About the AirTAC 4V220-08C Solenoid Valve, 5/2-way, PT1/4, AC110V, terminal entry (4V22008C)
The AirTAC 4V220-08C is a 5/2-way double-solenoid directional control valve built on the 4V200 body, directing compressed air to double-acting cylinders and actuators. Because it is a two-coil memory valve, it holds its last spool position when power is removed—no spring return and no holding current required—making it ideal for sequences where the cylinder must stay put during an E-stop or power cycle.
This AC110V terminal-box version weighs 320 g and switches in 0.05 s or less. With an effective area of 17.0 mm² (Cv 1.0) and a 5 cycles/sec max frequency, it suits ~O32-50 mm bore cylinders in general automation. The IP65 enclosure and B-class insulation keep it reliable in washdown-light factory environments.

Where the AirTAC 4V220-08C Solenoid Valve, 5/2-way, PT1/4, AC110V, terminal entry (4V22008C) Is Used
Diverters & Sortation Gates
The 4V220-08C’s memory hold keeps a diverter gate in its last commanded position during a line stop or power cycle, preventing product mis-routing when the system restarts.
Clamping & Fixturing Stations
Double-acting clamps stay locked or released without holding current, reducing coil heat and energy consumption on long-cycle assembly fixtures.
Pick-and-Place End-Effectors
Controls a gripper or vacuum cup slide with a 5 c/s cycle rate; the 1/4" port and Cv 1.0 flow provide crisp actuation for O32-50 mm bore cylinders on end-of-arm tooling.
Is the AirTAC 4V220-08C Solenoid Valve, 5/2-way, PT1/4, AC110V, terminal entry (4V22008C) the Right Valve?
Step up to the 4V220-08C when your application needs a 5/2 valve that remembers its state without a continuous electrical signal. The double-solenoid memory action eliminates the constant coil consumption of a spring-return model and prevents unexpected cylinder movement after a power interruption—useful on clamps, gates, or diverters that must hold position.
For smaller O20-32 mm cylinders the 4V100 body (Cv 0.6) is often sufficient; for larger bores or faster stroke times the 4V300 (Cv 1.65) gives more flow headroom. When replacing an existing valve, match all five points: 4V200 body, 5/2 double-solenoid function, 1/4" PT port, AC110V coil, and terminal-box entry. If you need a manifold-ready assembly, order the same code with a sub-base—the valve body itself is manifold-compatible.
Quick checklist

- 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 4V220-08C Solenoid Valve, 5/2-way, PT1/4, AC110V, terminal entry (4V22008C) FAQ
The double-solenoid memory holds the spool in its last position, which keeps the cylinder ports pressurized or exhausted as they were. However, this alone does not guarantee a suspended load will not drift—cylinder seal leakage or hose elasticity can still cause movement. For vertical load-holding, add a pilot-operated check valve at the cylinder ports or a mechanical brake.
Yes. The AC110V coil (code C) is rated for 50/60 Hz operation and draws 4.5 VA inrush. The terminal-box entry accepts standard conduit or cable-gland wiring, and the B-class insulation handles the normal temperature rise of an AC-energised coil.
