The AirTAC Airtac 4V Solenoid Valves 4V220-08CG is a genuine 5/2-way double solenoid (memory) solenoid valve with 08CG ports and an effective area of 17.0 mm² (Cv 1.0). It is an internally piloted spool valve that directs compressed air to double-acting cylinders and actuators.
The AirTAC 4V220-08CG is a 5/2-way double-solenoid valve built on the 4V200 body, configured with parallel G-thread (BSPP) ports and a pre-wired grommet entry for its AC110V coil. It directs compressed air to double-acting cylinders and actuators, with a memory function that keeps the spool in its last pulsed position even when power is removed—no holding current needed.
With an effective flow area of 17.0 mm² (Cv 1.0) and a maximum cycling rate of 5 times per second, this valve suits cylinders in the O32-50 mm range. The 0.5-metre flying lead simplifies wiring into tight cabinets, and the AC110V coil draws 4.5 VA. Response time is 0.05 seconds or less, and the IP65-rated aluminium body handles 0.15-0.8 MPa operating pressure.

Size the valve so effective area / Cv is not the bottleneck for your cylinder bore and speed. Undersized valves slow the actuator. Note 5/3 (center) versions have a smaller effective area than the 5/2 of the same body size.

Ideal for carton-closing and case-erecting stations where a double-solenoid valve holds the cylinder in place between cycles without needing a continuous signal, simplifying the control logic.
Controls a double-acting clamp that must stay engaged after an emergency stop. The memory function keeps pressure on the workpiece, and the AC110V coil fits standard shop power.
The 0.5 m grommet lead and 110 V AC coil wire directly into relay-logic panels, eliminating the need for a separate DC supply. The BSPP ports seal reliably on parallel-thread manifolds.
Choose the 4V220-08CG when your circuit needs a 5/2 valve that remembers its position after a signal pulse, avoiding the constant power draw of a spring-return model. Its 1/4-inch BSPP ports match common pneumatic fittings, and the AC110V grommet entry suits machines where a terminal box is impractical. If you are driving smaller cylinders below O32 mm, the 4V100 series with Cv 0.6 may be a better fit; for larger bores or faster strokes above 50 mm, step up to the 4V300 series at Cv 1.65. When replacing an existing valve, match the body size (4V200), the double-solenoid function, the parallel thread, and the 110 V AC coil with flying-lead connection.
Quick checklist
With a Cv of 1.0 and 17.0 mm² effective area, it pairs well with double-acting cylinders from about 32 mm to 50 mm bore. For a 63 mm cylinder needing higher speed, consider the 4V300 series (Cv 1.65).
No. The 4V220 is a double-solenoid design with a memory spool. A brief pulse to either coil shifts it, and it holds that position mechanically when power is lost. It is not magnetically latched.
