Airtac 3V2M Solenoid Valve 3V2MNCEI
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCEI 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 3V2MNCEI
3V2MNCEI is the 3V2M valve body on its own: a 3-port 2-position, normally closed, direct-acting poppet valve with an AC24V coil and a pre-wired flying lead in place of a DIN socket. In the rest position the outlet is vented; energise the coil and the valve feeds the outlet, then the spring returns it to closed when power drops. The lead-out wire makes it easy to land the valve straight into a terminal strip inside a crowded cabinet.
The body mounts on the dedicated 3V2M base, where several valves can share one air supply and one wiring run and be mixed and expanded freely. A manual override helps during installation and commissioning. Flow coefficient is Cv 0.1, coil power is 7 VA, and the construction is rated IP65 (DIN 40050).

Model Code: Airtac 3V2M Solenoid Valve 3V2MNCEI
| 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. |
| AC24V | Coil voltage. A = AC220V, B = DC24V, C = AC110V, E = AC24V, F = DC12V. |
| I | 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 3V2MNCEI Is Used
Control cabinet retrofits
The flying lead lands directly on terminal strips, so replacing an old AC24V valve in a machine's electrical cabinet needs no matching DIN connector.
Pick-and-place grippers
A single-acting gripper on a robot end-of-arm tool opens or closes on one NC valve, spring-returning safely when the coil drops out.
CNC chip-blow nozzles
A normally closed valve keeps the blow-off nozzle silent between cycles and fires an air pulse only when the AC24V coil is energised.
Is the Airtac 3V2M Solenoid Valve 3V2MNCEI the Right Part?
At Cv 0.1, the 3V2M trades some per-station flow for manifold density, since the flow path runs through the base. A station that needs more flow should carry an individual 3V2 valve instead - Cv 0.18 at 1/8 inch and 0.19 at 1/4 inch, and vacuum-rated, which the 3V2M is not - while 3V3 gives the top flow of the range at Cv 0.62 on 1/4 inch. Where the duty is light and power matters, 3V1 needs only 3.0 W on DC. A 3/2 valve handles single-acting cylinders, blow, clamping and pilot duty; double-acting cylinders require a 5-port 4V valve.
Confirm five points before you buy: initial state - NC here, and it cannot be changed to NO afterwards; coil voltage AC24V; electrical entry - the I suffix means flying lead, not a DIN plug; the 3V2M base and station count you will mount it on; and the exhaust style of that base. PT is the standard thread on this family, with G and NPT available to order.
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 3V2MNCEI FAQ
Flow coefficient Cv 0.1; operating pressure 0-0.8 MPa (0-114 psi); temperature range -20 to 70 C; AC coil power 7 VA; protection IP65 (DIN 40050); port PT1/8; medium air filtered to 40 um or finer, no lubrication needed; direct-acting with spring return and a manual override.
It switches one outlet between supply and exhaust, so it suits single-acting spring-return cylinders, on/off air blow, clamping and pilot duty. It cannot drive a double-acting cylinder - that needs two outlet ports and a 5-port AirTAC 4V valve. And being 3V2M, it carries no vacuum rating.
