Airtac 3V2M Solenoid Valve 3V2MNOAI-7F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOAI-7F 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-7F
At seven stations the 3V2MNOAI-7F shows what the 3V2M platform is built for: seven normally open 3/2 valves on one base, sharing a unified supply and a unified wiring loom, each valve driven by a 7 VA AC220V coil on a flying lead. When a station misbehaves, you troubleshoot one valve on the bank instead of seven scattered units.
Each valve shifts with a spring return and a coaxial poppet seal, direct-acting with no pilot air required. In NO duty the outlet passes air until the coil is energised - convenient for circuits that must vent or blow by default. Total energised draw is 49 VA across seven stations; flow stays at Cv 0.1 per valve.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNOAI-7F
| 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. |

| 7F | 7 stations in one assembly, centralised exhaust. |
| 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-7F Is Used
Environmental chamber dampers
In a university materials lab, seven normally open stations open spring-return vent dampers on an environmental chamber whenever supply is live; energising a coil closes that damper for a test cycle.
Solvent store vent stacks
At a coating plant's solvent store, the NO valves keep spring-return vent stack actuators pressurised open by default; energising a station vents and closes its stack under an interlock signal.
Robotic welding fixture clamps
A robotic welding cell clamps seven sheet-metal parts with spring-return cylinders fed by the normally open valves, so clamps engage automatically on air-up and release station by station under robot command.
Is the Airtac 3V2M Solenoid Valve 3V2MNOAI-7F the Right Part?
Confirm the five ordering points - NO initial state, AC220V coils, flying-lead entry, seven stations, centralised exhaust - plus thread: PT is standard on this family, with G and NPT as options to order. The normally open state cannot be converted after purchase; flipping the dedicated base gasket does not change it.
If a circuit needs more than Cv 0.1 per valve, move that circuit to an individual 3V2 (Cv 0.18 at 1/8 inch, 0.19 at 1/4 inch, vacuum-rated) or to 3V3 (Cv 0.62, 1/4 inch, vacuum-rated); 3V1 at 3.0 W DC covers low-power duty. This 3/2 manifold never drives double-acting cylinders - specify the AirTAC 4V series for those.
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 Blank any unused station on the base before pressurising.
- check Wiring by qualified personnel, per AirTAC documentation.
Airtac 3V2M Solenoid Valve 3V2MNOAI-7F FAQ
Per valve: Cv 0.1, operating pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, AC220V coil at 7 VA (49 VA across all seven stations energised), IP65 rating to DIN 40050. Ports are PT1/8, with air filtered to 40 um or finer and no lubrication needed.
Every AC220V coil draws 7 VA, so seven stations energised together pull about 49 VA through the shared flying-lead loom. Size the control transformer for that worst case and land each flying lead per station, so a faulty coil can be isolated without disturbing the rest of the bank.
