Airtac 3V2M Solenoid Valve 3V2MNCB-1F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCB-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 3V2MNCB-1F
This code is a complete single-station assembly: one NC 3/2 valve body seated on its own 3V2M base, giving the manifold-style supply and wiring in a one-position footprint. The valve is direct-acting with a coaxial poppet and spring return, and its DC24V coil terminates in a DIN plug that snaps onto the base socket.
Starting with one station is a common way to build up a machine gradually - the base lets you expand the assembly later without redesigning the supply or wiring. The station still carries full 3V2M figures: Cv 0.1 flow coefficient, 0-0.8 MPa, and a 7.0 W coil, which is only about 0.3 A at 24 V, trivial for almost any panel supply.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNCB-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. |
| DC24V | Coil voltage. A = AC220V, B = DC24V, C = AC110V, E = AC24V, F = DC12V. |

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-1F Is Used
Screen-printing head cleaning
A single NC jet blows the screen clean between print cycles on a flatbed printer, staying shut - and vented - whenever the machine idles.
Welding-jig clamp
One pneumatic clamp on a weld jig is held closed only while the coil is energised, so a supply fault drops the clamp open for part removal.
Bench-top test rig
A small leak or pressure-decay rig uses the station to admit air to the part under test, with the exhaust port giving a defined vent path.
Is the Airtac 3V2M Solenoid Valve 3V2MNCB-1F the Right Part?
As a normally closed unit, this assembly keeps its outlet vented until the coil is energised, which suits guarding, clamps and blow duties that must default to off. The state cannot be swapped later - NC stays NC for life on 3V2M, and re-fitting or flipping the base gasket does not convert it. If the circuit later needs more flow than Cv 0.1, move to 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); for the smallest power draw, 3V1 runs at 3.0 W DC.
Order against five points: NC state, DC24V coil, DIN plug entry, one station with centralised exhaust, and thread (PT is standard; G and NPT can be ordered). For a double-acting cylinder, use the AirTAC 4V series - a 3/2 valve cannot reverse it.
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 3V2MNCB-1F FAQ
One NC 3/2 valve on a dedicated base, PT1/8 port, Cv 0.1 flow coefficient, 0-0.8 MPa operating pressure, -20 to 70 C temperature, DC24V coil at 7.0 W, IP65 (DIN 40050) protection, direct-acting spring-return construction. Air must be filtered to 40 um or finer; lubrication is not required.
Each station has three ports (supply, outlet, exhaust) and two states, so it either feeds or vents one outlet. That drives single-acting spring-return cylinders, air blow jets, clamping and pilot lines - but never a double-acting cylinder, which needs both a pressure and an exhaust path and therefore a 5-port valve such as the AirTAC 4V series.
