Airtac 3V2M Solenoid Valve 3V2MNOF-18F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOF-18F 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 3V2MNOF-18F
Eighteen normally-open 3/2 valves share one 3V2M base and one wiring run in this assembly. Every station passes air at rest; energising its 7.0 W DC12V coil closes that station's coaxial poppet and dumps the downstream line to the centralised exhaust. The direct-acting construction means no minimum pressure is needed to shift the valve - the solenoid and spring do all the work.
Size the power supply for the worst case: eighteen coils at 7.0 W is 126 W, roughly 10.5 A at 12 V if the whole bank sits energised. With one shared supply port, PT1/8 threading, IP65 DIN plug connections and a manual override on each valve, the 18-station layout suits control panels where wiring channels are scarce.

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 3V2MNOF-18F Is Used
18-spindle machine tool clamping
Normally-open valves hold each single-acting clamp fed from a shared supply; energising the coil vents and releases that spindle, so a control fault drops all clamps open.
Parcel sorter diverter bank
Eighteen diverters on one manifold: air passes to each diverter cylinder at rest, and the PLC energises a station to stop and vent it - one supply, one wiring route.
Analyser sampling manifold
A 3/2 normally-open valve per sample line keeps carrier air flowing by default; each DC12V coil shuts one stream for calibration without starving the other seventeen.
Is the Airtac 3V2M Solenoid Valve 3V2MNOF-18F the Right Part?
Use 3V2M where manifold density beats raw flow: Cv 0.1 per valve is the price of routing the flow through the base. A station that needs more air should take an individual 3V2 (Cv 0.18 at 1/8 in, Cv 0.19 at 1/4 in, vacuum-rated), and the highest-flow 3V option is 3V3 (Cv 0.62, 1/4 in, vacuum-rated); 3V1 at 3.0 W DC is the low-power alternative for small duties. Double-acting cylinders are out of scope for any 3-port valve - specify AirTAC 4V there. Confirm these five choices before ordering: NO state (fixed at purchase, not field-convertible), DC12V, DIN plug, 18 stations, centralised exhaust, and thread - PT is standard, G and NPT are order options.
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 3V2MNOF-18F FAQ
Every DC12V coil is rated 7.0 W, so a fully energised 18-station bank draws about 126 W, near 10.5 A at 12 V. Choose a 12 V supply with headroom above that. Flow per valve is Cv 0.1, pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, protection IP65 (DIN 40050).
Each 3/2 station feeds or vents one line, so it drives single-acting spring-return cylinders, air blow, clamping and pilot stages. It cannot drive a double-acting cylinder - that requires a 5-port valve from the AirTAC 4V series. Note also that NO cannot be changed to NC after purchase.
