About the AirTAC 4V220-08EI Solenoid Valve, 5/2-way, PT1/4, AC24V, grommet entry (4V22008EI)
The 4V220-08EI is a 5/2-way double-solenoid valve that directs compressed air to double-acting cylinders and actuators with a memory-hold function. When you pulse the coil, the spool shifts and stays in that last commanded position even if power is completely removed—held by land friction and balanced pressure, with no spring to move it and no holding current required.
This model comes pre-wired with a 0.5 m flying lead through a DIN-style grommet entry and operates on an AC24V coil drawing 5.0 VA. Built on the 4V200 aluminum-alloy body, it delivers an effective area of 17.0 mm² (Cv 1.0) and suits cylinders in the ~Ø32-50 mm range. Response time is 0.05 s or below, and the IP65-rated enclosure handles washdown environments with confidence.

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 4V220-08EI Solenoid Valve, 5/2-way, PT1/4, AC24V, grommet entry (4V22008EI) Is Used
Packaging Line Diverters
The memory-hold function keeps a diverter gate in its last pulsed position during a line stop, so product flow resumes correctly without a re-homing sequence.
Clamp & Fixture Control
Pulse the coil to clamp a part and the 4V220-08EI holds pressure on the cylinder even when the machine controller powers down, preventing workpiece release.
Pneumatic Gate Actuation
Drives double-acting cylinders on safety gates or access panels. The AC24V grommet wiring simplifies installation where low-voltage control circuits are preferred.
Is the AirTAC 4V220-08EI Solenoid Valve, 5/2-way, PT1/4, AC24V, grommet entry (4V22008EI) the Right Valve?
Choose the 4V220-08EI when your application needs a valve that remembers its position through an E-stop or power cycle without a spring return. For smaller cylinders around Ø20-25 mm, stepping down to the 4V100 series (Cv 0.6) saves space and air; for larger bores above Ø63 mm or faster cycle rates, the 4V300 (Cv 1.65) provides the extra flow capacity you need.
When replacing an existing valve, match all five points: body size (4V200), function (double-solenoid 5/2), port size and thread (1/4" PT), coil voltage (AC24V), and electrical entry (grommet with flying lead). If you are building a multi-valve station, this body mounts directly onto a 4V200 manifold base for a clean, integrated assembly.
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 4V220-08EI Solenoid Valve, 5/2-way, PT1/4, AC24V, grommet entry (4V22008EI) FAQ
With an effective area of 17.0 mm² (Cv 1.0), it is well-matched to double-acting cylinders in the ~Ø32-50 mm range. It provides crisp, full-stroke actuation at up to 5 cycles per second for general industrial tasks.
No—the spool holds its position on loss of electrical power, but if supply air pressure drops, the cylinder can drift. The hold is purely mechanical (spool friction and pressure balance), not magnetic latching. For suspended-load safety, add a pilot-operated check valve at the cylinder ports.
