About the Airtac 4V200 Solenoid Valve 4V21008F
The AirTAC 4V210-08F is a single-solenoid, 5/2-way pneumatic directional valve that directs compressed air to one side of a double-acting cylinder while exhausting the other. Its spring-return mechanism requires a constant DC12V signal to hold the shifted position; de-energising the 2.5 W coil instantly returns the spool to its home state, making it a predictable choice for basic extend-retract sequences.
Built on the popular 4V200 aluminium body with 1/4-inch PT ports and a terminal-box electrical entry, this valve delivers an effective area of 17.0 mm² (Cv 1.0) and a response time of 0.05 s or less. It suits ~O32-50 mm bore cylinders in general industrial automation where a compact, IP65-rated valve with manual override is needed.

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 4V21008F Is Used
Packaging Pushers
Actuates a pneumatic pusher on a 12 VDC-controlled packaging line. The spring return guarantees the pusher retracts if power is interrupted, protecting product and tooling.
Assembly Clamps
Controls a double-acting clamp on a mobile assembly fixture powered by a 12 V battery. The low 2.5 W draw helps conserve energy, and the IP65 body handles dusty workshop air.
Small Press Feeders
Directs a ~O40 mm feed cylinder on a stamping press. The sub-0.05 s response and Cv 1.0 flow capacity deliver the crisp, repeatable motion that short-stroke feeders demand.
Is the Airtac 4V200 Solenoid Valve 4V21008F the Right Valve?
Choose the 4V210-08F when your application runs on a DC12V power supply and needs a single-coil 5/2 valve that defaults to a known position at power-off. If you are driving a smaller cylinder (below ~O32 mm), the 4V100 series (Cv 0.6) may offer a more economical fit; for larger bores or faster cycle rates, step up to the 4V300 body (Cv 1.65).
For a drop-in replacement, match five points: the 4V200 body size, the 5/2 single-solenoid function (10), the 1/4-inch port with PT thread, a DC12V coil, and the terminal-box wiring style. If you need the spool to hold its last position when power is cut, consider the double-solenoid 4V220 variant instead.
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 4V21008F FAQ
With its 17.0 mm² effective area (Cv 1.0), this 4V200-series valve is a good match for double-acting cylinders in the ~O32-50 mm bore range. Actual speed depends on your supply pressure, tubing diameter and stroke length.
Yes. The 4V210 is a single-solenoid, spring-return valve. The 2.5 W DC12V coil must remain energised the entire time you want the valve in its actuated position. Removing power lets the internal spring push the spool back to the home port connection.
