The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCAI-13F 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.
Thirteen stations, one base, one pair of common connections: the 3V2MNCAI-13F is a complete AC220V valve group with flying-lead coils and NC outlets that stay closed until each coil is energised. The direct-acting, spring-return, coaxial shut-off construction keeps sealing positive at every position even when only part of the bank is working.
Plan the electrics around the coil count: each station draws 7 VA, so a fully energised 13-station bank presents roughly 91 VA to the AC220V supply - size the transformer and fusing for that worst case, not for a single valve. Centralised exhaust sends all thirteen vents to one port, and a manual override on every body lets you jog a station during commissioning.

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. |
| AC220V | Coil voltage. A = AC220V, B = DC24V, C = AC110V, E = AC24V, F = DC12V. |
| I | Electrical entry: I = flying lead, otherwise a DIN plug. |
| 13F | 13 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.
Flap and case clamps on an erector release the moment power fails, because each NC valve vents its single-acting cylinder when de-energised.
Thirteen individual air jets on a winding machine are sequenced from one manifold, one supply line and one wiring loom.
Each 3/2 station pilots a bigger pneumatic actuator, with the manifold consolidating the pilot air supply and its wiring into one panel connection.
Five points define this order: NC state, AC220V, flying-lead entry, thirteen stations, centralised exhaust, plus the PT thread (G and NPT are catalogue options). Fix the state before buying - a 3V2M NC valve stays NC for life; reversing the base gasket does not convert it, so order NO valves if outlets must pass air at rest.
Flow sizing runs the other way too: at Cv 0.1 per station the 3V2M family is about density, not volume. A standalone 3V2 (Cv 0.18 at 1/8 in, 0.19 at 1/4 in, vacuum-rated) or 3V3 (Cv 0.62, 1/4 in, vacuum-rated) covers positions that need more air, while 3V1 at 3.0 W DC is the low-power pick for light duties. For double-acting cylinders, move to the AirTAC 4V series.
Confirm before you order
Thirteen 3/2 NC direct-acting valves with spring return, each Cv 0.1 on a PT1/8 port, 0-0.8 MPa pressure range, -20 to 70 C media temperature, AC220V coils at 7 VA, IP65 to DIN 40050, flying-lead entry, centralised exhaust and a manual override per station. Air must be filtered to 40 um or finer; lubrication is not required.
The machined base in the 3V2MNCAI-13F has thirteen positions and cannot be extended; order a larger assembly such as the 3V2MNCAI-14F if the machine grows. Within a base, valve types mix freely, so NC and NO valves can share the same supply and wiring.
