The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCEI-16F 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-16F is a factory-built manifold assembly: sixteen 3V2M NC valve bodies carried on a dedicated 16-station base. Each valve is a 3/2 direct-acting unit with a single AC110V solenoid, spring return and a coaxial shut-off poppet, working on PT1/8 ports. Until a coil is energised, that station's outlet has no air.
Because all sixteen valves share one supply gallery and one wiring run, commissioning and fault-finding stay simple: one air connection to check and one harness to test. Each coil draws 7 VA, so an assembly with all sixteen stations energised at once needs roughly 112 VA from your AC110V control circuit - size the transformer for that worst case. A manual override on every body helps during set-up.

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. |
| 16F | 16 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 pallet fixture with sixteen spring-return clamp cylinders is fed and vented valve by valve from one base, each cylinder staying vented until its NC coil energises.
Flying leads run straight to the carton sealer's junction box, so a 16-station build avoids sixteen separate DIN connectors while one common exhaust keeps the cabinet tidy.
A parcel sorter drives sixteen diverter gates from one manifold; centralised exhaust keeps released air and noise away from the products on the belt.
Match five points before ordering: initial state (NC here, fixed for life), coil voltage (AC110V), electrical entry (flying lead), station count (16) and exhaust type (centralised), with PT thread as standard and G or NPT available to order. NC and NO cannot be swapped after purchase - the base gasket orientation does not convert the state, so order the state each station needs.
At Cv 0.1 per station this manifold favours density over flow. If one station needs more, fit an individual 3V2 valve (Cv 0.18 at 1/8 in, Cv 0.19 at 1/4 in, vacuum-rated) or a 3V3 (Cv 0.62, 1/4 in, vacuum-rated); choose 3V1 at 3.0 W DC when the duty is light. For double-acting cylinders you need the 5-port AirTAC 4V series instead.
Confirm before you order
Each of the 16 valves has a flow coefficient Cv 0.1, works at 0-0.8 MPa and -20 to 70 C, draws 7 VA on AC110V and meets IP65 (DIN 40050). Air must be filtered to 40 um or finer; lubrication is not required.
No. The initial state is built into the valve when ordered, and the 3V2M base gasket cannot be flipped or adjusted to change NC into NO. If any station must pass air while de-energised, order that station as an NO valve from the start.
