Airtac 3V2M Solenoid Valve 3V2MNOFI-8F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOFI-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 3V2MNOFI-8F
Eight normally open 3/2 solenoid valves, pre-grouped on one 3V2M base: that is the 3V2MNOFI-8F in a line. Each valve is a direct-acting, single-solenoid unit with spring return and a coaxial poppet seat for clean shut-off, feeding or venting one outlet per station. While a coil is off, that outlet passes air; energise it and the station vents through the base's single centralised exhaust port.
Wiring is via flying leads (the I entry), so each coil arrives with pre-attached lead-out wires instead of a DIN socket - handy where a socket could work loose under vibration. The F voltage code is DC12V at 7.0 W per coil, so eight stations energised together load the supply with roughly 56 W, near 4.7 A at 12 V. Flow is Cv 0.1 per station through the base path, pressure 0-0.8 MPa, and protection is IP65 (DIN 40050).

Model Code: Airtac 3V2M Solenoid Valve 3V2MNOFI-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. |
| NO | Normally open: air passes 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. |
| 8F | 8 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 3V2MNOFI-8F Is Used
Part-cooling nozzle bank
Eight cooling-air nozzles above an injection-moulding take-out robot keep blowing while the line idles and cut off the moment each DC12V coil is energised.
Battery-fed agri robot
A 12 V lead-acid battery on a greenhouse row-closing cart feeds the flying leads straight from a fused distribution strip - no DIN sockets to seat in a dusty cab.
Bottling line stopper gates
Spring-return stopper cylinders on a bottle conveyor are fed air while idle and vent to release the bottles the instant each coil is energised.
Is the Airtac 3V2M Solenoid Valve 3V2MNOFI-8F the Right Part?
Choose the 3V2M family when you need many valves packed closely and can trade some flow for density: through the base each station is Cv 0.1, against a standalone 3V2's Cv 0.18 at 1/8 in or 0.19 at 1/4 in. Step up to 3V3 (Cv 0.62 at 1/4 in) where a circuit needs the most flow the 3V range offers, or down to 3V1 at 3.0 W DC for light, low-draw duties. A 3/2 valve cannot drive a double-acting cylinder - for those, move to the AirTAC 4V series.
Lock five points before ordering: normally open state, DC12V coil, flying-lead entry, eight stations and centralised exhaust, plus thread (PT is standard on this family; G and NPT are order options). The NO state is fixed at purchase - no gasket reversal or field change converts it to NC, so order NC if the outlet must be closed at rest.
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 3V2MNOFI-8F FAQ
Each valve is a 3/2 direct-acting poppet type with a flow coefficient of Cv 0.1, operating pressure 0-0.8 MPa (0-114 psi), media temperature -20 to 70 C and IP65 (DIN 40050) protection. Coils are DC12V at 7.0 W, so eight stations energised together draw about 56 W - roughly 4.7 A at 12 V. Ports are PT1/8, with a manual override fitted for commissioning.
No. The initial state is fixed when the valve is made and ordered, and nothing done on site changes NO into NC. Reversing or flipping the dedicated base gasket does not convert the state - the catalogue states this explicitly. If your circuit must be closed at rest, order the NC version up front.
