Airtac 3V2M Solenoid Valve 3V2MNCBI-7F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCBI-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 3V2MNCBI-7F
The 3V2MNCBI-7F packs seven normally closed, direct-acting 3/2 poppet valves onto one 7F manifold base, all spring-return and all with 7.0 W DC24V flying-lead coils. Every outlet sits vented until its coil is powered, so a machine stop or a controller fault leaves all seven actuator circuits safely dumped.
At seven stations the diagnostic value of the shared architecture starts to pay: one PT1/8 supply port, one centralised exhaust port and one wiring run serve all seven functions, so a sticky circuit is isolated by moving a single valve body along the base instead of re-plumbing the machine. Stations may be mixed or expanded later, and the CV 0.1 flow per valve keeps small-bore actuation tidy - though each coil adds 7.0 W, so seven on together is about 49 W. The NC state is factory-set and permanent.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNCBI-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. |
| NC | Normally closed: no air at the outlet until the coil is energised. |
| DC24V | 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 3V2MNCBI-7F Is Used
Assembly-station tool clamps
A seven-position automotive sub-assembly line clamps a housing at each station; the NC valves release all clamps by spring the instant the 24 V control rail drops.
Test-rig solenoid bank
An end-of-line electrical test rig switches seven pneumatic loads from one manifold, cutting panel wiring to a single loom instead of seven separate DIN connectors.
Paint-booth atomising zones
A spray booth splits atomising air into seven zones, each opened only while energised and vented to the common exhaust between coats to stop drips at the gun.
Is the Airtac 3V2M Solenoid Valve 3V2MNCBI-7F the Right Part?
Seven manifolds at Cv 0.1 cover clamping, blowing and pilot duty, but if any single station must pass more air, pair this base with individual AirTAC 3V2 bodies (Cv 0.18 at 1/8 in, Cv 0.19 at 1/4 in, both vacuum-rated) or a 3V3 at Cv 0.62 for the heaviest duty; a 3V1 at 3.0 W DC is the thrifty choice for tiny loads. Double-acting cylinders are outside 3/2 territory - specify the AirTAC 4V 5-port series for those.
Order by the five-point check: NC state, DC24V coil, flying-lead entry, seven stations, centralised exhaust, then thread (PT standard; G or NPT on request). There is no post-purchase path from NC to NO - not the gasket, not rewiring - so get the state right in the order.
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 3V2MNCBI-7F FAQ
Budget per station, not per average: each DC24V coil takes 7.0 W, so all seven energised at once is 49 W, roughly 2 A at 24 V before control overhead. A supply sized only for the valves that usually run will trip when a fault calls every station on simultaneously.
Each station is a 3/2 poppet valve: supply, outlet and exhaust, two positions, spring returned. It pilots cylinders, clamps, blow nozzles and single-acting (spring-return) actuators at Cv 0.1, 0-0.8 MPa and -20 to 70 C. It cannot run a double-acting cylinder - that needs both an outlet and a second line, so use the AirTAC 4V series.
