Airtac 3V2M Solenoid Valve 3V2MNOB-5F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOB-5F 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 3V2MNOB-5F
Five switching points from one manifold: the 3V2MNOB-5F mounts five normally open 3/2 valves on a dedicated 3V2M base for a shared supply and a shared wiring run. Direct-acting, spring-return and coaxial poppet construction means each station feeds its outlet while unpowered and vents the moment its DC24V coil pulls in.
Run the power budget before you wire: 7.0 W per station is about 35 W, close to 1.5 A at 24 V, with all five energised - size the supply for that worst case. Centralised exhaust takes all five vents through one common port and one silencer. Each valve keeps a manual override for commissioning, every body is rated IP65 (DIN 40050), and flow per station is Cv 0.1.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNOB-5F
| 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. |
| — | Electrical entry: I = flying lead, otherwise a DIN plug. |
| 5F | 5 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 3V2MNOB-5F Is Used
Tool-change clamps on a machining centre
Five single-acting clamps release in sequence, each governed by one NO station on the shared manifold.
Trailer brake interlock venting
Centralised exhaust bleeds five interlock lines through a single silenced port when coils de-energise.
Fill-head shut-off on a filling machine
Five normally open fill nozzles stay live until each DC24V coil closes its station between fills.
Is the Airtac 3V2M Solenoid Valve 3V2MNOB-5F the Right Part?
Because every path crosses the base, each of the five stations flows at Cv 0.1 - a trade the 3V2M family makes for density. A single station that must move more air deserves its own 3V2 valve (Cv 0.18 at 1/8 in, 0.19 at 1/4 in, vacuum-rated); the 3V3 tops the range at Cv 0.62 on 1/4 in, and 3V1 covers light loads at 3.0 W DC. Specify all of: initial state, coil voltage, electrical entry, station count, exhaust type, and thread (PT as standard, G or NPT to order). Normally open cannot become normally closed after purchase, and no gasket flip changes it. A double-acting cylinder calls for a 5-port valve from the AirTAC 4V range.
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 3V2MNOB-5F FAQ
Per station: Cv 0.1, PT1/8 port, DC24V coil at 7.0 W. Assembly: five normally open stations, 0-0.8 MPa (0-114 psi), -20 to 70 C, IP65 (DIN 40050), centralised exhaust through one common port.
No. The catalogue states the 3V2M uses a dedicated base gasket, and reversing it does not convert NC to NO - the state is set inside the valve at manufacture. If any station must be closed when idle, order that valve as NC. And each 3/2 valve drives single-acting or pilot loads only; a double-acting cylinder needs a 5-port valve from the AirTAC 4V series.
