Airtac 3V2M Solenoid Valve 3V2MNCAI-2F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCAI-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 3V2MNCAI-2F
Two matched normally closed 3/2 valves on one compact block - that is the 3V2MNCAI-2F. Each AC220V coil arrives pre-wired on a flying lead, and each station vents its outlet until energised, so both circuits are safe at rest. The direct-acting, spring-return coaxial poppet design seals well at Cv 0.1 and works from 0 to 0.8 MPa.
The 2F base feeds both valves from one supply and vents them through a single centralised exhaust port, which keeps the piping footprint small on crowded machines. One wiring run serves both flying leads. Manual overrides are fitted for commissioning. Remember the initial state is built in: the dedicated base gasket cannot be flipped to turn NC into NO, so order the state correctly.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNCAI-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. |
| AC220V | 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 3V2MNCAI-2F Is Used
Indexing table stops
Two spring-return stop cylinders on a rotary indexing table, sequenced by their manifold stations and retracted by the spring whenever power is off.
Chip-clearing blow-off pair
Two air nozzles on a drilling station clearing chips between cycles, blowing only while the AC220V coils are energised.
Guard latch circuits
Pneumatic latches on a machine hood, held by the manifold stations during operation and vented to the common exhaust the moment the coils drop.
Is the Airtac 3V2M Solenoid Valve 3V2MNCAI-2F the Right Part?
Start with the flow question: Cv 0.1 per station is the price of manifold density on 3V2M. If either of your two circuits needs more, replace it with an individually ported 3V2 (Cv 0.18 at 1/8 in, 0.19 at 1/4 in, vacuum rated) or 3V3 (Cv 0.62, 1/4 in); for light duties 3V1 saves power at 3.0 W DC. Then confirm the five points: NC state, AC220V coil at 7 VA, flying-lead entry, 2-station count, and centralised exhaust with PT thread (G and NPT on request). NC/NO cannot be changed after purchase.
These valves drive single-acting cylinders and pilot ports only. If your actuator is double-acting, you need the 5-port AirTAC 4V series instead.
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 3V2MNCAI-2F FAQ
Two 3/2 NC stations, each with Cv 0.1 flow coefficient, operating pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, coil power 7 VA on AC and 7.0 W on DC, and IP65 (DIN 40050) protection. PT1/8 ports on a PT-threaded base; G and NPT threads to order.
The 2F base gives both valves one shared air supply and one shared wiring run, so fault-finding is faster and piping is cleaner - both stations vent through a single centralised exhaust. Expansion is free: add stations to the same 3V2M bank as the machine grows.
