sits at 17.0 mm2 (Cv 1.0), enough for ~O32-50 mm bore cylinders, and the valve tolerates 5 shifts per second with a response of 0.05 s or below. The AC220V coil takes just 4.5 VA through its terminal box on PT1/4 ports; the 220 g aluminium spool body needs no lubrication and only air filtered to 40 um. Shipped as a genuine AirTAC component.

Specifications follow the official AirTAC 4V series datasheet. Lubrication not required. Confirm coil voltage and thread (PT / NPT / G) against the product label before wiring.
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 4V210-08 Solenoid Valve, 4V200 Series (4V21008A-W) Is Used
Tote diverter on sortation conveyors
A ~O32 mm diverter cylinder, fed at Cv 1.0, swings totes between two lanes; the spring return drops the diverter clear whenever the AC220V coil is cut.
Sample-lift in lab automation
Repetitive lift-lower motions suit the 5 cycle-per-second rating and 0.05 s response, with the return stroke guaranteed by the spring rather than by software timing.
Bench-top actuator test rigs
Technicians toggle one coil to cycle a test cylinder through its stroke; the terminal-box AC220V coil at 4.5 VA runs straight from standard workshop supply.
Is the AirTAC 4V210-08 Solenoid Valve, 4V200 Series (4V21008A-W) the Right Valve?
If your bore is small and speed unimportant, the 4V100 body at Cv 0.6 does the same job more cheaply; if strokes are long or the bore grows past ~O50 mm, move to the 4V300 at Cv 1.65. Need the cylinder to stay put when power fails? Pick the double-solenoid 4V220-08 (memory) or the closed-centre 5/3 4V230C-08 (Cv 0.8, 3 cycles per second) - and back any load-holding duty with a check valve or mechanical brake where a dropped load is a risk. Single valves thread straight into the circuit, or several can share one manifold base. When replacing, verify five items: 4V200 body size, function 10, 1/4 in PT porting, AC220V coil, terminal entry.
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 4V210-08 Solenoid Valve, 4V200 Series (4V21008A-W) FAQ
Check five points and it drops in: 4V200 body size, function 10 (single solenoid, spring return), 1/4 in PT inlet and outlet ports (the exhaust on this body is 1/8 in), AC220V coil at 4.5 VA, and terminal-box entry. Flow is Cv 1.0 (17.0 mm2) with an operating band of 0.15-0.8 MPa and a 1.2 MPa proof pressure.
No lubrication is required, but the air must pass a 40 um filter element and pressure must stay within 0.15-0.8 MPa. The valve works from -20 to +70 C, insulation is class B, and the manual override can be specified as locking or non-locking.
