Airtac 3V2M Solenoid Valve 3V2MNOFI-9F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOFI-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 3V2MNOFI-9F
One air feed, one wiring harness, nine switching points - the 3V2MNOFI-9F is a complete 3V2M manifold assembly built around normally open 3/2 valves. Every valve is direct-acting with a spring-return, single-solenoid coaxial poppet, and because the state is normally open all nine outlets are fed while idle and vent only when their coils are powered.
The I suffix means flying-lead entry: each coil carries its own lead-out wires in place of a DIN plug, which shortens panel wiring and removes seats that can shake free. Coils run on DC12V at 7.0 W, so a worst case of all nine energised draws about 63 W - close to 5.3 A at 12 V. Each position flows Cv 0.1, the shared supply makes fault-finding a matter of tracing one circuit at a time, and exhausts combine into one centralised port.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNOFI-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. |
| DC12V | 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 3V2MNOFI-9F Is Used
Cup ejection jets
Nine blow-off jets clear formed cups from a thermoformer's mould pockets; being normally open, the jets purge continuously and only stop when a coil is powered.
Sample-chamber purge rig
A university test rig purges nine environmental chambers with filtered dry air; the flying leads tie into a low-voltage bench supply behind a shared 40 um filter.
Trailer docking clamps
A 12 V vehicle supply powers the coils, and each clamp cylinder stays applied while idle, releasing only when the driver energises the vent coil at the pendant.
Is the Airtac 3V2M Solenoid Valve 3V2MNOFI-9F the Right Part?
Size the flow first. At Cv 0.1 per station the base path is the price of manifold density; an individually ported 3V2 reaches Cv 0.18 (1/8 in) or 0.19 (1/4 in), 3V3 tops the 3V range at Cv 0.62, and 3V1 saves coil power at 3.0 W DC when the switching duty is small. If any actuator in the system is double-acting, it needs a 5-port valve from the AirTAC 4V series instead.
Then confirm the exact build you want: normally open initial state (which cannot be changed after purchase by any means, including flipping the base gasket), DC12V coil, flying-lead wiring rather than a DIN plug, nine stations, centralised exhaust, and the thread - PT as the family standard, with G and NPT available to order.
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 3V2MNOFI-9F FAQ
Cv 0.1 flow coefficient per station, 0-0.8 MPa (0-114 psi) operating pressure, -20 to 70 C media temperature, IP65 (DIN 40050) coil protection and PT1/8 ports. Coil power is 7.0 W on DC (AC versions in the family draw 7 VA); with all nine DC12V coils energised the assembly needs about 63 W, close to 5.3 A at 12 V - size the supply for that worst case.
No. A 3/2 valve has three ports and two states: it either feeds the outlet or vents it, which suits single-acting spring-return cylinders, clamping, blow duty and pilot service. Double-acting actuators need a 5-port valve - use the AirTAC 4V series for those.
