Airtac 3V2M Solenoid Valve 3V2MNCFI-19F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCFI-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 3V2MNCFI-19F
Nineteen switching points in a single manifold row is what the 3V2MNCFI-19F is built for. Every station is a normally closed, direct-acting 3/2 poppet valve with spring return, fitted with a DC12V coil of 7.0 W on flying leads. The bodies share one supply gallery and one wiring harness through the 3V2M base, which is why commissioning a 19-station machine goes faster than chasing nineteen individual body-mounted valves.
That density has a price in flow: because the air path runs through the base, each station is Cv 0.1, below the individually-ported 3V2 at Cv 0.18. For grippers, pilot lines and small clamps that is ample; for a fast-cycling large bore, plan a mixed build instead. IP65 coil protection, a manual override on each body and PT1/8 ports as standard round out the package, with the whole bank venting through one centralised exhaust path.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNCFI-19F
| 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. |
| 19F | 19 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-19F Is Used
Electronics test fixture
Nineteen clamping and purge ports on a PCB or module test fixture are switched station by station, with the manifold keeping the fixture's air drop and control harness down to one of each.
Automated sample handling
Each spring-return actuator position in a laboratory sample handler gets its own NC station, so a vial is clamped only while the sequencer holds that output energised.
Process skid pilot duty
Pilot and positioner signals on a water-treatment skid are switched from one manifold row; at Cv 0.1 the stations are sized for pilot lines rather than large power cylinders.
Is the Airtac 3V2M Solenoid Valve 3V2MNCFI-19F the Right Part?
Work through the five matching points: normally closed initial state, DC12V voltage, flying-lead entry, 19 stations, centralised exhaust - and PT thread as shipped standard, with G or NPT as catalogue options to order. Bear in mind that NC and NO cannot be interchanged after purchase; the base gasket on 3V2M is dedicated and reversing it changes nothing.
If a station turns out to need more passage than Cv 0.1 allows, step that position up: a single 3V2 gives Cv 0.18 at 1/8 or 0.19 at 1/4 and carries a vacuum rating, 3V3 offers Cv 0.62 at 1/4 for the highest flow in the 3V family, and 3V1 draws only 3.0 W on DC for modest duties. A double-acting cylinder is outside what any 3-port valve can drive - specify the AirTAC 4V 5-port series for that.
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-19F FAQ
Per station: 3/2 direct-acting poppet function, flow coefficient Cv 0.1, pressure range 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, DC12V coil at 7.0 W, IP65 (DIN 40050) protection, PT1/8 ports. The medium is air filtered to 40 um or finer and the valve runs dry - no lubricator needed.
Decide from the machine logic: normally closed passes no air at the outlet until energised, normally open does the opposite. Once ordered the state cannot be changed in the field - flipping or reversing the dedicated base gasket does not convert NC to NO on 3V2M. If any single station needs a larger bore or vacuum service later, that position can be re-planned around an individual 3V2 or 3V3 instead.
