Airtac 3V2M Solenoid Valve 3V2MNOCI-18F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOCI-18F 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 3V2MNOCI-18F
The 3V2MNOCI-18F mounts eighteen 3/2 NC poppet valves on one manifold block with a single centralised exhaust. The coaxial shut-off design seals reliably, but because every flow path passes through the base, each station is Cv 0.1 - the honest price of packing eighteen valves into one PT1/8 gallery. Coils are AC220V at 7 VA with flying-lead entry for direct wiring.
All eighteen coils together draw about 126 VA when energised, worth checking against your transformer headroom. Shared supply and wiring also mean one manual override per valve is enough to jog any station during commissioning. NC holds every outlet vented until commanded, and the state is locked in at purchase - no conversion afterwards.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNOCI-18F
| 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. |
| NO | Normally open: air passes until the coil is energised. |
| AC110V | Coil voltage. A = AC220V, B = DC24V, C = AC110V, E = AC24V, F = DC12V. |
| I | Electrical entry: I = flying lead, otherwise a DIN plug. |
| 18F | 18 stations in one assembly, centralised exhaust. |
| 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 3V2MNOCI-18F Is Used
Automotive leak-test clamps
Eighteen clamp stations on a test bench close over castings during pressure decay checks, each venting automatically the instant its NC coil drops.
Parcel sorter lane gates
Sorting lanes use rows of small single-acting diverters; one manifold supplies and exhausts the whole row, keeping cabinet wiring to a single trunk.
Printing press impression rollers
Short-stroke impression cylinders on a press engage only while energised, which matches the fail-vented behaviour of these NC 3/2 stations.
Is the Airtac 3V2M Solenoid Valve 3V2MNOCI-18F the Right Part?
Match five parameters to your project: initial state (NC), coil voltage, electrical entry, station count and exhaust routing, plus thread - PT standard, G or NPT on order. On sizing: 3V2M buys density at the cost of flow, so step a high-flow station to an individual 3V2 (Cv 0.18 at 1/8 in, 0.19 at 1/4 in, vacuum-rated) or 3V3 (Cv 0.62 at 1/4 in, vacuum-rated), or pick 3V1 at 3.0 W DC when power is tight. NC/NO is fixed at purchase and cannot be reversed later, and double-acting cylinders need 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 Blank any unused station on the base before pressurising.
- check Wiring by qualified personnel, per AirTAC documentation.
Airtac 3V2M Solenoid Valve 3V2MNOCI-18F FAQ
Eighteen NC 3/2 stations, direct-acting, spring return, coaxial shut-off, centralised exhaust. Cv 0.1, pressure 0-0.8 MPa, temperature -20 to 70 C, AC220V coil power 7 VA per station (about 126 VA total energised), IP65 (DIN 40050), PT1/8 ports, PT thread standard, manual override fitted, air filtered to 40 um or finer without lubrication.
Each 3/2 valve feeds a single outlet or vents it, so it drives single-acting spring-return cylinders, on/off air blow, clamping and pilot duty. It will not drive a double-acting cylinder, which requires a 5-port valve such as the AirTAC 4V series. It also has no vacuum rating, so do not apply it to negative-pressure circuits.
