Airtac 3V2M Solenoid Valve 3V2MNCFI-2F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCFI-2F 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-2F
The 3V2MNCFI-2F is a complete 2-station manifold assembly built from normally closed 3/2 solenoid valves on a shared 3V2M base. Each valve is direct-acting with a spring return and a coaxial shut-off poppet, so the outlet stays vented until the DC12V coil is energised. Power comes in on pre-wired flying leads rather than DIN sockets, which suits low-voltage control cabinets where a moulded lead is simpler than plug wiring.
Flow through the base is Cv 0.1 per valve, and every valve in this kit is fitted with a manual override for commissioning without power. One shared supply and one shared wiring point serve both stations, so a fault on either circuit is traced at a single location. The normally closed state is fixed at the factory and cannot be converted afterwards - order NO instead if you need air to pass until energised.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNCFI-2F
| 3V2M | Body — sets the flow, the coil power and whether vacuum is rated. |
|---|---|
| 1/8 in | Port size. M5, 06 = 1/8 in, 08 = 1/4 in, 10 = 3/8 in. |
| NC | Normally closed: no air at the outlet until the coil is energised. |
| DC12V | Coil voltage. A = AC220V, B = DC24V, C = AC110V, E = AC24V, F = DC12V. |
| I | Electrical entry: I = flying lead, otherwise a DIN plug. |
| 2F | 2 stations in one assembly, centralised exhaust. |
| PT | Port thread. PT ships from stock; G and NPT are available to order. |
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-2F Is Used
Battery-powered gate clamps
Two 12V solenoid circuits on flying leads release spring-return clamping cylinders on a mobile fixture cart, drawing about 14 W with both stations energised.
Pick-and-place blow-off pair
Two NC valves on one manifold give independent on/off air jets for part ejection at a pick point, all fed from a single 12 V supply.
Bench-top test rig sequencing
A compact 2-station base runs two single-acting actuators from one 12 V bench supply, with centralised exhaust keeping the rig tidy.
Is the Airtac 3V2M Solenoid Valve 3V2MNCFI-2F the Right Part?
Match five points before ordering: initial state (NC here), coil voltage (DC12V), electrical entry (flying lead), station count (2) and exhaust type (centralised, vented through a shared port), plus thread - PT is the standard on this family, with G and NPT available as order options. NC versus NO is decided at purchase and cannot be swapped in the field by any means.
At Cv 0.1 this manifold trades flow for density: if a single station needs more air, use an individual 3V2 (Cv 0.18 at 1/8 inch) or step up to 3V3 (Cv 0.62, 1/4 inch). Both are vacuum-rated, which the 3V2M is not. For low-power duty, 3V1 draws only 3.0 W on DC. Double-acting cylinders need a 5-port AirTAC 4V valve, not this 3/2 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 3V2MNCFI-2F FAQ
It is a 2-station assembly of NC 3/2 direct-acting solenoid valves with spring return and coaxial shut-off construction. Flow coefficient Cv 0.1, operating pressure 0-0.8 MPa, temperature -20 to 70 C, DC12V coils at 7.0 W each (14 W total if both are energised), IP65 protection, PT1/8 ports, flying-lead entry and centralised exhaust. Air must be filtered to 40 um or finer; lubrication is not required.
No. A 3/2 valve has three ports (supply, outlet, exhaust) and two states, so it either feeds or vents one outlet. That suits single-acting spring-return cylinders, blow-off and clamping. A double-acting cylinder needs two outlets in both states, which is the job of a 5-port AirTAC 4V valve.
