Airtac 3V2M Solenoid Valve 3V2MNOF-16F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOF-16F 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-16F
The 3V2MNOF-16F is a complete 16-station manifold assembly built around AirTAC 3V2M normally open (NO) poppet valves running on DC12V coils. Each 3/2 valve is direct-acting with spring return and a coaxial shut-off element, so it either feeds the outlet or vents it. Being normally open, every station passes air while de-energised and shuts off only when its 7.0 W coil is energised - useful wherever the safe condition is air flowing, not blocked.
All sixteen valve bodies sit on one dedicated base, so the assembly draws one shared air supply and one shared wiring loom instead of sixteen separate connections. Manual overrides are fitted to each body for commissioning, and every valve carries an IP65 (DIN 40050) coil rating. Worth budgeting up front: with all sixteen DC12V coils energised the assembly draws about 112 W, roughly 9.3 A at 12 V - size the 12 V supply for that worst case, not for one station.

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-16F Is Used
Power-failure retraction on a printing press guard clamp
Because each NO valve opens its supply path while de-energised, a mains loss leaves single-acting guard clamps fed rather than stranded; energising the DC12V coil vents the clamp so the spring retracts it on command.
Chip-clearing air jets on a CNC saw station
On a 16-position saw line the blow-off nozzles need air by default; each normally open 3/2 station delivers it continuously and only cuts a jet when the controller energises that station's coil.
Sixteen-point pilot signal bank on a textile machine
One shared supply and one shared wiring loom feed all 16 pilot-duty stations through the common base, so a technician can isolate a faulty station on the block instead of tracing sixteen separate valve installs.
Is the Airtac 3V2M Solenoid Valve 3V2MNOF-16F the Right Part?
Choose this assembly when you need high valve density in one block and your circuit wants air to flow at rest. The flow path runs through the base, so each station is Cv 0.1; if any station must pass more air, mount an individual 3V2 instead (Cv 0.18 at 1/8 in, 0.19 at 1/4 in, vacuum-rated) or a 3V3 (Cv 0.62, 1/4 in, vacuum-rated). For low-duty points where coil heat matters more than flow, the 3V1 at 3.0 W DC is the lighter option. If you actually need to drive a double-acting cylinder, that takes a 5-port AirTAC 4V valve, not a 3/2.
Match five points before ordering: initial state (NO here), coil voltage (DC12V), electrical entry (DIN plug on this code; a flying-lead I version exists), station count (16) and exhaust type (centralised on this code; independent D versions exist). Thread is PT as standard, with G and NPT available to order. Critically, the NO state is fixed at order time - the dedicated base gasket cannot be flipped to convert NO to NC, so a normally closed circuit needs a different SKU.
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-16F FAQ
Each of the 16 stations is a 3/2 direct-acting, spring-return, normally open valve with Cv 0.1, operating pressure 0-0.8 MPa (0-114 psi), temperature range -20 to 70 C, and a DC12V coil rated 7.0 W (16 coils together draw about 112 W, near 9.3 A at 12 V). Coil protection is IP65 (DIN 40050), air must be filtered to 40 um or finer with no lubrication required, ports are PT1/8 with a centralised exhaust, and a manual override is fitted per valve.
No. The NO initial state is fixed when ordered - the 3V2M uses a dedicated base gasket and reversing or flipping that gasket does not convert the state, so a normally closed circuit must be ordered as a different SKU. Function-wise each 3/2 station has three ports and two states, feeding or venting the outlet, so it suits single-acting spring-return cylinders, blow-off, clamping and pilot duty - but it cannot drive a double-acting cylinder, which needs a 5-port AirTAC 4V valve.
