About the AirTAC 4V220-08AI Solenoid Valve, 5/2-way, PT1/4, AC220V, grommet entry (4V22008AI)
The AirTAC 4V220-08AI is a 5/2-way double-solenoid directional control valve built on the proven 4V200 aluminum body. It directs compressed air to double-acting cylinders and actuators, and because it is a double-solenoid design, the spool holds its last pulsed position when power is removed—no constant signal is needed. This memory function is ideal for circuits where the actuator must stay put during an E-stop or power cycle without an external pilot holding circuit.
This specific configuration arrives pre-wired with a 0.5 m flying lead via a DIN-style grommet (I-type entry) and an AC220V coil drawing 4.5 VA. With 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. The IP65-rated enclosure and locking manual override make it a robust, field-ready solution for general industrial automation.

Where the AirTAC 4V220-08AI Solenoid Valve, 5/2-way, PT1/4, AC220V, grommet entry (4V22008AI) Is Used
Holding Position on Power Loss
In automated conveyor diverters or gates, the double-solenoid memory holds the diverter in its last commanded position if the machine E-stops, preventing product jams or mis-sorts until power is restored.
Clamp & Fixture Control
Operates double-acting clamps on assembly fixtures. The memory function keeps the clamp engaged during a power cycle, so parts remain securely fixtured without needing a constant hold signal.
Packaging & Palletising
Controls pushers and lift cylinders on case packers. The AC220V grommet entry simplifies wiring into the machine's main AC supply, while the 4V200's 5 c/s max frequency handles moderate-speed palletising cycles.
Is the AirTAC 4V220-08AI Solenoid Valve, 5/2-way, PT1/4, AC220V, grommet entry (4V22008AI) the Right Valve?
Step up to this 4V200-body valve when your cylinder bore or speed requirement outpaces the smaller 4V100 series (Cv 0.6). If you need even higher flow for large actuators or very fast cycle times, the 4V300 body (Cv 1.65) is the next tier. Choose this double-solenoid (20) version when the application demands that the cylinder holds its last position after a power loss—the spool stays put by land friction and balanced pressure, not a magnetic latch. For a valve that must spring-return to a safe home position on power loss, select the single-solenoid 4V210 instead.
When replacing an existing valve, match these five points: body size (4V200), function (double 5/2), port and thread (1/4in PT), coil voltage (AC220V), and electrical entry (grommet with flying lead). This model can be used as a single valve or mounted on a manifold base to build a compact, integrated valve group.
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 4V220-08AI Solenoid Valve, 5/2-way, PT1/4, AC220V, grommet entry (4V22008AI) FAQ
With an effective area of 17.0 mm² (Cv 1.0), this 4V200-body valve suits double-acting cylinders approximately O32 to O50 mm in bore. For smaller O20-25 mm cylinders, a 4V100 series valve (Cv 0.6) may provide more precise control; for larger O63-100 mm bores or very high-speed applications, consider stepping up to the 4V300 series (Cv 1.65).
The spool is shifted by a momentary pulse to either solenoid and remains in that position by land friction and balanced pressure—no spring, holding current, or magnetic latching is involved. While this holds the actuator position during a power loss, it is not a certified safety brake. For suspended or vertical loads where unintended drift poses a hazard, always add a dedicated mechanical brake or pilot-operated check valve at the cylinder ports.
