Airtac 3V2M Solenoid Valve 3V2MNCAI-3F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCAI-3F 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 3V2MNCAI-3F
3V2MNCAI-3F is the smallest complete assembly in this listing: three normally closed 3/2 valve bodies mounted on a dedicated base with a single PT1/8 supply port, wired through flying leads to AC220V. Each coil takes 7 VA, so the whole panel draws just 21 VA when all three are held on - easy to run from a small control transformer.
Start with three stations and grow later: 3V2M bodies combine and expand freely on the same base family, and mixed valve types can share the block. Direct-acting poppet construction with spring return means the valve needs no minimum pressure to shift. As with every 3V2M, the NC state must be ordered correctly because it cannot be converted afterwards.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNCAI-3F
| 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. |
| AC220V | Coil voltage. A = AC220V, B = DC24V, C = AC110V, E = AC24V, F = DC12V. |
| I | Electrical entry: I = flying lead, otherwise a DIN plug. |
| 3F | 3 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 3V2MNCAI-3F Is Used
Laboratory wash-rack valves
Three wash, rinse and drain functions on a lab glassware washer share one compact NC base.
Bench-top clamping jig
Three pneumatic swing clamps on a machine-shop jig switched from one transformer and one supply line.
Trailer dock-door interlock
Three lock, seal-check and gate functions at a loading dock run from one small NC manifold.
Is the Airtac 3V2M Solenoid Valve 3V2MNCAI-3F the Right Part?
Size this 3-station assembly when Cv 0.1 per station is enough; a station that stalls on flow should move to an individual 3V2 valve (Cv 0.18 at 1/8, 0.19 at 1/4, also vacuum rated) or to 3V3 (Cv 0.62, 1/4) for the top of the range, while 3V1 (3.0 W DC) covers small low-power duties. Lock in the five order points: NC or NO initial state, coil voltage, DIN plug or flying-lead entry, number of stations, and centralised or independent exhaust plus thread (PT standard, G or NPT to order). The NC state cannot be swapped later. For a double-acting cylinder, step to the 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 3V2MNCAI-3F FAQ
Cv 0.1 per station, 0-0.8 MPa (0-114 psi) working pressure, -20 to 70 C, 7 VA per AC220V coil (21 VA for three), IP65 protection to DIN 40050 and PT1/8 ports with air filtered to 40 um or better.
Each 3/2 station either feeds or vents one outlet, so it suits single-acting spring-return cylinders, on/off blow nozzles, clamps and pilot duty - never a double-acting cylinder, which needs a 5-port AirTAC 4V valve. Use NO bodies if a line must pass air while off, and order that state up front because it cannot be changed afterwards.
