Airtac 3V2M Solenoid Valve 3V2MNOFI-4F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOFI-4F 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-4F
The 3V2MNOFI-4F is a complete four-station assembly of normally open 3/2 solenoid valves. Every valve passes air from supply to outlet until its coil is energised, then the spring shuts the path and vents the outlet - the reverse logic of an NC valve, so order it only where a fail-open outlet is wanted. Each valve is direct-acting with a coaxial shut-off poppet and mounts on the dedicated 4F base, giving one PT1/8 supply point and shared wiring for the whole group.
The DC12V coil draws 7.0 W, so four energised stations together ask roughly 28 W - about 2.3 A at 12 V, a figure to size the low-voltage supply around. Coils are IP65 (DIN 40050) and each valve carries a manual override for commissioning. Cv 0.1 per station suits pilot, clamp and light blow duties. Confirm any figure not published here from the datasheet before ordering.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNOFI-4F
| 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. |
| 4F | 4 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-4F Is Used
Battery-powered service cart
A 12 V mobile cart carrying pneumatic test tools runs this 4-station bank straight from a vehicle battery; flying leads suit the temporary loom and NO logic keeps vent paths open at power-off.
Blow-off nozzle array
Four NO valves feed air knives on a bottle-rinse conveyor; if the controller dies, outlets keep blowing and clear product from the line before it is stopped safely.
Capsule ejector heads
A capsule sorter drives four single-acting ejector pins from one supply point; each pin needs only a 3/2 feed-and-vent station, and the shared base keeps wiring to two leads per coil.
Is the Airtac 3V2M Solenoid Valve 3V2MNOFI-4F the Right Part?
Choose 3V2M when station count matters more than per-station flow: Cv 0.1 is the price of routing through the base, against Cv 0.18 at 1/8 in on an individual 3V2 or Cv 0.62 on a 3V3 for the highest 3V-range flow; 3V1 is the low-power pick at 3.0 W DC if the duty is small. A normally open state cannot be converted later - the dedicated base gasket does not change NC to NO - so confirm NO up front. Match every point before ordering: initial state, coil voltage (DC12V here), electrical entry (flying lead), station count (4F), exhaust type (centralised) and thread (PT standard; G or NPT on request). Double-acting cylinders 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 3V2MNOFI-4F FAQ
It is a normally open 3/2, direct-acting assembly of four valves on one base. Flow coefficient Cv 0.1 per station, operating pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, DC12V coil at 7.0 W (four energised coils together about 28 W), IP65 to DIN 40050, PT1/8 ports, air filtered to 40 um or finer.
No. The 3V2M initial state is fixed by the valve as ordered; the dedicated base gasket cannot be flipped to convert NO to NC or the reverse, and no field adjustment changes it. If a station must be normally closed, order that valve as NC.
