Airtac 3V2 Solenoid Valve 3V206NCAI
The AirTAC Airtac 3V2 Solenoid Valve 3V206NCAI is a genuine 3-port 2-position (3/2) solenoid valve with 1/8 in ports. It either feeds its outlet or vents it to exhaust, which is what makes it the valve for single-acting cylinders, on/off air blow, clamping, vacuum switching and pilot duty.

About the Airtac 3V2 Solenoid Valve 3V206NCAI
The 3V206NCAI is the flying-lead variant of the 1/8in 3V2 body: instead of a DIN socket, the AC220V coil terminates in a pre-wired lead-out, so the installer splices it straight into the machine control panel without sourcing a connector. The function is unchanged - a direct-acting, spring-return 3/2 poppet that is normally closed until energised.
Flow through the PT1/8 body measures an effective area of 3.2 mm2 with Cv 0.18, and the AC coil consumes 7 VA. Coaxial shut-off construction keeps sealing tight even at low differential, and the coil assembly carries IP65 protection to DIN 40050.

Model Code: Airtac 3V2 Solenoid Valve 3V206NCAI
| 3V2 | Body — sets the flow, the coil power and whether vacuum is rated. |
|---|---|
| 1/8 in | Port size. M5, 06 = 1/8 in, 08 = 1/4 in, 10 = 3/8 in. |
| NC | Normally closed: no air at the outlet until the coil is energised. |
| AC220V | Coil voltage. A = AC220V, B = DC24V, C = AC110V, E = AC24V, F = DC12V. |
| I | Electrical entry: I = flying lead, otherwise a DIN plug. |
| PT | Port thread. PT ships from stock; G and NPT are available to order. |
What a 3/2 Valve Does
A 3/2 valve has three ports — supply, outlet and exhaust — and two states. It either feeds the outlet or vents it to exhaust, and that is the whole job.
That makes it the right valve for a single-acting (spring-return) cylinder, on/off air blow, a clamp, switching a vacuum generator or suction cup, and piloting a larger valve.
It cannot run a double-acting cylinder. A double-acting cylinder needs air alternately on two sides, which takes a 5-port valve — the AirTAC 4V series.
Where the Airtac 3V2 Solenoid Valve 3V206NCAI Is Used
Retrofit wiring on a legacy packaging line
Older cabinets have no DIN sockets, so the lead-out wire lands directly on the terminal strip - no extra connector order, no adapter block.
Vacuum-assist transfer on a bottling line
The valve opens the vacuum circuit to -102.2 kPa when energised and vents it on de-energise, releasing each bottle at the star-wheel transfer point.
Pilot stage on a large process valve
The 1/8in outlet feeds the pilot port of a bigger main valve; the normally closed state guarantees the pilot line stays exhausted until commanded.
Is the Airtac 3V2 Solenoid Valve 3V206NCAI the Right Part?
Match five things before you order: the 1/8in port on PT thread (PT is the manufacturer default here; G and NPT are options ordered as suffixes), normally closed state, AC220V voltage, the flying-lead entry, and any vacuum in the duty - this family is rated to -102.2 kPa, a rating the 3V1 and 3V2M do not carry. If your panel prefers a plug-in connector, drop the I from the code for DIN entry. Downsize to the 3V1 when small duties and low coil draw (3.0 W on DC24V) matter most, or to 3V2M at Cv 0.1 when a compact manifold beats flow. For substantially more flow, step to the 3V3 at Cv 0.62. Double-acting cylinders belong on the AirTAC 4V series.
Confirm before you order
- ✓ Port size and thread (PT from stock; G / NPT to order)
- ✓ Initial state — NC or NO, ordered up front
- ✓ Coil voltage matches your controller output
- ✓ Electrical entry — DIN plug or flying lead
- ✓ Single valve, bare base, or complete assembly
- ✓ Single-acting duty, not double-acting
Installation & Wiring Notes
- check Use clean air filtered to 40µm or finer.
- check Stay within 0-0.8 MPa (0-114 psi) operating pressure.
- check Match the coil voltage to your controller output.
- check Use the manual override to test before powering up.
- check Leave the exhaust port clear, or fit a silencer.
- check Wiring by qualified personnel, per AirTAC documentation.
Airtac 3V2 Solenoid Valve 3V206NCAI FAQ
Operating pressure is 0-0.8 MPa, with a vacuum rating of -102.2 kPa to 0.1 MPa, over -20 to 70 C. The 1/8in port gives 3.2 mm2 effective area and Cv 0.18; the 1/4in port gives 3.4 mm2 and Cv 0.19. AC coils take 7 VA and DC coils 7.0 W, and the coil is protected to IP65 (DIN 40050). Air should be filtered through a 40 um or finer element, with no lubrication required.
Decide by what must happen on power loss. A normally closed valve like the 3V206NCAI vents the outlet when de-energised, so the actuator releases - the safe choice for clamps and blow lines. A normally open version passes air until energised, which suits fail-safe venting duties. Pick the state when ordering; the body is otherwise identical.
