About the AirTAC 4V210-08 Solenoid Valve, 4V200 Series (4V21008B-X1)
The AirTAC 4V210-08B-X1 is a 5/2 single-solenoid directional valve with spring return. Energise the coil and pressurised air flows to one side of a double-acting cylinder while the other side exhausts; cut the signal and an internal spring snaps the spool back, reversing the stroke. Because the valve needs a constant electrical signal to stay shifted, it self-cancels the moment your PLC output or E-stop drops out.
Built on the 4V200 body, it moves a 17.0 mm2 effective section (Cv 1.0) through PT1/4 ports and suits double-acting cylinders in the ~O32-50 mm range. The B-code coil runs on DC24V at just 3.0 W, cool enough to drive straight from a transistor PLC card, and spool response is 0.05 s or less. The valve weighs 220 g and carries an IP65 terminal box; the -X1 suffix marks an option variant of the standard 4V210-08B, so the core data here is the base valve's.

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-X1) Is Used
Carton push-off on packaging lines
A 1/4" Cv 1.0 port flow keeps an O40 double-acting pusher cycling cartons briskly on short strokes, and the spring return retracts the pusher the instant the line stops.
Pneumatic clamp on welding fixtures
Energise to clamp, cut the PLC signal and the spring vents the clamp home, so a jammed workpiece cannot keep the fixture locked after an abort.
Pick-and-place mini gantry
The DC24V coil draws only 3.0 W and switches directly from a robot controller output; response of 0.05 s or less keeps O32-50 mm actuator dwell predictable.
Is the AirTAC 4V210-08 Solenoid Valve, 4V200 Series (4V21008B-X1) the Right Valve?
Step down to the 4V100 (Cv 0.6) when the cylinder is under ~O32 mm and speed is not critical; step up to the 4V300 (Cv 1.65) when you need a faster cycle on a bore beyond ~O50 mm. This 5/2 spring-return single solenoid is the right pick when the actuator must go home on signal loss; choose the double-solenoid 4V220 for a memory function, or a 4V230C/E/P 5/3 if the mid-position must block, exhaust or pressurise. A single valve mounts directly, or seat it on a manifold base to share one supply across a group. To replace a unit, match five points: 4V200 body, function digit (10 here), 1/4" port with PT thread, DC24V coil, and terminal-box 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 (4V21008B-X1) FAQ
It is a 5/2 spring-return valve with a 17.0 mm2 effective section and Cv 1.0, meant for double-acting cylinders and rotary actuators in the ~O32-50 mm class. Single-acting cylinders need a 3/2 valve instead. Maximum cycling is 5 strokes per second.
Flow: 17.0 mm2 effective area, Cv 1.0. Response: 0.05 s or below. Pressure: 0.15-0.8 MPa working, 1.2 MPa proof. Electrical: DC24V coil at 3.0 W, terminal-box entry, IP65, class B insulation. Media air must be filtered to 40 um; lubrication is not required.
