Airtac 3V2 Solenoid Valve 3V206NCFI
The AirTAC Airtac 3V2 Solenoid Valve 3V206NCFI 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 voltageDC12V

About the Airtac 3V2 Solenoid Valve 3V206NCFI
The 3V206NCFI is the flying-lead version of the 3V2 in NC, DC12V, 1/8in: a pre-wired lead-out replaces the DIN socket, so the coil connection arrives on the valve and no separate plug goes on the bill of materials. Normally closed means the coaxial poppet stays shut on its spring, venting the outlet until the coil pulls it open.
The 1/8in PT port flows Cv 0.18 (3.2 mm2). Coil draw is 7.0 W on DC12V, sealing is IP65, and the body is rated for vacuum service from -102.2 kPa to 0.1 MPa. Order this genuine AirTAC valve by RFQ.

Model Code: Airtac 3V2 Solenoid Valve 3V206NCFI
| 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. |
| DC12V | 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 3V206NCFI Is Used
Bench-top leak rigs
Test benches for fittings and hoses use the lead-out wires to take the valve straight into a 12V control relay, with the NC state isolating the part under test between cycles.
Vacuum end-of-arm tooling
A cobot gripper switching suction down to -102.2 kPa benefits from flexible lead routing on a moving arm, where a rigid DIN plug can work loose over thousands of cycles.
Trailer auxiliary circuits
On delivery-vehicle auxiliary controls the DC12V coil matches the truck battery, and the NC default vents the actuator line whenever the ignition is off.
Is the Airtac 3V2 Solenoid Valve 3V206NCFI the Right Part?
Confirm five things before ordering: PT1/8 thread (G and NPT available to order), normally closed start, DC12V coil, flying-lead entry, and any vacuum duty. If leads are not wanted, the plain 3V206NCF takes a DIN plug instead. Where coil power is the constraint, 3V1 drops to 3.0 W on DC24V but loses the vacuum rating; where valve count per panel matters more than flow, 3V2M sits on a shared base at Cv 0.1.
This 3V2 stays the pick when an independently plumbed valve at Cv 0.18 is needed. For much larger flow, 3V3 offers Cv 0.62 on a 1/4in port and keeps the vacuum rating. Double-acting cylinders belong on the 5-port AirTAC 4V range.
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 3V206NCFI FAQ
Effective area and Cv are 3.2 mm2 / 0.18 on the 1/8in 3V206 body and 3.4 mm2 / 0.19 on the 1/4in 3V208. Operating pressure 0-0.8 MPa; vacuum service -102.2 kPa to 0.1 MPa; temperature -20 to 70 C; coil power 7.0 W DC or 7 VA AC; ingress protection IP65 (DIN 40050). Air must be filtered to 40 um or finer and needs no lubrication.
Yes - the 3V2 body is rated from -102.2 kPa to 0.1 MPa for negative-pressure service, a rating the 3V1 and 3V2M families do not carry. The source gives no vacuum flow figure, so confirm performance from the datasheet before sizing a vacuum application.
