About the AirTAC 4V210-08 Solenoid Valve, 4V200 Series (4V21008-X0)
The AirTAC 4V21008-X0 is the 4V210-08 valve supplied as a bare body: it ships without the solenoid coil and without the electrical connector, so you fit the coil of your chosen voltage at installation. Mechanically it is the standard 4V200-series 5/2 single-solenoid valve with spring return - energise the coil and pressurised air is directed to one side of a double-acting cylinder while the other side exhausts; cut the signal and the internal spring drives the spool back to its rest position automatically.
With an effective area of 17 mm2 (Cv 1.0), a 1/4in PT (Rc tapered) port at inlet, outlet and a 1/8in exhaust, and a 220 g aluminium body, this valve sits in the workhorse class for bores of roughly O32-50 mm. Valve response is 0.05 s or less, and the spool design, 0.15-0.8 MPa operating range and IP65-rated construction are unchanged from the fully equipped 4V210-08.

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 (4V21008-X0) Is Used
Cylinder actuation
Directs air to double-acting cylinders in the O32-50 mm class for press, lift and position routines, with the spring return bringing the actuator home whenever the electrical signal drops.
Clamping and pushers
Cv 1.0 flow suits clamps, ejectors and pusher units on fixtures and conveyor lines where the part must release to a safe rest state on signal loss.
OEM and maintenance stock
A bare replacement body lets panel builders and maintenance teams hold one pneumatic spare and fit whichever 4V200 coil voltage the machine needs.
Is the AirTAC 4V210-08 Solenoid Valve, 4V200 Series (4V21008-X0) the Right Valve?
Choose this 4V200 body where Cv 1.0 matches the cylinder: drop to the 4V100 (Cv 0.6) for small bores or slow strokes, step up to the 4V300 (Cv 1.65) for larger bores or faster cycling. A single solenoid with spring return suits circuits where the cylinder must return to a known rest position whenever the signal is lost; pick the double-solenoid 4V220 for a memory function or a 4V230C/E/P when a 5/3 center condition is needed. Mount singly or on a manifold base for multi-valve stations.
When replacing, match five points: body size (4V200), function (single 5/2), port and thread (1/4in PT - order -G for BSPP or -T for NPT alternatives), and your required coil voltage and electrical entry, since the -X0 body takes the coil separately.
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 (4V21008-X0) FAQ
No. The -X0 option is the coil-less valve body only: the solenoid coil and the electrical connector are not supplied and must be ordered separately at the voltage your control circuit uses (AC220V, AC110V, AC24V, DC24V or DC12V). The retaining nut is usually kept on the body. Pneumatic performance - 5/2 spring-return function, 1/4in PT ports, 17 mm2 (Cv 1.0) - is identical to the standard 4V210-08.
It is a 5/2 single-solenoid valve for double-acting cylinders and actuators, with an effective area of 17 mm2 and Cv 1.0 - a practical match for bores around O32-50 mm. Because the spool is spring returned, the cylinder goes to its rest position whenever the electrical signal is cut, which makes the valve a good fit for cycles that must default to one end of stroke on power or signal loss.
