Airtac 3V2M Solenoid Valve 3V2MNCB
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCB 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.
- Valve type3/2-way (3-port, 2-position)

About the Airtac 3V2M Solenoid Valve 3V2MNCB
3V2MNCB is the valve body on its own: an NC 3/2 direct-acting coaxial poppet with spring return, a 7.0 W DC24V coil and a DIN plug connection, ready to seat on a 3V2M base. While de-energised the outlet stays closed and vented; energising the coil feeds the outlet from supply. The body carries IP65 protection and a manual override for commissioning.
Ordering the body separately lets you set the exact state and voltage for every position on the manifold, then pair them with a base of the station count you need (base ordered separately). With the DIN plug, replacing a coil is a pull-and-push job - no rewiring. Flow is Cv 0.1 per valve through the base path.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNCB
| 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. |
| DC24V | Coil voltage. A = AC220V, B = DC24V, C = AC110V, E = AC24V, F = DC12V. |
| — | Electrical entry: I = flying lead, otherwise a DIN plug. |
| 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 3V2MNCB Is Used
24 V control-panel wiring
The 7.0 W DIN-plug coil plugs straight into a cabinet socket, letting several 3V2MNCB bodies sit on one base fed by a single 24 V supply.
Multi-spindle nutrunner fixture
Spring-return clamps around a bolt-tightening station hold the part with one NC-controlled valve per position.
Leak-test bench venting
On a leak-test rig, the NC valve vents the part to atmosphere between cycles so the part is never left pressurised.
Is the Airtac 3V2M Solenoid Valve 3V2MNCB the Right Part?
Five decisions define the order: NC or NO, coil voltage, DIN plug or flying lead, base station count, and exhaust arrangement; thread follows as PT standard or G/NPT to order. NC is built in here and stays NC - no gasket flip or field trick converts it, so order an NO code if the outlet must pass air at rest.
This body is the density pick at Cv 0.1. Where one position needs more flow, fit an individual 3V2 (Cv 0.18 at 1/8", 0.19 at 1/4", vacuum rated) or a 3V3 (Cv 0.62, 1/4", vacuum rated); where draw must be minimal, 3V1 sips 3.0 W on DC. For double-acting cylinder control, switch to the 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 Wiring by qualified personnel, per AirTAC documentation.
Airtac 3V2M Solenoid Valve 3V2MNCB FAQ
3V2MNCB is an NC 3/2 body with Cv 0.1, a DC24V coil of 7.0 W and a DIN plug connection. Operating pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, IP65 to DIN 40050, port PT1/8, manual override fitted. Medium is air filtered to 40 um or finer, and lubrication is not required.
NC means the outlet is closed and vented until the 24 V coil is energised; NO passes air until energised. On 3V2M the state is set by the valve body and its dedicated base gasket at the factory - flipping the gasket does not swap NC to NO. Decide which state each circuit position needs and order that code.
