Airtac 3V2M Solenoid Valve 3V2MNOAI-12F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOAI-12F 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 3V2M Solenoid Valve 3V2MNOAI-12F
The 3V2MNOAI-12F is a matched 12-station bank of normally open 3/2 solenoid valves. Every station is direct acting with a single coil and spring return, built on a coaxial poppet that seals cleanly against its seat. Because the valves mount on a dedicated base, one air feed and one wiring loom serve the entire row.
Normally open means each outlet is fed with air while its coil is off; energising a coil vents that station. The dedicated base gasket sets this state, and turning it over does not swap NO to NC, so the configuration must be ordered correctly. Coils are AC220V at 7 VA each, entered by flying lead rather than a DIN socket, and the body carries an IP65 (DIN 40050) rating.

| 3V2M | 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. |
| NO | Normally open: air passes 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. |
| 12F | 12 stations in one assembly, centralised exhaust. |
| 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 3V2M Solenoid Valve 3V2MNOAI-12F Is Used
Carton printer web blow-off
Twelve NO jets on a corrugated printing line keep air on the web guide continuously; each solenoid cuts its own jet only when the PLC commands it.
Bottle-rail rinse clearing
Over a PET bottling conveyor, all 12 nozzles blow rinse water from the rail while de-energised; energising a station vents it for a dry lane.
Welding fixture clamp bank
In a robot welding cell with 12 toggle clamps, a power cut leaves the clamps holding, because NO stations only vent when their coil is energised.
Is the Airtac 3V2M Solenoid Valve 3V2MNOAI-12F the Right Part?
Flow through the base is the trade-off for manifold density: each port is Cv 0.1, so if one station needs more punch, fit an individual 3V2 (Cv 0.18 at 1/8 in, Cv 0.19 at 1/4 in, both vacuum rated) or step to 3V3 for Cv 0.62 at 1/4 in. Where the duty is light, a 3V1 coil at 3.0 W DC saves panel load. Need a double-acting cylinder moved? That takes a 5-port AirTAC 4V valve, not this 3/2 set.
Order by five points: initial state NO, AC220V coil, flying-lead entry, 12 stations and centralised exhaust, with PT as the standard thread (G and NPT are order options). A NO unit cannot be turned into NC after purchase.
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 Blank any unused station on the base before pressurising.
- check Wiring by qualified personnel, per AirTAC documentation.
Airtac 3V2M Solenoid Valve 3V2MNOAI-12F FAQ
Each station is a 3/2 direct-acting valve with Cv 0.1 flow coefficient, 0-0.8 MPa operating pressure, -20 to 70 C media temperature and IP65 protection (DIN 40050). The AC220V coils draw 7 VA each, so all 12 energised together ask about 84 VA from the transformer. Air should be filtered to 40 um or finer; lubrication is not required.
No. The initial state is fixed by how the valve is built and by the dedicated base gasket, and flipping that gasket does not convert NO to NC. Order the state your machine needs up front; this 12-station set is normally open.
