Airtac 3V2M Solenoid Valve 3V2MNOAI-8F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOAI-8F 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-8F
The 3V2MNOAI-8F arrives as a complete eight-station block: eight 3/2 normally open valve bodies pre-mounted on a dedicated 8F base, wired with flying leads and fed from a single AC220V supply. Every valve is normally open, so compressed air flows to each outlet until its solenoid is energised - useful where a machine must pass air at rest, for example venting or blowing between cycles.
Each valve is direct-acting with a spring return and a coaxial poppet shut-off, rated Cv 0.1 and IP65 (DIN 40050). Because all eight bodies sit on one base, they share one air supply and one wiring harness, so a fault on any station is found faster than tracing eight separate valves.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNOAI-8F
| 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. |
| 8F | 8 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-8F Is Used
Packaging line hold-down clamp array
Eight NO valves keep spring-return clamps pressurised between cycles on a carton sealing machine, dropping each clamp only when the PLC energises that station during pallet ejection.
Conveyor divert air-jet bank
A row of blow nozzles above a belt sorter stays on at rest; each NO station cuts its jet only when energised, letting the shared AC220V supply feed all eight from one manifold.
Paint booth purge manifolds
Continuous purge air to booth nozzles runs through eight normally open ports, with one energised shut-off per zone for maintenance without disturbing the other seven.
Is the Airtac 3V2M Solenoid Valve 3V2MNOAI-8F the Right Part?
Confirm the initial state before ordering: NO here means air passes until energised, and this cannot be converted afterwards - the dedicated base gasket cannot be flipped to change NC to NO or the reverse. If a station needs more flow than Cv 0.1, move that circuit to an individual 3V2 (Cv 0.18 at 1/8 inch, 0.19 at 1/4 inch, vacuum-rated) or to 3V3 (Cv 0.62, 1/4 inch). For small duties, 3V1 draws only 3.0 W on DC.
Match five points: initial state (NO), coil voltage (AC220V here), electrical entry (flying lead, not a DIN socket), station count (8F), and exhaust (centralised, all stations vent through one port). PT thread is standard on this family; G and NPT are catalogue options to order. For a double-acting cylinder you need a 5-port AirTAC 4V valve, not this 3/2 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-8F FAQ
Eight normally open 3/2 valves, AC220V coils at 7 VA each, flying-lead entry, Cv 0.1 per valve, operating pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, IP65 (DIN 40050), PT1/8 ports on a centralised-exhaust 8F base. Full datasheet available on RFQ.
The I entry replaces each DIN socket with a pre-wired lead-out, so the eight stations land on terminal strips without ordering separate plugs - handy in a controlled AC220V panel. If your panel prefers plug-in coils, order the non-I version with DIN sockets instead.
