About the AirTAC 4V220-08BI Solenoid Valve, 5/2-way, PT1/4, DC24V, grommet entry (4V22008BI)
The AirTAC 4V220-08BI is a 5/2-way double-solenoid directional valve that directs compressed air to double-acting cylinders and rotary actuators. Its memory function means the spool stays in its last pulsed position when power is removed—no spring to shift it, no holding current required—making it ideal for sequences where the actuator must hold a state during a power-off or E-stop event.
This configuration ships with a DC24V coil (3.0 W power draw) and a grommet-style electrical entry with a 0.5 m pre-wired flying lead, speeding up DIN-rail panel builds. The 4V200 body delivers an effective area of 17.0 mm² (Cv 1.0) and a response time ≤ 0.05 s, comfortably cycling ~O32-50 mm double-acting cylinders at up to 5 cycles per second.

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 |

Where the AirTAC 4V220-08BI Solenoid Valve, 5/2-way, PT1/4, DC24V, grommet entry (4V22008BI) Is Used
Material Diverting Gates
Pulse the 4V220-08BI to swing a diverter gate; the memory hold keeps the gate in position through power dips, preventing jams on packaging conveyors.
Assembly Clamping Fixtures
Energize to clamp, de-energize and the valve holds pressure. The 3.0 W DC24V coil runs cool in dense fixture manifolds, and the grommet lead simplifies wiring.
Pneumatic Pusher Stations
Drive a double-acting pusher cylinder with a start pulse; the spool holds extend until a retract pulse arrives. The 17.0 mm² effective area gives crisp actuation for O40 mm cylinders.
Is the AirTAC 4V220-08BI Solenoid Valve, 5/2-way, PT1/4, DC24V, grommet entry (4V22008BI) the Right Valve?
Choose the 4V220-08BI when your application needs a 5/2 valve that remembers its position without constant power—common in clamping or diverting stations where holding state during a machine pause prevents product loss. The 1/4 in PT ports and DC24V grommet wiring suit compact manifold or stand-alone installations.
For smaller cylinders (O20-25 mm) where the Cv 1.0 is oversized, step down to a 4V100-series valve (Cv 0.6). If you are driving a larger bore (O63 mm+) or need faster fill rates, move up to the 4V300 (Cv 1.65). When replacing an existing valve, match five points: 4V200 body, 5/2 double-solenoid function, 1/4 in PT port, DC24V coil, and grommet electrical entry.
Quick checklist
- ✓ Required flow (Cv) for cylinder & speed
- ✓ Function: single / double / 5-3 center

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 4V220-08BI Solenoid Valve, 5/2-way, PT1/4, DC24V, grommet entry (4V22008BI) FAQ
With an effective area of 17.0 mm² (Cv 1.0), it suits double-acting cylinders in the ~O32-50 mm range for typical 0.5-0.7 MPa supply pressures. It cycles at up to 5 times per second, so it handles moderate-speed general automation tasks well.
Yes, the double-solenoid memory design means the spool stays in its last pulsed position without any holding current. It is not a magnetic latch—the spool is held by friction and balanced pressure. For a suspended load, always add a pilot-operated check valve or mechanical brake.
