Airtac 3V2M Solenoid Valve 3V2MNOC-4F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOC-4F 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 3V2MNOC-4F
The 3V2MNOC-4F mounts four NO valve bodies on one 3V2M base so a four-function sub-system of single-acting cylinders, air jets or pilot signals runs off one PT1/8 supply and one AC110V wiring entry. Each valve is normally open: air flows to the outlet with the coil dead, and energising the 7 VA coil shuts that function. Spring return and coaxial shut-off give a firm seat that does not creep with pressure changes.
Wiring is where the 4-station format pays off: four DIN plugs land on one shared feed instead of four separate valve installations, and IP65 (DIN 40050) coil protection suits demanding cabinet environments. All four stations vent through the centralised exhaust port on the base, and the manual override on each body lets you prove the mechanics before the controller is connected.

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 3V2MNOC-4F Is Used
Carton former glue jets
Four glue nozzles on a tray-forming machine switch on and off in sequence from one 4-station base; the centralised exhaust carries all four vent pulses to a single muffler.
Cobot gripper bank
A collaborative robot end effector holds four single-acting grippers; because the valves are NO, a controller fault keeps the grippers fed and holding rather than dropping the part.
Fermenter automated sampler
A fermentation lab sequences four sample-draw cylinders from one shared supply; DIN plugs on a single AC110V feed replace four separate valve installations in the wet-bench cabinet.
Is the Airtac 3V2M Solenoid Valve 3V2MNOC-4F the Right Part?
Manifold density trades flow for compactness: each 3V2M position is Cv 0.1, so a hungry cylinder may prefer a standalone 3V2 at Cv 0.18 (1/8 inch) or 0.19 (1/4 inch), or a 3V3 at Cv 0.62 (1/4 inch) for the highest flow in the 3V range; the 3V1 at 3.0 W DC is the low-power option for light duties. Four AC110V coils mean up to 28 VA with every station energised, so check the transformer, not just the air. Double-acting cylinders require a 5-port valve from the AirTAC 4V series.
Nothing about the NO state can be changed later: the dedicated 3V2M base gasket does not convert NO to NC when reversed, so order the state deliberately. Specify six items when ordering: NO, AC110V, DIN plug entry, 4 stations, centralised exhaust and thread, where PT is the family standard and G and NPT are order options.
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 3V2MNOC-4F FAQ
Four 3/2 direct-acting stations, Cv 0.1 each, operating pressure 0-0.8 MPa, temperature -20 to 70 C and IP65 (DIN 40050). Coils are AC110V at 7 VA, so 28 VA if all four energise at once. Ports are PT1/8 with G or NPT to order, and the exhaust is centralised through one base port.
NO means each outlet passes air while its coil is de-energised and shuts when energised, useful where a function must stay live through a power cut. It cannot be altered afterwards: the dedicated base gasket does not convert NO to NC when flipped, so order the state you need. For double-acting cylinders use an AirTAC 4V 5/2 valve instead.
