Airtac 3V2M Solenoid Valve 3V2MNCF-12F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCF-12F 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 3V2MNCF-12F
Order the 3V2MNCF-12F and you receive a ready-built bank of twelve normally closed 3/2 valves on a single AirTAC manifold. Each poppet-style, direct-acting valve handles its own supply, outlet and exhaust port in a 3/2 function, returns by spring when the coil drops out, and ports at PT1/8. Until energised, every NC station holds its outlet closed and vented.
The wiring angle is where this family earns its keep: one shared supply gallery and a common wiring run replace a dozen separate fittings and cable drops, and a fault shows up station by station instead of being hunted across the machine. Twelve coils at 7.0 W each total 84 W, close to 7.0 A at 12 V, so check your supply headroom. Cv 0.1 per station reflects the flow path running through the base.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNCF-12F
| 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. |
| NC | Normally closed: no air at the outlet until the coil is energised. |
| DC12V | Coil voltage. A = AC220V, B = DC24V, C = AC110V, E = AC24V, F = DC12V. |
| — | Electrical entry: I = flying lead, otherwise a DIN plug. |
| 12F | 12 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 3V2MNCF-12F Is Used
CNC part-ejector bank
Twelve spring-return ejector pins clear machined parts one station at a time; NC valves keep every ejector vented and retracted until its coil is called.
Air blow-off between mould shots
Normally closed blow nozzles stay dead until energised, so no air is wasted through idle nozzles between injection moulding cycles.
Sensor-driven sorting gate cluster
A PLC fires individual 12 V channels to divert small parts down different chutes, with each gate handled by its own NC station.
Is the Airtac 3V2M Solenoid Valve 3V2MNCF-12F the Right Part?
Confirm five points against this code: NC initial state, DC12V coil, DIN plug entry, 12 stations and centralised exhaust (no independent-D code in the suffix). PT is the standard thread on 3V2M; G and NPT versions exist as order options.
Choose 3V2M for station density, not raw flow: Cv 0.1 is the price of routing through the manifold, while a standalone 3V2 gives Cv 0.18 at 1/8 inch and a 3V3 reaches Cv 0.62 if one circuit needs real flow. The 3V1 at 3.0 W DC suits light duty. NC cannot be reworked to NO after purchase, and double-acting cylinders belong on the 4V series instead.
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 3V2MNCF-12F FAQ
A 3/2 NC function with Cv 0.1, pressure range 0-0.8 MPa, media temperature -20 to 70 C, 7.0 W DC12V coil per station (84 W for twelve), IP65 rating, PT1/8 porting and spring return. Air must be filtered to 40 um or finer; lubrication is not needed.
No. A 3/2 valve has three ports and two states, so it feeds or vents one outlet - that suits single-acting, spring-return cylinders, blow duty and pilot duty. Double-acting cylinders need two outlet lines, which is the job of the 5-port AirTAC 4V series.
