Airtac 3V2M Solenoid Valve 3V2MNOFI-7F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOFI-7F 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-7F
In the 3V2MNOFI-7F the 7-station base uses centralised exhaust: all seven 3/2 valves vent into one shared port, which keeps the manifold's outer face clean and silencing simple - one muffler serves the group instead of seven loose vents. The valves themselves are normally open, so outlets carry air until each DC12V coil is energised and the spring vents that line. Construction is direct-acting with a coaxial shut-off poppet.
Flow is Cv 0.1 per station at 0-0.8 MPa, with IP65 coils drawing 7.0 W each - about 49 W, near 4 A at 12 V, for a fully energised seven. Wiring converges on one shared point of the base, which shortens fault-finding to coil-by-coil checks. Should a station later need to vent separately, that is the D (independent exhaust) version of the same family. Genuine AirTAC valves and base; PT thread standard.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNOFI-7F
| 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. |
| 7F | 7 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-7F Is Used
Modular gripper panel
A pick panel with seven spring-return grippers assigns one 3V2M station per gripper; adding an eighth gripper means adding a valve and base station, not redesigning the manifold.
Parcel diverter arms
A sorting hub runs seven diverter arms along the sorter, each needing one 3/2 signal valve; centralised exhaust lets the frame carry a single muffler rather than seven loose vents.
Fail-open vent circuits
On a furnace-door interlock panel, seven NO valves hold vent paths open so doors cannot remain clamped if the 12 V control circuit fails.
Is the Airtac 3V2M Solenoid Valve 3V2MNOFI-7F the Right Part?
This assembly wins on count, not on flow: Cv 0.1 per station through the shared base, so step to a standalone 3V2 (Cv 0.18 at 1/8 in, 0.19 at 1/4 in, vacuum-rated) or a 3V3 (Cv 0.62, 1/4 in, vacuum-rated) wherever one output needs more air; drop to 3V1 at 3.0 W DC for light duty. Confirm the order code before checkout: initial state NO, coil DC12V, flying-lead entry, 7 stations, centralised exhaust, PT thread standard with G or NPT to order. The state is permanent - a normally open 3/2M cannot be turned normally closed after purchase by any means, including the base gasket, which is not reversible. Double-acting cylinders need an AirTAC 4V 5-port valve.
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-7F FAQ
Seven NO 3/2 valves on a 7F base: Cv 0.1 per station, 0-0.8 MPa (0-114 psi), -20 to 70 C, DC12V coil 7.0 W each (about 49 W, near 4 A at 12 V, all energised), IP65 to DIN 40050, PT1/8 threads.
Decide by fail state: NO keeps the outlet fed when power drops, NC shuts it. A 3V2M cannot be converted later - the dedicated base gasket does not reverse the state - so the initial state must be right when ordering. This 7F assembly is NO; for closed-at-rest duties order the NC version of the same code.
