Airtac 3V2M Solenoid Valve 3V2MNOAI
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOAI 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 3V2MNOAI
The 3V2MNOAI is the normally open, AC220V valve body of the 3V2M manifold family with flying lead entry: instead of a DIN socket you get a pre-wired lead-out, handy where the coil sits in a cramped cabinet or where a wiring loom is prefabricated. Left unpowered, supply and outlet stay connected; energising the single solenoid vents the outlet through the third port. A spring returns the coaxial shut-off poppet, the valve is direct-acting, and it flows at Cv 0.1 with IP65 protection.
This body seats onto a dedicated 3V2M base (ordered separately), where several valves share one air feed and one wiring harness - a layout that makes a fault easy to isolate station by station. A manual override helps during installation. Remember the initial state is built in and cannot be converted later; flipping the base gasket does not turn this NO valve into NC.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNOAI
| 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. |
| NO | Normally open: air passes 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 3V2MNOAI Is Used
Sorting conveyor diverter gate
Feeding a spring-return diverter cylinder beside a parcel belt, this NO body keeps the gate in its default lane whenever control power drops, and wired leads suit a cabinet already full of plugged I/O.
Fastener bowl feed gate
On a bolt-feeding station, the normally open valve holds the air shutoff to the vibratory gate open until the PLC energises the coil, so parts keep flowing through a control fault.
Spray booth damper pilot stage
Used as the pilot for a lab or paint-booth air damper actuator, the flying lead reaches coils tucked behind ductwork where a DIN plug will not fit.
Is the Airtac 3V2M Solenoid Valve 3V2MNOAI the Right Part?
Choose this body when you want normally open behaviour, 220 V AC switching and hard-wired leads. Match five points before ordering: state (NO, fixed for life - no field conversion exists), voltage (AC220V, 7 VA coil), entry (flying lead; the same code without I gives a DIN plug), base station count and exhaust (centralised, or D for independent) plus thread (PT standard, G or NPT to order). On flow, 3V2M is the density pick at Cv 0.1; step up to a single 3V2 (Cv 0.18 at 1/8 in, 0.19 at 1/4 in, vacuum-rated) or a 3V3 (Cv 0.62, 1/4 in, vacuum-rated) if one circuit needs more air, or down to the 3V1 at 3.0 W DC for light duty. A double-acting cylinder belongs on the AirTAC 4V series.
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 3V2MNOAI FAQ
Cv 0.1 flow coefficient, operating pressure 0-0.8 MPa (0-114 psi), temperature range -20 to 70 C, AC coil power 7 VA, protection class IP65 (DIN 40050). The medium is air filtered to 40 um or finer and needs no lubrication. Port is PT1/8, with G and NPT available as order options.
A pre-wired lead-out avoids fitting and removing a plug on coils buried behind other hardware, so it suits sealed cabinets and loom-built machines. As a 3/2 valve it feeds or vents one outlet - right for single-acting spring-return cylinders, blow-off nozzles, clamps and pilot stages. It will not run a double-acting cylinder (that takes a 5-port AirTAC 4V valve) and the NO state cannot be changed after purchase.
