AirTAC 4V210-08 Solenoid Valve, 4V200 Series (4V21008B-AM-W)
The AirTAC AirTAC 4V210-08 Solenoid Valve, 4V200 Series (4V21008B-AM-W) is a genuine 5/2-way single solenoid (spring return) solenoid valve with W 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.

About the AirTAC 4V210-08 Solenoid Valve, 4V200 Series (4V21008B-AM-W)
Ordering the 4V21008B-AM-W gives you the proven 4V200 single-solenoid 5/2 body in its 1/4in PT, DC24V, terminal-box configuration, with the -W ordering suffix carried in the model code. One coil shifts the spool; a return spring resets it when the signal is removed, so any double-acting cylinder it drives always parks in the home position - the classic fail-to-home logic for clamps, pushers and diverters.
At 220 g the valve is light enough for bracket-mounting directly on the machine, and it keeps switching at up to 5 cycles per second without derating. The 3.0 W DC24V coil runs cool through continuous duty, IP65 (DIN40050) sealing protects the terminals, and the pilot section can be fed internally or externally depending on how you plumb the base.

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 (4V21008B-AM-W) Is Used
Case ejector on a palletiser
Throw cases onto a takeaway conveyor with an O50 push cylinder (about 982 N at 0.5 MPa); the spring return parks the pusher clear of the case path between cycles.
Sorting-gate diverter
Switch a light diverter flap between two lanes at up to 5 cycles per second - the Cv 1.0 flow class keeps small-bore flap cylinders quick without oversizing the valve.
Bench test-rig actuator
Stroke a double-acting ram on a repeat-load test bench; the terminal box takes fixed 24 V wiring and the 3.0 W coil stays cool through long duty blocks.
Is the AirTAC 4V210-08 Solenoid Valve, 4V200 Series (4V21008B-AM-W) the Right Valve?
Compare against its neighbours before ordering: the 4V100 delivers Cv 0.6 for small O32-class bores, while the 4V300 at Cv 1.65 suits larger cylinders or high-speed strokes beyond what this body's 17.0 mm2 flow class covers. If your logic needs the cylinder to stay put on power loss, swap to the double-solenoid 4V220 (memory) rather than relying on a spring-return valve. The -W suffix rides on top of the core spec, so when replacing a valve copy all five code positions - 4V200 body, function 10, 08 port, B voltage, terminal entry - and verify the suffix against the AirTAC ordering key. For dense layouts, group several 4V200 bodies on one manifold base and share a single air and 24 V supply.
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 (4V21008B-AM-W) FAQ
5/2 flow: 17.0 mm2 effective area, Cv 1.0, maximum 5 cycles per second. Activation time 0.05 s or less. Operating pressure 0.15-0.8 MPa with 1.2 MPa proof pressure, on air filtered by a 40 um element. DC24V coil at 3.0 W, IP65 protection, insulation class B, lubrication not required, weight 220 g.
The valve itself is the same 4V200 single-solenoid 5/2 platform, so cross-checking is straightforward: match body size (4V200), function (10, spring return), port and thread (1/4in PT), coil voltage (DC24V) and entry (terminal box), then confirm the -W suffix against the AirTAC ordering key. Like any 4V200 body, it mounts on a shared manifold base with the rest of the range.
