Airtac 3V2M Solenoid Valve 3V2MNCFI-9F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCFI-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 3V2MNCFI-9F
Fault-finding is the quiet benefit of the 3V2MNCFI-9F. Nine NC 3/2 valve sections hang off one base with a single shared supply and one wiring run, so a dead station stands out immediately against eight working neighbours instead of hiding among nine separately plumbed valves. Each section is a direct-acting, single-solenoid, spring-return coaxial poppet, and a manual override on every body lets you walk the machine through its cycle during setup.
Nine DC12V coils at 7.0 W draw 63 W - about 5.25 A - if all are energised together, so size the 12 V supply for that worst case. Flow per station is Cv 0.1 through the base, coils are sealed to IP65 (DIN 40050), and every coil is wired through its own pre-terminated flying lead rather than a DIN socket.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNCFI-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. |
| 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. |
| 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 3V2MNCFI-9F Is Used
Warehouse divert gates
Nine divert gates on a sorting spur, one NC station per gate, each releasing to its spring position the moment its coil is de-energised.
Thread cutters on a winder
Pneumatic thread cutters along a textile winding frame, every cutter fed from the shared supply and vented through the single common exhaust.
Guard-line spring stoppers
Spring-applied stoppers on a guarded conveyor line, held open by NC stations so any power loss drops every stopper into the safe position.
Is the Airtac 3V2M Solenoid Valve 3V2MNCFI-9F the Right Part?
Confirm the five order points: initial state NC (it cannot be altered afterwards - order NO up front if any position needs a passing de-energised state), coil DC12V, flying-lead entry, nine stations on the centralised-exhaust base, and PT1/8 thread as the standard for this family with G and NPT orderable. Expansion is easy: 3V2M stations combine freely and accept mixed valve types, so a tenth section is one more valve and base order, not a redesign. Where a station outgrows Cv 0.1, give it a standalone 3V2 (Cv 0.18 at 1/8 in, 0.19 at 1/4 in, vacuum-rated) or a 3V3 at Cv 0.62; keep power-sensitive duties on 3V1 at 3.0 W DC. Double-acting cylinders require the 5-port AirTAC 4V 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 3V2MNCFI-9F FAQ
Nine 3/2 direct-acting, single-solenoid, spring-return coaxial poppet valves on one base: Cv 0.1 each, operating pressure 0-0.8 MPa, temperature -20 to 70 C, DC12V coil power 7.0 W per station, protection IP65 (DIN 40050). Ports are PT1/8 with G and NPT to order; the medium is air filtered to 40 um or finer, with no lubrication needed.
Yes - 3V2M stations combine and expand freely and valve types can be mixed on one base, so adding a tenth section is an order for another valve and base, not a re-plumb. Two things are fixed, though: the NC initial state of the valves supplied is never convertible after purchase, and 3V2M has no vacuum rating - use the 3V2 or 3V3 series where negative pressure is involved.
