Airtac 3V2M Solenoid Valve 3V2MNOB-14F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOB-14F 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-14F
3V2MNOB-14F gathers fourteen 3/2 normally open valves, each DC24V with DIN plug entry, onto one PT1/8 base that feeds all stations from a single supply and vents them all through one centralised exhaust port. Fewer pipes to the machine, fewer connectors at the panel, and one exhaust point that makes a leaking station easy to hear and isolate.
Each body is direct acting, spring return, coaxial shut-off, Cv 0.1, operating from 0-0.8 MPa at -20 to 70 C on air filtered to 40 um or finer. The normally open state means every outlet feeds air until its coil is energised. Fourteen DC24V coils at 7.0 W reach 98 W, roughly 4.1 A at 24 V, when the whole bank switches at once.

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-14F Is Used
Mixing skid pilot bank
A chemical dosing skid using fourteen 3/2 stations as pilot valves for larger process valves, all trimmed and commissioned through the manual override fitted to each body.
Air-knife drying row
A can-drying conveyor with fourteen blow-off jets, one per station of the bank; the centralised exhaust port keeps the machine frame free of scattered vent lines.
Riveting press hold-downs
An aerospace panel riveting line where fourteen spring-return hold-down cylinders must remain clamped if 24 V control power drops - a duty the normally open state provides by default.
Is the Airtac 3V2M Solenoid Valve 3V2MNOB-14F the Right Part?
Specify five things: the normally open state, DC24V coil, DIN plug electrical entry, fourteen stations, and centralised exhaust; PT is the standard thread, with G or NPT to order. The initial state is built in at manufacture and cannot be swapped afterwards by flipping a gasket or by any other method.
At Cv 0.1 per station this bank trades flow for density. Move a hungry circuit to a separate 3V2 body (Cv 0.18 at 1/8", 0.19 at 1/4", vacuum rated) or a 3V3 (Cv 0.62, 1/4", vacuum rated), or pick 3V1 for light duty at 3.0 W DC. It drives single-acting loads only; double-acting cylinders require 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 3V2MNOB-14F FAQ
Fourteen 3/2 normally open stations, 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 (98 W, roughly 4.1 A at 24 V, all energised), IP65 (DIN 40050), PT1/8 ports, air filtered to 40 um or finer.
Budget for the worst case, not the average: fourteen coils at 7.0 W draw 98 W, close to 4.1 A at 24 V if the whole bank energises together. A supply sized for only a few stations will drop out when a machine cycle switches all fourteen at once.
