Airtac 3V2M Solenoid Valve 3V2MNOB-11F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOB-11F 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-11F
The 3V2MNOB-11F is a complete eleven-station assembly: eleven 3/2-way normally open valve bodies in DC24V DIN-plug form mounted on one dedicated 3V2M base with PT1/8 ports. A single air feed serves the whole bank, one wiring run covers all eleven coils, and the centralised exhaust collects every station's vent at a common port. Because the valves are NO, each outlet passes air as soon as the supply is on and only vents when its coil is energised.
Every body is direct acting with spring return and coaxial shut-off poppet construction, rated Cv 0.1 per station over 0-0.8 MPa and -20 to 70 C. At 7.0 W per DC24V coil a fully energised eleven-station bank draws about 77 W, near 3.2 A at 24 V, so size the power supply for all stations switching together. Manual override on each body speeds up installation and commissioning.

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-11F Is Used
CNC fixture clamp bank
Eleven spring-return swing clamps on a machining-centre jig, each switched by one station of the bank; the NO state keeps every clamp pressurised through a control-power loss, holding the part until the PLC deliberately vents it.
Parcel sorter pusher array
A distribution-centre sorter with eleven single-acting pusher cylinders diverting cartons lane by lane; one supply, one wiring run and one central exhaust serve the whole row of stations.
Threaded-part ejection bench
On a fastener assembly bench, each station vents to drop the finished part from its nest; eleven stations let one manifold drive the full set of ejection pins and blow-off nozzles.
Is the Airtac 3V2M Solenoid Valve 3V2MNOB-11F the Right Part?
Match five points before ordering: initial state (NO here - it cannot be changed after purchase, and flipping the base gasket does not convert it), coil voltage (DC24V), electrical entry (DIN plug; the -I suffix gives flying leads), station count (11F) and exhaust type (centralised here; -D gives independent exhaust per station). Thread is PT as standard; G and NPT are catalogue options to order.
On flow, the 3V2M buys manifold density, not volume: Cv 0.1 per station. If one circuit needs more, step it to an individual 3V2 (Cv 0.18 at 1/8", 0.19 at 1/4", vacuum rated) or a 3V3 (Cv 0.62, 1/4", vacuum rated); 3V1 is the low-power choice at 3.0 W DC. For a double-acting cylinder use the AirTAC 4V series instead - a 3/2 valve cannot drive one.
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-11F FAQ
It is an 11-station 3/2 normally open assembly: Cv 0.1 per station, operating pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, DC24V coils at 7.0 W each (77 W total energised), IP65 to DIN 40050, PT1/8 ports, medium air filtered to 40 um or finer, with no lubrication required.
No. The initial state is set at manufacture by the dedicated base gasket, and the catalogue states that reversing that gasket does not convert NC to NO or the reverse. Order NO only for circuits that must pass air while de-energised; order NC valves instead if a station must stay vented until switched.
