Airtac 3V2M Solenoid Valve 3V2MNOAI-9F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOAI-9F 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-9F
Nine identical 3/2 normally open poppet valves share one 9F base in this complete assembly. Supply air enters once, wiring lands once, and each station vents through the single centralised exhaust port. The coils run on AC220V at 7 VA and connect through flying leads rather than plug-in sockets.
Normally open logic suits circuits where air must be present until a signal arrives - clamps that stay gripped, jets that stay on. Each valve is direct-acting, spring return, Cv 0.1, IP65 to DIN 40050, and accepts filtered air through a 40 um or finer element with no lubrication needed.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNOAI-9F
| 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. |
| 9F | 9 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-9F Is Used
Robotic gripper jaw pilot bank
Nine NO stations pilot nine gripper jaws on a robot end effector that must hold vacuum-tight grip pressure whenever control power is lost, since air passes until energised.
Lab autoclave door seal vents
Seal-inflate lines on a laboratory steriliser stay pressurised at rest; each of the nine NO valves vents its circuit only during the door-unlock step.
Tile press ejection pin control
A nine-cavity ceramic press keeps ejector pins blown clear between presses, with each normally open station cut per cavity as the PLC cycles the mould.
Is the Airtac 3V2M Solenoid Valve 3V2MNOAI-9F the Right Part?
The ninth station is the practical reason to pick this code over the 8F: if your sequence list has grown by one output, you add one valve to one base instead of mounting a standalone valve beside the bank. Remember the flow ceiling - Cv 0.1 per station because air routes through the base - so a hungry circuit belongs on an individual 3V2 (Cv 0.18-0.19) or 3V3 (Cv 0.62).
Check five things against your drawing: state NO (irreversible after purchase - the base gasket cannot be flipped to change it), AC220V coil, flying-lead entry, 9 stations, centralised exhaust. Thread is PT as standard, with G and NPT orderable. A double-acting cylinder needs the AirTAC 4V series, not a 3/2 valve.
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-9F FAQ
Yes: nine NO 3/2 stations, AC220V at 7 VA per coil, flying-lead entry, Cv 0.1 each, 0-0.8 MPa (0-114 psi) operating pressure, -20 to 70 C, IP65 (DIN 40050), PT1/8 with G and NPT as order options, centralised exhaust on the 9F base.
One air drop and one wiring run feed all nine valves, so leak-down and electrical faults are isolated per station on a single manifold rather than across nine separately plumbed valves. Manual overrides on each body let you stroke any station by hand during setup.
