Airtac 3V2M Solenoid Valve 3V2MNCFI-5F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCFI-5F 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-5F
Five normally closed 3/2 valves share one 3V2M base in the 3V2MNCFI-5F, forming a five-circuit 12 V block wired on flying leads. Every valve is direct-acting with spring return and coaxial shut-off sealing, so each outlet sits vented until its coil is energised - the behaviour you want where an unpowered machine must be safe.
Check the power budget before you build: five DC coils at 7.0 W each total about 35 W, near 2.9 A at 12 V with all stations on, so the worst-case figure decides the supply. One air feed serves all five stations and exhaust is centralised to a single port, while the shared wiring panel keeps diagnostics simple. Cv 0.1 per station and manual overrides on every valve support quick setup. The NC state is chosen at ordering and cannot be reversed or converted afterwards.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNCFI-5F
| 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. |
| 5F | 5 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-5F Is Used
Bottling line gate control
Five NC valves on one 12 V manifold drive spring-return gates and stoppers along a bottling conveyor, sequenced from a PLC output card.
Ceramic press safety interlocks
Five 12 V flying-lead circuits release guard interlock cylinders on a ceramic press, all vented safely at power-off through the central exhaust.
Mixer drum choke actuators
A five-station 3V2M group toggles choke flaps on a batching mixer, tuned circuit by circuit without disturbing the shared supply or wiring.
Is the Airtac 3V2M Solenoid Valve 3V2MNCFI-5F the Right Part?
Before ordering, settle all five points: initial state (NC, fixed for life - no gasket flip or field trick changes it), DC12V voltage, flying-lead entry, 5 stations, centralised exhaust, plus thread choice where PT is the family standard and G or NPT are options written into the order.
This manifold favours density over flow: Cv 0.1 per valve against Cv 0.18-0.19 for an individual 3V2 and Cv 0.62 for a 3V3 at 1/4 inch, both of which are vacuum-rated where the 3V2M is not. For small-duty circuits the 3.0 W DC 3V1 body cuts coil load. If the actuator is a double-acting cylinder, specify the AirTAC 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 3V2MNCFI-5F FAQ
Five NC 3/2 valves, direct-acting, single solenoid, spring return, coaxial shut-off, on one manifold base. Cv 0.1 per valve, 0-0.8 MPa, -20 to 70 C, DC12V coils at 7.0 W each - about 35 W or roughly 2.9 A at 12 V if all five run together. IP65 (DIN 40050), PT1/8 ports, flying-lead entry, centralised exhaust, manual override per station, air filtered to 40 um or finer.
With no D code in the order, exhaust is centralised: all five stations vent through one shared port, which simplifies ducting and lets you fit a single silencer. Independent per-station exhaust is available on other 3V2M codes ordered with the D suffix. Air quality still matters for every station - use filtered air of 40 um or better, and no lubrication is required.
