About the AirTAC 4V220-08E Solenoid Valve, 5/2-way, PT1/4, AC24V, terminal entry (4V22008E)
The AirTAC 4V220-08E is a 5/2-way double-solenoid pneumatic directional valve built on the proven 4V200 aluminium body. It directs compressed air to both sides of a double-acting cylinder or rotary actuator, and its memory-type spool stays in the last pulsed position even when the AC24V coil is de-energised—no holding current is needed. The spool is retained by land friction and balanced pressure, not by a magnet, so it is ideal for applications where you want a cylinder to hold its end-of-stroke state through a power cycle.
This model carries an AC24V (50/60 Hz) coil drawing 5.0 VA, wired through the standard terminal box entry. With a 1/4-inch PT inlet and outlet and a 1/8-inch PT exhaust, it delivers an effective area of 17.0 mm² (Cv 1.0) and cycles at up to 5 times per second. Response time is 0.05 seconds or less, and the IP65-rated enclosure keeps the sliding-column spool clean in dusty or washdown environments.

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 4V220-08E Solenoid Valve, 5/2-way, PT1/4, AC24V, terminal entry (4V22008E) Is Used
Pallet Stop & Gate Control
The memory spool holds a stop gate open or closed without constant power, reducing coil heat in indexing conveyor systems. The AC24V supply is common in material-handling panels.
Clamp & Fixture Stations
A pulsed signal sets the clamp; it stays locked even if the machine control power cycles. The 17.0 mm² effective area provides ample force for mid-bore clamping cylinders.
Packaging Machine Diverters
Use the 4V220-08E to hold a diverter gate in its last commanded position through a production stop. The 5 c/s max frequency handles rapid sortation on small carton lines.
Is the AirTAC 4V220-08E Solenoid Valve, 5/2-way, PT1/4, AC24V, terminal entry (4V22008E) the Right Valve?
Choose the 4V220-08E when your double-acting cylinder (roughly 32 to 50 mm bore) needs to lock its last position on power loss without a constant electrical signal. If your cylinder is smaller (below 32 mm) and you want to save space, step down to the 4V100 series (Cv 0.6); if you need faster fill on a 63 mm or larger bore, move up to the 4V300 (Cv 1.65). The double-solenoid memory function is the key differentiator from the spring-return 4V210—use it when a machine must not automatically retract on an E-stop.
For a drop-in replacement, match all five elements: the 4V200 body size, the 5/2 double-solenoid function (20), the 1/4-inch PT port, the AC24V coil voltage, and the terminal-box electrical entry. If you are building a multi-valve station, this model mounts directly onto a 4V200 manifold base, letting you gang up to 20 valves with a common supply and exhaust.
Quick checklist

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 4V220-08E Solenoid Valve, 5/2-way, PT1/4, AC24V, terminal entry (4V22008E) FAQ
The 4V220-08E is a double-solenoid valve with a memory spool. The spool stays in the position it was last pulsed to, held by friction and balanced air pressure, so the cylinder remains at its end-of-stroke position. It does not use a spring or a magnetic latch. For suspended-load safety, you must add an external pilot-operated check valve or mechanical brake.
No, the 'E' suffix denotes an AC24V (50/60 Hz) coil rated at 5.0 VA. For DC24V, order the 4V220-08B; for AC220V, order the 4V220-08A. The coil is field-replaceable, but you must match the voltage to your control system to avoid burnout.
