About the Airtac 4V200 Solenoid Valve 4V220-08-B
The AirTAC 4V220-08B is a 5/2-way double solenoid valve from the popular 4V200 series, configured with a DC24V coil and terminal box entry. It directs compressed air to double-acting cylinders and actuators, and because it is a dual-coil design, the spool stays in its last commanded position when power is removed—no holding current required. This memory function is ideal for applications where the actuator must not shift during an E-stop or power cycle.
With an effective area of 17.0 mm² (Cv 1.0) and a maximum cycling rate of 5 cycles per second, this 320 g valve is sized for driving cylinders in the ~O32-50 mm range. The aluminum alloy body operates from 0.15-0.8 MPa, and the DC24V coil draws just 3.0 W of power. Response time is 0.05 s or less, ensuring crisp, repeatable shifts in high-speed automation sequences.

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 |

Where the Airtac 4V200 Solenoid Valve 4V220-08-B Is Used
Pallet Stop Gates
The memory hold keeps a stop gate raised or lowered during a line stoppage without drifting, then resumes on the next pulse.
Clamp & Hold Fixtures
Pulse the valve to clamp a part, remove power to the coil, and the clamp stays engaged indefinitely while other operations proceed.
Diverters on Packaging Lines
A brief signal toggles a diverter flap between two lanes; the double solenoid holds the last position through power fluctuations.
Is the Airtac 4V200 Solenoid Valve 4V220-08-B the Right Valve?
Choose the 4V220-08B when your circuit needs a 5/2 valve that holds position on power loss without a spring return. If your cylinder is smaller (below ~O32 mm) and speed is less critical, the 4V100 series (Cv 0.6) may be a better match; for larger bores or faster fill rates, step up to the 4V300 (Cv 1.65). The double solenoid configuration is distinct from the single solenoid 4V210—the 4V210 requires a continuous signal to stay shifted, while this model only needs a pulse. For manifold mounting, confirm your base matches the 4V200 body size, and always verify the five-point replacement check: body series (4V200), function (20/double), port size (1/4in), coil voltage (DC24V), and electrical entry (terminal box).
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 4V220-08-B FAQ
The spool is shifted by a momentary electrical pulse to either coil. When the signal stops, balanced pressure and spool land friction hold it in place—no spring, no magnet, no continuous current. It will stay in that position until the opposite coil is pulsed.
With a Cv of 1.0 and 17.0 mm² effective area, it suits double-acting cylinders roughly O32 mm to O50 mm in typical industrial cycles. For very high-speed applications with larger bores, consider the 4V300 series.
