Airtac 3V2M Solenoid Valve 3V2MNCFI-3F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCFI-3F 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 3V2MNCFI-3F
The 3V2MNCFI-3F arrives as a working unit: three normally closed 3/2 valve bodies clipped onto a 3-station 3V2M base, wired for DC12V and exhausting through one shared central port. Each valve is direct-acting with a spring return and a coaxial shut-off poppet, so it holds a tight seal at the outlet until its coil is energised. Because the valves share the base, one PT1/8 air supply feeds all three stations and one wiring run covers all three coils.
The FI in the code means each coil is terminated in a pre-wired flying lead rather than a DIN socket, which suits panels where connectors are awkward or leads route straight to a terminal strip. At 12 V DC each station draws 7.0 W, so all three energised together need 21 W from your supply. Manual overrides are fitted for commissioning, and the bodies carry an IP65 (DIN 40050) rating.

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 3V2MNCFI-3F Is Used
Workholding clamp bank on a small machining fixture
Three NC valves each vent their spring-return clamp cylinder when de-energised and clamp on command, all fed from one base supply - a compact way to sequence clamp, position and eject on a fixture plate.
Sample purge and blow-off station in a lab automation cell
DC12V logic drives the flying-lead coils straight from low-voltage control electronics: one valve blows debris off a sensor head, another vents a purge line, the third gates air to a pick point.
Multi-cavity ejection on a small packaging tray former
Each station's NC valve feeds a single-acting ejector pin for one tray cavity, so a stuck cavity can be pulsed on its own without touching the other two stations on the shared base.
Is the Airtac 3V2M Solenoid Valve 3V2MNCFI-3F the Right Part?
Pick this assembly when you need three isolated 3/2 functions on one compact manifold and your control side runs 12 V DC with direct lead wiring. Check the five match points before ordering: NC state, DC12V coil, flying-lead entry, 3 stations, and centralised exhaust on a PT-threaded base (G and NPT are order options, not the standard). NC and NO are fixed at order time on 3V2M - the base gasket cannot be flipped to change it, so the state you order is the state you live with.
Flow is Cv 0.1 per station, because the air path runs through the base rather than a ported body. If one station needs more, use an individual 3V2 (Cv 0.18 at 1/8 in, vacuum-rated) or a 3V3 (Cv 0.62, 1/4 in, vacuum-rated); if the duty is light and you want lower power draw, 3V1 takes 3.0 W on DC. For any double-acting cylinder, move to the 5-port AirTAC 4V series - no 3/2 valve will do that job.
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 3V2MNCFI-3F FAQ
It is a 3-station 3V2M assembly with three 3/2 normally closed direct-acting valves, DC12V coils at 7.0 W each, flying-lead entry, Cv 0.1 flow coefficient per valve, operating pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, IP65 (DIN 40050) protection, air filtered to 40 um with no lubrication required, manual override fitted, centralised exhaust and PT ports.
NC means the outlet stays vented and no air passes until the 12 V coil is energised - the safe default for clamping and blow duty that must shut off on power loss. On 3V2M the NC/NO state is set by the valve body and dedicated base gasket at the factory; reversing the gasket does not convert NC to NO. Confirm the state before ordering, because it cannot be converted in the field.
