About the AirTAC 4V220-08CI Solenoid Valve, 5/2-way, PT1/4, AC110V, grommet entry (4V22008CI)
This AirTAC 4V220-08CI is a 5/2-way double-solenoid valve that directs compressed air to double-acting cylinders and actuators, using a memory-spool design. When you pulse the AC110V coil, the spool shifts and stays locked in that last-commanded position even if power is completely removed—held by balanced pressure and friction, not by a holding current. This makes it ideal for applications where you want a cylinder to maintain its end-of-stroke state without continuously energizing a coil.
Pre-wired with a 0.5 m flying lead through a DIN-style grommet, the 4V220-08CI simplifies installation in tight cabinets. The valve body delivers a 17.0 mm² effective area (Cv 1.0) and cycles up to 5 times per second, suiting ~O32-50 mm bore cylinders. At 320 g, it is a compact mid-body solution with a sub-0.05-second response time and IP65 protection.

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 4V220-08CI Solenoid Valve, 5/2-way, PT1/4, AC110V, grommet entry (4V22008CI) Is Used
Holding a Gate or Diverter
On a packaging conveyor, a 4V220-08CI shifts a diverter gate to the correct lane and holds it there after a short pulse, even through a control-panel power cycle. The memory function prevents the gate from springing back and misdirecting product.
Clamp-and-Hold Fixtures
In an automated assembly cell, the valve pulses a double-acting clamp closed. The spool remains in the clamped position with zero holding current, keeping the part secure while the machine performs a drilling or fastening operation.
Energy-Conscious Press Actuation
A small pneumatic press uses the 4V220-08CI to extend the tool, then the coil is de-energized. The valve’s memory holds the ram in contact, reducing coil heat buildup and saving energy during long pressing cycles.
Is the AirTAC 4V220-08CI Solenoid Valve, 5/2-way, PT1/4, AC110V, grommet entry (4V22008CI) the Right Valve?
Step up to this 4V220-08CI when you need a 5/2 valve that remembers its position without constant power—unlike the single-solenoid 4V210 which springs back on de-energization. The 4V200 body’s Cv 1.0 flow capacity is sized for mid-range double-acting cylinders; if you are driving a very small O10-20 mm bore, the 4V100 series (Cv 0.6) may be a better fit, while large O63-100 mm cylinders or high-speed cycles call for the 4V300 (Cv 1.65).
For a direct replacement, match these five points: 4V200 body size, 5/2 double-solenoid function (20), 1/4-inch PT port, AC110V coil voltage, and grommet-style electrical entry. The pre-wired grommet lead eliminates the need for a separate terminal-box connector, speeding up panel wiring.
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 4V220-08CI Solenoid Valve, 5/2-way, PT1/4, AC110V, grommet entry (4V22008CI) FAQ
Because this is a double-solenoid memory valve, the spool stays in the position it was last pulsed to. The cylinder will hold its current state—extended or retracted—until the opposite coil receives a signal. It does not require a holding current and is not magnetically latched; the spool is held by friction and balanced pressure.
Yes, functionally it is identical to a terminal-box 4V220-08C, but the electrical entry is different. This CI model comes with a 0.5 m pre-wired flying lead exiting through a DIN grommet, which is convenient for direct connection to a cable duct or when you want to avoid a separate DIN connector. Ensure your machine’s wiring layout can accept a flying-lead entry.
