Airtac 3V2M Solenoid Valve 3V2MNCF-19F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCF-19F 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 3V2MNCF-19F
The 3V2MNCF-19F is a complete 19-station manifold assembly: nineteen 3/2 normally closed valve bodies in the F (DC12V) coil version with DIN plug entry, factory-mounted on a single 3V2M base with a centralised exhaust. Each valve is direct-acting, single solenoid with spring return and a coaxial shut-off poppet that seals tightly. With the coil off, the outlet passes no air; when energised it feeds, and on de-energising the spring vents the line.
Because all nineteen valves share one air supply and one wiring run, commissioning a large 12 V panel is simpler and faults are easier to trace station by station. Mind the power budget before choosing a power supply: each DC coil draws 7.0 W, so a fully energised 19-station assembly pulls about 133 W, roughly 11 A at 12 V. Manual override on every body helps during installation and set-up.

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 3V2MNCF-19F Is Used
Battery-powered utility trucks
Single-acting clamp and blow-off circuits run straight from the 12 V vehicle supply through one shared manifold, with no inverter on board.
Multi-lane tray sealing line
Nineteen stations gate or vent each tray lane from a single 12 V panel, and the centralised exhaust keeps one ducted vent instead of nineteen.
Drilling fixture clamping
Spring-return clamps on a bolt-hole drilling fixture each get their own NC valve, so parts stay clamped whenever coil power is lost.
Is the Airtac 3V2M Solenoid Valve 3V2MNCF-19F the Right Part?
Choose this code when you need many small 3/2 circuits on one 12 V supply and Cv 0.1 per station is enough flow. If any single station needs more, mount an individual 3V2 there (Cv 0.18 at 1/8 in, 0.19 at 1/4 in, and vacuum-rated) or step up to 3V3 (Cv 0.62 at 1/4 in); 3V1 is the light-duty option at 3.0 W DC. Note that 3V2M itself carries no vacuum rating.
Order by five points: NC initial state, DC12V coil, DIN plug entry, 19 stations, centralised exhaust - with PT as the standard thread and G or NPT available to order. The NC state cannot be converted to NO after purchase; flipping the dedicated base gasket does not swap it. If you must drive a double-acting cylinder, that needs the 5-port AirTAC 4V series, not this 3/2 valve.
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 3V2MNCF-19F FAQ
Each of the 19 valves is a 3/2 NC, direct-acting, spring-return poppet valve with a Cv 0.1 flow coefficient, 0-0.8 MPa working pressure, -20 to 70 C media temperature and IP65 (DIN 40050) protection. The DC12V coils draw 7.0 W each (AC coils in the 3V2M family are 7 VA). Ports are PT1/8, air must be filtered to 40 um or finer with no lubrication required, and exhaust is centralised through the base.
No. The initial state is fixed by the valve version you order. The dedicated base gasket cannot be flipped to swap NC for NO, and no field modification converts the state. If the outlet must pass air while the coil is off, order the normally open version (for example 3V2MNOF-19F) from the start.
