About the AirTAC 4V220-06BI Solenoid Valve, 5/2-way, PT1/8, DC24V, grommet entry (4V22006BI)
The 4V220-06BI is a 5/2-way double-solenoid valve from the AirTAC 4V200 series, configured with a DC24V coil and a pre-wired grommet entry for fast DIN-style connection. It directs compressed air to both sides of a double-acting cylinder, and its memory function means the spool stays in the last pulsed position even if power is interrupted—no holding current is needed.
This 1/8-inch PT-ported model delivers a Cv of 1.0 (effective area 17.0 mm²) and weighs 320 g, suiting it for central control of ~Ø32-50 mm cylinders. The response time is 0.05 seconds or less, and the IP65-rated enclosure with a 0.5 m flying lead simplifies wiring into tight machine cabinets.

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 4V220-06BI Solenoid Valve, 5/2-way, PT1/8, DC24V, grommet entry (4V22006BI) Is Used
Indexing Conveyor Stops
The memory hold keeps a stop gate raised or lowered through a power cycle, preventing a reset sequence on restart and protecting product flow timing.
Clamp & Hold Fixtures
Pulse the valve to clamp a part, then remove power. The spool stays put, maintaining clamping force on the double-acting cylinder without coil heating.
Central Manifold Logic
The grommet lead and 1/8-inch port make it easy to gang multiple 4V220-06BI valves on a base, building a memory-based sequence controller for an assembly cell.
Is the AirTAC 4V220-06BI Solenoid Valve, 5/2-way, PT1/8, DC24V, grommet entry (4V22006BI) the Right Valve?
Choose this 4V220-06BI when you need a 5/2 valve that remembers its last state during an E-stop or cycle interruption, eliminating the need for a constant electrical signal. The 1/8-inch port matches compact cylinder plumbing, while the grommet entry avoids a bulky terminal box in space-constrained manifolds.
For smaller Ø20-32 mm cylinders, a 4V100 series (Cv 0.6) may offer finer control; for larger bores or faster stroking, step up to a 4V300 (Cv 1.65). When replacing, match all five points: 4V200 body, double-solenoid function (20), 1/8-inch PT port, DC24V coil, and grommet electrical 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 4V220-06BI Solenoid Valve, 5/2-way, PT1/8, DC24V, grommet entry (4V22006BI) FAQ
With a Cv of 1.0 and 17.0 mm² effective area, it suits double-acting cylinders in the ~Ø32-50 mm range for general industrial speeds. For very high-speed applications on a 50 mm bore, verify the cycle rate against the valve's 5 cycles/second maximum frequency.
No. The 4V220-06BI is a dual-coil spool valve. The spool remains in its last shifted position through balanced pressure and land friction, not a magnet. It does not consume power to hold position, but it is not a safety-rated holding device for suspended loads.
