Airtac 3V2M Solenoid Valve 3V2MNCEI-18F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCEI-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 3V2MNCEI-18F
Eighteen NC 3/2 stations share one 3V2M base in the 3V2MNCEI-18F: 18 direct-acting, spring-return poppet valves with AC110V coils and lead-out wiring on PT1/8 ports. The price of this density is flow - Cv 0.1 per station, because the air path runs through the base rather than a straight individual valve body.
The gain is simpler engineering: one supply connection, one exhaust point, one wiring harness and 18 clearly numbered stations. With every coil energised the assembly draws about 18 x 7 VA = 126 VA, so check the margin on your AC110V transformer. Manual overrides on each body let technicians jog individual stations during commissioning.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNCEI-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. |
| 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. |
| 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 3V2MNCEI-18F Is Used
Sample handling automation
An analytical sampler uses 18 spring-return actuators to index vials; each NC station stays vented until its AC110V solenoid is energised by the lab controller.
CNC fixture clamping
A machining centre's fixture plate clamps 18 parts with single-acting cylinders fed from one manifold; the centralised exhaust routes spent air away from the cutting zone.
Parcel diverter bank
A distribution hub drives 18 divert gates from one base; the shared exhaust port simplifies ducting above the belt while 18 flying leads land in a single control enclosure.
Is the Airtac 3V2M Solenoid Valve 3V2MNCEI-18F the Right Part?
Confirm five things: the NC initial state (fixed at manufacture - no field conversion to NO exists), the AC110V coil, flying-lead entry, the 18-station count and centralised exhaust, plus thread (PT standard; order G or NPT if your piping is parallel or NPT). Cv 0.1 per station suits small cylinders and pilot duty; where a station demands more flow, use a stand-alone 3V2 valve (Cv 0.18 at 1/8 in or Cv 0.19 at 1/4 in, both vacuum-rated) or the 3V3 at Cv 0.62 for 1/4 in lines. Light, infrequent duty can drop to a 3V1 valve at 3.0 W DC. Double-acting cylinders require the 5-port AirTAC 4V family.
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 3V2MNCEI-18F FAQ
Each station: 3/2 NC function, Cv 0.1, 0-0.8 MPa pressure range, -20 to 70 C temperature, 7 VA AC110V coil, IP65 (DIN 40050) electrical protection, PT1/8 ports. Use air filtered to 40 um or better; a lubricator is not needed.
This assembly vents all 18 stations through one shared exhaust port, which keeps the plumbing short and the layout clean. If oil mist, noise or back-pressure from one station must not affect the others - for example on a food or electronics line - order the -D suffix for an independent exhaust at every station instead.
