About the AirTAC 4V220-08F Solenoid Valve, 5/2-way, PT1/4, DC12V, terminal entry (4V22008F)
The 4V220-08F is a 5/2-way double-solenoid directional control valve built on the proven AirTAC 4V200 mid-body platform. It directs compressed air to both sides of a double-acting cylinder, and because it is a dual-coil design, the spool stays in its last-commanded position when electrical power is removed—no spring, no holding current, just a pure memory function that keeps your actuator where you left it.
This specific assembly carries a DC12V coil drawing only 2.5 W, making it a natural fit for mobile equipment, battery-backed panels, or any machine running a 12 VDC control bus. With an effective area of 17.0 mm² (Cv 1.0) and a response time of 0.05 s or less, it comfortably cycles O32–50 mm bore cylinders at up to 5 cycles per second. The aluminum-alloy body weighs 320 g, operates on filtered air from 0.15–0.8 MPa, and is rated IP65 with a terminal-box electrical entry.

Where the AirTAC 4V220-08F Solenoid Valve, 5/2-way, PT1/4, DC12V, terminal entry (4V22008F) Is Used
Packaging & Palletising
The memory spool holds a clamp or pusher in its last position during an E-stop or power cycle, preventing product damage on restart. The DC12V coil suits common packaging-machine control voltages.
Mobile Work Platforms
Runs directly from a 12 V battery system. The double-solenoid function keeps outriggers or stabilisers extended without continuous power draw, reducing battery drain during stationary work.
Assembly & Pick-and-Place
Cycles O32–50 mm actuators at up to 5 c/s with a 0.05 s response. The memory hold allows a gripper to stay closed between stations without energising a coil, simplifying the sequence logic.
Is the AirTAC 4V220-08F Solenoid Valve, 5/2-way, PT1/4, DC12V, terminal entry (4V22008F) the Right Valve?
Choose the 4V220-08F when your application needs a 5/2 valve that must hold position after a power-down event—the dual-solenoid memory spool does exactly that without any holding current. If your cylinder is smaller than O32 mm, the 4V100 series (Cv 0.6) often provides enough flow in a lighter package; for bores above O50 mm or when you need faster cylinder speeds, stepping up to the 4V300 body (Cv 1.65) cuts fill time noticeably.
This valve is also manifold-ready: you can gang multiple 4V200 units on a common base to simplify piping and reduce leak points. When replacing an existing valve, match all five key points—4V200 body size, 5/2 double-solenoid function, PT 1/4 ports, DC12V coil voltage, and terminal-box entry—to guarantee a drop-in fit.
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 4V220-08F Solenoid Valve, 5/2-way, PT1/4, DC12V, terminal entry (4V22008F) FAQ
The spool stays in the position it was last pulsed to—there is no spring to return it. This memory hold relies on balanced pressure and spool friction, not magnetism, so the cylinder remains pressurised on one side. For suspended-load safety, always add a pilot-operated check valve or mechanical brake at the cylinder ports.
Yes, the 2.5 W DC12V coil is rated for continuous duty (100% ED). However, because this is a double-solenoid valve, you only need a brief pulse to shift the spool; you can leave both coils de-energised between moves to save energy and reduce heat build-up inside the terminal box.
