Airtac 3V2M Solenoid Valve 3V2MNCA-8F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCA-8F 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 3V2MNCA-8F
3V2MNCA-8F packs eight NC 3/2 stations onto a single 3V2M manifold: AC220V coils, DIN plug entry, PT1/8 ports, one common supply. The valve is direct-acting with spring return and a coaxial poppet seat, so while a station is de-energised its outlet is tied to exhaust and isolated from supply - the safe resting state for clamps and slides. Coil power is 7 VA, giving a 56 VA ceiling when the whole bank runs.
Buyers often mix duties across one block because 3V2M stations combine freely and can be of mixed types; the shared wiring also means a suspect valve is found by swapping positions on the base, not by rewiring the panel.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNCA-8F
| 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. |

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 3V2MNCA-8F Is Used
Blow-off nozzle array
Eight NC stations switching pulsed air knives and nozzles that clear chips on a machining line, all stations venting through the one central exhaust port.
Test rig slide actuation
Eight NC valves switching spring-return slides and part stoppers on a qualification test rig, wired from a single DIN-plug entry on the manifold.
Press feeder grippers
Pilot duty on a high-speed stamping press feeder, where eight NC stations fire grip and release cylinders in fast sequence from one shared supply.
Is the Airtac 3V2M Solenoid Valve 3V2MNCA-8F the Right Part?
An 8-station bank at Cv 0.1 trades per-station flow for panel density; lift any demanding station out onto its own 3V2 (Cv 0.18 at 1/8 inch, Cv 0.19 at 1/4 inch, vacuum-rated) or a 3V3 (Cv 0.62 at 1/4 inch, vacuum-rated) if the circuit needs it. For small duties, 3V1 draws only 3.0 W on DC. Cylinders with two air ports need the AirTAC 4V 5/2 range instead.
Lock down: NC initial state, AC220V, DIN plug, 8 stations, centralised exhaust, PT thread (G and NPT to order). The NC state cannot be changed afterwards - flipping the dedicated base gasket does not convert the valve, so confirm every outlet should be vented while de-energised.
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 3V2MNCA-8F FAQ
Cv 0.1 flow coefficient per station; 0-0.8 MPa (0-114 psi) operating pressure; -20 to 70 C temperature; AC220V coils at 7 VA (DC versions 7.0 W); IP65 to DIN 40050; PT1/8 ports; clean air filtered to 40 um or finer, no lubrication required.
It is not. 3V2M relies on a dedicated base gasket, and the catalogue states reversing or flipping that gasket does not convert NC to NO. With eight identical NC stations, check that every outlet should be vented to exhaust while de-energised before ordering; NO bodies are a separate order code.
