Airtac 3V2 Solenoid Valve 3V206NCCI
The AirTAC Airtac 3V2 Solenoid Valve 3V206NCCI 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.

- Initial stateNormally closed
- Port size1/8 in
- Coil voltageAC110V

About the Airtac 3V2 Solenoid Valve 3V206NCCI
Order the 3V206NCCI when you want the 3V2 poppet valve delivered with flying leads instead of a DIN socket: the pre-wired lead-out terminates the 110V AC coil so installers connect terminals directly, with no plug to stock or seat. Functionally it is the normally closed 1/8 inch PT version - outlet vented until the coil is energised.
It is a direct-acting, spring-return 3/2 rated 0-0.8 MPa and, less obviously, usable down to -102.2 kPa on vacuum lines. Each port passes Cv 0.18 (3.2 mm2). AirTAC fits a manual override so the line can be fed by hand during setup.

Model Code: Airtac 3V2 Solenoid Valve 3V206NCCI
| 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. |
| AC110V | 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 3V206NCCI Is Used
Wired-in valve banks in tight cabinets
Electrical enclosures with no DIN socket clearance take the lead-out version; the flying leads run to terminal blocks where plug bodies would foul adjacent valves.
Vacuum ejector line switching
A normally closed 3/2 sits between vacuum generator and suction pad on a small gantry, holding the line vented when idle within the -102.2 kPa rating.
Single-acting punch cylinder control
The AC110V coil is driven from a machine PLC relay output to advance a spring-return punch; losing power retracts and vents the cylinder safely.
Is the Airtac 3V2 Solenoid Valve 3V206NCCI the Right Part?
The five-point check: 1/8 inch port and PT thread (G or NPT as an order option), normally closed state, AC110V coil, flying-lead entry rather than DIN, and any vacuum involvement - this body carries the -102.2 kPa to 0.1 MPa rating. Prefer a plug-in coil connector for quick swaps? Then the non-I variant with DIN entry is the better pick.
For tighter power budgets, 3V1 on DC24V draws 3.0 W against 7 VA here; for denser multi-station manifolding, 3V2M trades flow (Cv 0.1) for footprint. Need a real jump in flow? 3V3 at Cv 0.62. Double-acting cylinder in the spec? Route it to 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 3V206NCCI FAQ
Per-port flow: 3V206 (1/8in) is 3.2 mm2 effective area, Cv 0.18; 3V208 (1/4in) is 3.4 mm2, Cv 0.19. Operating pressure is 0-0.8 MPa (0-114 psi), with vacuum service rated -102.2 kPa to 0.1 MPa. Temperature range is -20 to 70 C. Coil power is 7 VA on AC and 7.0 W on DC. Coil protection is IP65 (DIN 40050).
Yes - the 3V2 poppet body is rated from -102.2 kPa to 0.1 MPa, so it can sit in negative-pressure circuits, which the 3V1 and 3V2M bodies cannot. The rating covers the operating envelope only; confirm vacuum flow performance for your specific setup from the datasheet or via RFQ.
