Airtac 3V2M Solenoid Valve 3V2MNCAI
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCAI 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
3V2MNCAI is the valve body of the 3V2M family in NC form, with an AC220V 7 VA coil on a flying lead rather than a DIN socket - the pre-wired lead-out drops straight onto a terminal strip where there is no room for a plug. The 3/2 body is direct-acting, spring return, coaxial shut-off, Cv 0.1, IP65, with a manual override for setup.
A 3V2M body only works on its dedicated base, so add the base block separately to get a working valve; the shared-supply, shared-wiring layout also lets you expand the manifold later. Order the NC state deliberately: the special base gasket cannot be turned over to convert NC to NO, so the initial state is fixed at purchase.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNCAI
| 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. |
| 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 Is Used
Retrofit wiring in an older control panel
The flying lead lands straight on existing terminal strips where DIN plugs will not fit, keeping the retrofit tidy without adapter sockets.
Sample transfer on an analytical instrument
A compact 3/2 body switches air to a small single-acting cylinder that lifts or clamps a sample tray during analysis.
Pilot stage for a large diaphragm valve
Cv 0.1 is enough to pressurise or vent a diaphragm actuator chamber, letting one small coil control a much bigger process valve.
Is the Airtac 3V2M Solenoid Valve 3V2MNCAI the Right Part?
As a single body this is the density play: Cv 0.1 keeps many stations close together at the cost of per-station flow. Where a point needs more, use an individual 3V2 (Cv 0.18 at 1/8, Cv 0.19 at 1/4, vacuum-rated) or a 3V3 (Cv 0.62, 1/4, vacuum-rated) for the highest flow in the range; 3V1 at 3.0 W DC covers low-power duties. This SKU is fixed as NC, AC220V, flying lead - none of these can be changed after purchase, and flipping the dedicated base gasket does not convert NC to NO. Match the state, voltage, entry and thread (PT standard; G or NPT to order), and choose the base station count and exhaust type before ordering. For double-acting cylinders, move to the AirTAC 4V series instead of any 3-port 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 Wiring by qualified personnel, per AirTAC documentation.
Airtac 3V2M Solenoid Valve 3V2MNCAI FAQ
3/2 function, direct-acting and spring return; Cv 0.1; operating pressure 0-0.8 MPa (0-114 psi); temperature -20 to 70 C; AC220V coil at 7 VA (DC 3V2M coils are 7.0 W); IP65 to DIN 40050; PT1/8 port; air filtered to 40 um or finer, no lubrication required.
The I entry gives you a pre-wired lead-out instead of a DIN socket, useful on crowded terminal strips. The NC state cannot be converted afterwards: flipping the dedicated 3V2M base gasket does not turn NC into NO, so if you need a valve that passes air while de-energised, order the NO version from the start.
