Airtac 3V2M Solenoid Valve 3V2MNCAI-1F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCAI-1F 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-1F
The 3V2MNCAI-1F is a complete single-station assembly: one normally closed 3/2 valve body with an AC220V solenoid and flying-lead entry, factory mounted on a 1F base with PT threads. Until the coil is energised the outlet stays vented to exhaust; energise it and the valve feeds the outlet from the supply, and the spring returns it to vent when power drops. The construction is direct acting with a coaxial shut-off poppet, giving tight sealing at Cv 0.1.
The 1F base is the starting block of the 3V2M manifold system: one shared air supply, one shared wiring run, and free expansion as your circuit grows. Wiring is by pre-fitted lead-out wire rather than a DIN socket, which speeds panel routing. A manual override is fitted for set-up and commissioning. Note that the NC state cannot be converted to NO after purchase - order the initial state you need.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNCAI-1F
| 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. |
| 1F | 1 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-1F Is Used
Bench test rig circuits
Switching air to a single test fixture on an R&D bench, wired by lead-out wire, with the option to grow the manifold station by station later.
Pilot duty for process valves
Driving the pilot port of a larger process valve in a water treatment skid, where each 3V2M station switches one pilot line off a shared supply.
Clamping on an assembly jig
One spring-return clamp cylinder on an electronics fixture jig, released automatically whenever the AC220V coil is de-energised.
Is the Airtac 3V2M Solenoid Valve 3V2MNCAI-1F the Right Part?
Match five points before ordering: initial state (NC here - the outlet is vented until energised), coil voltage (AC220V at 7 VA), electrical entry (flying lead instead of a DIN plug), station count (1F, expandable later) and exhaust type (centralised on this base, PT thread; G and NPT are order items). The NC/NO state is fixed at manufacture - the dedicated base gasket cannot be flipped or otherwise converted, so buy the state you need.
Flow through a 3V2M base is Cv 0.1. If a circuit needs more, an individually ported 3V2 gives Cv 0.18 at 1/8 in or 0.19 at 1/4 in and is vacuum rated; 3V3 reaches Cv 0.62 at 1/4 in for the highest flow in the 3V range. Where the duty is small, 3V1 is the low-power pick at 3.0 W DC. This valve drives single-acting cylinders and pilot ports only - for double-acting cylinders use the 5-port AirTAC 4V 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 3V2MNCAI-1F FAQ
It is a 3/2 normally closed assembly with a Cv 0.1 flow coefficient, operating pressure 0-0.8 MPa (0-114 psi), temperature range -20 to 70 C, coil power of 7 VA on AC and 7.0 W on DC, and IP65 (DIN 40050) protection. Ports are PT1/8 on a PT base; G and NPT threads are available to order.
No. The 3V2M uses a dedicated base gasket, and reversing or flipping that gasket does not change the initial state - the catalogue states this explicitly. Order NC or NO correctly at purchase: NC keeps the outlet vented until energised, while the NO version (3V2MNOAI-1F) passes air until energised.
