Airtac 3V2M Solenoid Valve 3V2MNOBI-2F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOBI-2F 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 3V2MNOBI-2F
The 3V2MNOBI-2F pairs two 3V2M normally open valve bodies with a dedicated 2-station base, ordered and installed as one assembly. Each valve is a direct-acting, coaxial poppet 3/2 unit with spring return and Cv 0.1: air passes from supply to outlet while the AC220V coil is off, and the outlet vents to exhaust the moment it is energised. This inverted logic suits circuits where the idle condition is airflow on.
Electrical entry is a flying lead, so each coil connects through a pre-wired lead-out instead of a DIN socket - handy in tight cabinets. Both stations share one supply and one wiring route tapped from the base, so a misbehaving circuit is located by its position on the manifold rather than by tracing separate harnesses.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNOBI-2F
| 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. |
| DC24V | Coil voltage. A = AC220V, B = DC24V, C = AC110V, E = AC24V, F = DC12V. |
| I | Electrical entry: I = flying lead, otherwise a DIN plug. |
| 2F | 2 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 3V2MNOBI-2F Is Used
Spring-return clamps on a rotary indexing table
Both NO valves feed clamp cylinders whose springs do the gripping; energising a coil vents that line and releases the part for unloading, while the shared base keeps both clamp circuits on a single wiring run.
Intermittent blow-off on a bottle rinser
One normally open station holds the air knife running between cycles; the PLC energises the coil to cut the jet, and the second station serves a second nozzle from the same base supply.
Pilot stage on a diaphragm process valve
The NO outlet keeps pilot pressure on a diaphragm valve through a control-power loss; energising the 3V2M vents the pilot so the process valve returns to its rest position.
Is the Airtac 3V2M Solenoid Valve 3V2MNOBI-2F the Right Part?
Pick 3V2M when station density on one base matters more than per-valve flow: Cv 0.1 per valve, since air crosses the base. If one of the two stations needs more, fit an individual 3V2 (Cv 0.18 at 1/8 in, 0.19 at 1/4 in, vacuum-rated) or a 3V3 (Cv 0.62 at 1/4 in); 3V1 saves power at 3.0 W DC for light duty. Match five points before ordering: initial state NO (this code - NC cannot be converted later, no gasket flip or retrofit changes it), voltage AC220V, entry flying lead, 2 stations, centralised exhaust, plus PT thread as standard (G and NPT are order options). Double-acting cylinders need 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 Blank any unused station on the base before pressurising.
- check Wiring by qualified personnel, per AirTAC documentation.
Airtac 3V2M Solenoid Valve 3V2MNOBI-2F FAQ
Two-station 3/2 normally open assembly on a 3V2M base with PT1/8 ports and centralised exhaust. Cv 0.1 per valve, operating pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, AC coil power 7 VA (DC versions 7.0 W), protection IP65 (DIN 40050). Air must be filtered to 40 um or finer; lubrication is not required. Each valve has a manual override.
NO is right when the outlet should pass air until the signal arrives - idle-blow circuits, fail-vent safety logic, or clamps that release on command. The state is fixed by the valve you order: the base gasket cannot be flipped and no wiring change converts NO to NC, so confirm the state before purchase.
