Airtac 3V2M Solenoid Valve 3V2MNCFI-20F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCFI-20F 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 3V2MNCFI-20F
Twenty stations on one manifold is the full-size expression of the 3V2M concept, and the 3V2MNCFI-20F delivers it complete: twenty normally closed 3/2 poppet valves, DC12V coils of 7.0 W each on flying leads, a single shared air supply and one centralised exhaust path for the whole row. Every station is direct-acting with spring return, Cv 0.1, PT1/8 threads.
At this width the electrical side deserves respect: 20 x 7.0 W is 140 W with all coils energised, close to 11.7 A on a 12 V rail, so cable cross-section and supply rating must be planned for the entire bank rather than valve by valve. The reward is maintenance discipline - one wiring run, one supply point and a manual override on each body make a station-by-station checkout a short afternoon's work. Confirm that normally closed is the required initial state when ordering; it cannot be converted afterwards by any gasket trick.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNCFI-20F
| 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. |
| DC12V | Coil voltage. A = AC220V, B = DC24V, C = AC110V, E = AC24V, F = DC12V. |
| I | Electrical entry: I = flying lead, otherwise a DIN plug. |
| 20F | 20 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 3V2MNCFI-20F Is Used
Distribution board actuation
Twenty discrete pneumatic outputs on a machine's air board - gates, stops, chutes and clamps - run from one manifold row, replacing twenty loose valves and their separate fittings and wiring.
Bottling line fill heads
Fill, purge and capping cylinders along a bottling line are grouped station by station on one bank, so an entire machine section is supplied and wired from a single point.
Palletiser sort gates
Divert and gate cylinders steering cases onto pallet lanes hang off one 20-station bank, with the centralised exhaust keeping vented air routed clear of the lane sensors.
Is the Airtac 3V2M Solenoid Valve 3V2MNCFI-20F the Right Part?
Before committing, tick the five defining choices in this code: NC initial state, DC12V coil, flying-lead entry, 20 stations and centralised exhaust, all on PT thread as the family default - G and NPT versions exist but must be ordered as such. Remember the state decision is irreversible once the order is placed.
For flow, treat this bank as the high-density option at Cv 0.1 per station. Any station needing more passage is better served by an individual 3V2 (Cv 0.18 at 1/8, 0.19 at 1/4, vacuum-rated) or, for the largest duty, a 3V3 at Cv 0.62 and 1/4; where the duty is light and power is tight, 3V1 at 3.0 W DC is the economical body. Double-acting cylinders call for a 5-port design - 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 3V2MNCFI-20F FAQ
Twenty 3/2 normally closed stations, each direct-acting and spring return; Cv 0.1 per station; operating pressure 0-0.8 MPa (0-114 psi); temperature -20 to 70 C; DC12V coils at 7.0 W each (about 140 W, near 11.7 A at 12 V if all 20 energise); IP65 (DIN 40050); PT1/8 ports; air filtered to 40 um or finer.
All twenty stations vent through one shared exhaust port on the base, which simplifies piping and lets you collect or silence the vent air in one place. If each station instead needs its own exhaust route - for example to keep venting away from sensitive areas - the D-suffix versions of the 3V2M base provide independent exhaust per station and are ordered separately. Exhaust routing is fixed by the base you order, as is the NC/NO state, so both decisions belong on the purchase order.
