The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCC-9F 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.
Nine NC 3/2 poppet valves share one AC110V supply and one wiring run on this 9-station base, with DIN plug entry on every coil. Centralised exhaust means all nine stations vent through a single manifold port, so one silencer handles the whole bank instead of nine separate pipes.
Two engineering facts shape the choice. First, routing the flow path through the base costs flow: Cv 0.1 here against the free-standing 3V2's 0.18, so keep heavy-blow duties off this manifold. Second, the shared exhaust mixes vented air from all stations - useful for compact routing, wrong if one station must be isolated or its venting recovered separately. Each coil takes 7 VA, about 63 VA with all nine energised, and the NC state is fixed at order time.

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. |
| AC110V | Coil voltage. A = AC220V, B = DC24V, C = AC110V, E = AC24V, F = DC12V. |

| 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 conveyor line with nine stop-and-release gates uses one NC valve per gate; energising feeds the stopper cylinder, and the centralised exhaust keeps the whole run's venting on a single duct.
A leak-test bench cycling nine small clamp cylinders assigns one station per fixture; the shared supply and wiring make a failed fixture easy to spot by which coil drops out.
Nine case hold-down clamps on a packaging machine fire in sequence from one AC110V supply; spring return plus NC valves means every clamp opens the moment the line stops.
Confirm the five points: NC initial state (cannot be changed after purchase), AC110V coil, DIN plug entry, nine stations, centralised exhaust; PT is the standard thread, with G and NPT as catalogue options. If a station drives a bigger cylinder or a blow-off that Cv 0.1 cannot feed, put an individual 3V2 (Cv 0.18 at 1/8, 0.19 at 1/4) or a 3V3 (Cv 0.62, 1/4) on that function and keep the 3V2M for the light pilot loads. 3V1 at 3.0 W DC covers small duties at lower power. Double-acting cylinders need the AirTAC 4V 5-port series.
Confirm before you order
3/2 NC valves, Cv 0.1, operating pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, AC110V coil at 7 VA each (about 63 VA for nine), IP65 protection, PT1/8 ports with G and NPT to order.
Centralised exhaust vents all nine stations through one port, which simplifies silencing but mixes station venting; order the -D suffix version if stations need separate exhausts. A 3/2 valve feeds or vents one outlet, so it suits single-acting cylinders only - a double-acting cylinder requires a 5-port valve such as the AirTAC 4V.
