The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCEI-10F 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.
The 3V2MNCEI-10F puts ten 3/2 normally closed valves on a single 10-station 3V2M base. Each body is direct-acting, single solenoid, spring return, with a coaxial shut-off poppet; each carries an AC24V coil with a pre-wired flying lead, so all ten valves can share one wiring loom back to the panel. The base exhausts centrally, sending all ten stations to one common exhaust point.
Do the power budget before you pick the transformer: ten AC24V coils at 7 VA each total 70 VA, roughly 2.9 A at 24 V, if every station is energised at once - size the control transformer for that worst case. Flow per station is Cv 0.1, ports are PT1/8, and the IP65 (DIN 40050) construction tolerates -20 to 70 C.

Figures follow the official AirTAC 3V2M catalogue. Confirm coil voltage and thread (PT / NPT / G) against the product label before wiring.
| 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. |
| AC24V | Coil voltage. A = AC220V, B = DC24V, C = AC110V, E = AC24V, F = DC12V. |
| I | Electrical entry: I = flying lead, otherwise a DIN plug. |
| 10F | 10 stations in one assembly, centralised exhaust. |
| PT | Port thread. PT ships from stock; G and NPT are available to order. |
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.
A car-body welding fixture with ten clamp positions runs every clamp from one 10-station manifold fed by a single AC24V control circuit.
Ten pallet clamps on an SMT line index in sequence, each switched by its own NC valve while sharing the same supply and wiring loom.
Stopper pins along a parcel sortation conveyor pop up under PLC control, each driven by one normally closed valve on the shared block.
Choose this 10-station 3V2M assembly when you want ten switching points packed onto one manifold with one supply and one wiring run; the cost is flow, since Cv 0.1 is lower than a valve mounted on its own ports. Where a station needs more, use an individual 3V2 (Cv 0.18 at 1/8 inch, 0.19 at 1/4 inch, vacuum-rated - unlike the 3V2M) or the 3V3 at Cv 0.62 on 1/4 inch; for light duty at minimum power, 3V1 runs on 3.0 W DC. For double-acting cylinders, move to the AirTAC 4V series.
Match five things to your machine: initial state (NC - not convertible later, gasket flipping does nothing), voltage AC24V, entry (flying lead, I suffix), station count 10, and centralised exhaust. PT is the standard thread here; G and NPT are order-time options.
Confirm before you order
Ten 3/2 NC valves, AC24V, 7 VA per coil (70 VA total energised), flying-lead entry, Cv 0.1, 0-0.8 MPa (0-114 psi) pressure, -20 to 70 C, IP65 to DIN 40050, PT1/8 ports, centralised exhaust, air filtered to 40 um or finer, manual override on each valve.
All ten valves vent into one shared exhaust path in the base instead of each station having its own port. It keeps the manifold compact and needs only one silencer point, but stations cannot be individually ducted or monitored - choose a D (independent exhaust) base if each station needs its own vent.
