Airtac 3V2M Solenoid Valve 3V2MNCFI-8F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCFI-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 3V2MNCFI-8F
Eight stations on one machined base is where the 3V2M layout earns its keep - and where its single compromise shows. Routing air through the base holds each valve to Cv 0.1, lower than an individually ported 3V2, so the 3V2MNCFI-8F is the right choice when panel space and wiring count matter more than per-station flow. Each of the eight sections is normally closed, direct-acting and spring-return, with a coaxial poppet for tight shut-off.
The DC12V coils come with flying leads fitted, eight pre-terminated lead-out wires feeding one common harness off a single supply. Budget the power honestly: 7.0 W per coil means 56 W, roughly 4.7 A at 12 V, with all eight energised at once. Coil sealing is IP65 (DIN 40050) and every body carries a manual override for stepping through the cycle.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNCFI-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. |
| 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. |
| 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 3V2MNCFI-8F Is Used
Sorter divert modules
Pop-up diverter rollers in a small parcel sorter, one NC station per module, all supplied and wired from a single point at the end of the frame.
Jig clamps on a welding bench
Locating clamps on a fabrication jig, each one held by a spring-return cylinder fed from its own station and released on power loss.
CNC chip blow-off
Gated air nozzles clearing chips from a machining envelope, energised only during the blow-off step because the NC sections stay shut otherwise.
Is the Airtac 3V2M Solenoid Valve 3V2MNCFI-8F the Right Part?
Five decisions set this order: NC initial state (fixed at purchase - the base gasket cannot be flipped to change it, so confirm NO up front if you need air to pass while de-energised), DC12V coil, flying-lead entry, eight stations, and centralised exhaust on the blank -8F code (independent per-station exhaust is the -8FD variant). Thread is PT1/8 as standard; G and NPT are catalogue options. Compare flow openly: Cv 0.1 here versus Cv 0.18 at 1/8 in or 0.19 at 1/4 in on a standalone 3V2, and Cv 0.62 on a 3V3 - move a high-flow station to one of those, and drop modest duties to 3V1 at 3.0 W DC. Double-acting cylinders belong on a 5-port AirTAC 4V 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 3V2MNCFI-8F FAQ
Eight normally closed 3/2 poppet valves, direct-acting with spring return, on one shared base: Cv 0.1 per station, 0-0.8 MPa operating pressure, -20 to 70 C temperature, DC12V coils at 7.0 W each, IP65 (DIN 40050). PT1/8 ports are standard; G and NPT are order options. Air must pass a 40 um or finer filter and lubrication is not required.
No. 3V2M uses a dedicated base gasket, and reversing that gasket does not convert a valve between NC and NO; the initial state is built into the valve and must be ordered correctly. If any of the eight positions should pass air while de-energised, order those valves as NO under a separate 3V2MNO code when you place the RFQ.
