Airtac 3V2M Solenoid Valve 3V2MNOAI-2F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOAI-2F 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-2F
This assembly puts two normally open 3/2 valves side by side on one 2-station base. Each valve is direct-acting with a spring return and a coaxial shut-off poppet, so air reaches the outlet while the coil is off and the station vents when the 220 VAC solenoid is powered. Both coils are 7 VA, roughly 14 VA if you energise the pair together.
Flying leads instead of DIN sockets mean the two stations land on your terminal strip ready-terminated - handy in control cabinets where every millimetre of depth counts. The shared base also means one supply fitting, one exhaust path and one wiring entry for the pair, and you can bolt on extra stations later. Remember that NO versus NC is baked in by the dedicated base gasket and cannot be swapped after the valves are bought.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNOAI-2F
| 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. |
| 2F | 2 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-2F Is Used
Twin stopper gates on an assembly conveyor
Two NO stations hold spring-return stoppers up by air and vent them independently, letting the line crew release one gate at a time while the other keeps queuing parts.
Dosing heads on a small lab filler
Two single-acting dosing cylinders stay charged between shots; energising each 220 VAC coil in sequence vents its cylinder and fires a precise dispense.
Clamp-and-blow combo on a bench press
One NO valve keeps a spring clamp engaged, the second feeds a chip-clearing air jet; sharing one base halves the fittings on a crowded workbench panel.
Is the Airtac 3V2M Solenoid Valve 3V2MNOAI-2F the Right Part?
A 2F pair suits twin single-acting points that share one supply, such as opposing stops or a clamp-and-blow combo. Fix five variables before ordering: initial state (NO here), coil voltage (AC220V), electrical entry (flying lead), station count (2F) and exhaust type (centralised); PT thread is standard on this family and G or NPT can be ordered. The state cannot be converted afterwards - no gasket flip, no field change. Where a station demands more flow than Cv 0.1, move that function to an individual 3V2 (Cv 0.18 at 1/8 in, 0.19 at 1/4 in, vacuum-rated) or a 3V3 (Cv 0.62, 1/4 in, vacuum-rated); 3V1 covers light duties at 3.0 W DC. For double-acting cylinders, specify 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 Blank any unused station on the base before pressurising.
- check Wiring by qualified personnel, per AirTAC documentation.
Airtac 3V2M Solenoid Valve 3V2MNOAI-2F FAQ
Each 3/2 station feeds or vents one port, so it drives single-acting spring-return cylinders, air blow, clamping and pilot duty. It cannot drive a double-acting cylinder, which needs pressure to both sides - use the 5-port AirTAC 4V series for that.
Two 3/2 NO valves on a 2-station base: PT1/8 ports, Cv 0.1, 0-0.8 MPa, -20 to 70 C, AC220V coils at 7 VA each (14 VA both on), IP65 (DIN 40050), centralised exhaust, PT thread with G and NPT available to order.
