Airtac 3V2M Solenoid Valve 3V2MNCF-18F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCF-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 3V2MNCF-18F
The 3V2MNCF-18F arrives as a ready-made bank: eighteen normally closed 3/2 valve bodies snapped onto one dedicated 3V2M base, all sharing a single PT1/8 supply and one common exhaust route. Each valve is a direct-acting, spring-return popet unit with coaxial shut-off, and every coil runs on DC12V at 7.0 W through a standard DIN plug connection. Nothing passes to any station outlet until that coil is energised, so the whole bank sits safely dormant at rest.
Because eighteen DC coils share one wiring run, size the 12 V supply for the worst case: all stations energised at once draws about 126 W, roughly 10.5 A. That single shared harness is also the diagnostic advantage - a fault shows up as one station behaving differently from its seventeen identical neighbours, which makes commissioning and fault-finding faster than tracing eighteen separate valve kits. Each body carries a manual override for setup without power, the coil is IP65 (DIN 40050), and the bank handles 0-0.8 MPa in air filtered to 40 um or finer with no lubrication needed.

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 3V2MNCF-18F Is Used
Rotary indexing table clamps
Eighteen spring-return clamp cylinders around a dial plate each need feed-or-vent control from one shared supply; the NC state keeps every clamp vented until its station is deliberately energised.
Lab sample stoppering station
A 96-well filling rig uses per-well blow-off and stopper-press stations; the 18-station bank drives the single-acting air pins in coordinated groups from one wiring harness at 12 V.
Carton divert jets on a packaging line
Sorting conveyors fire short bursts of air to push cartons down a lane; a dense NC manifold gives one air pulse valve per divert position, all venting to a single common exhaust port.
Is the Airtac 3V2M Solenoid Valve 3V2MNCF-18F the Right Part?
Choose this assembly when you need maximum station density: the base-mounted layout packs eighteen valves into one manifold, trading flow for compactness at Cv 0.1 per station. If any single duty needs more passage, put an individually-ported AirTAC 3V2 in that position (Cv 0.18 at 1/8 in, 0.19 at 1/4 in, and vacuum-rated); step to 3V3 (Cv 0.62, 1/4 in, vacuum-rated) for the highest flow in the 3V range, or pick 3V1 (3.0 W DC) where coil power matters more than density. A double-acting cylinder needs a 5-port AirTAC 4V valve, not this 3/2 unit.
Confirm five points before ordering: initial state (this SKU is NC and cannot be changed afterwards - the base gasket cannot be flipped or reversed to convert it), coil voltage (DC12V here), electrical entry (DIN plug; the I suffix orders flying leads instead), station count (18F), and exhaust style (centralised; order the D suffix for independent per-station exhaust). PT is the standard thread; G and NPT are order options.
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 3V2MNCF-18F FAQ
It is an 18-station 3V2M assembly of normally closed 3/2 direct-acting solenoid valves on a shared base. Flow coefficient Cv 0.1 per valve (a coefficient, not a flow rate), operating pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, DC12V coils at 7.0 W each, IP65 (DIN 40050), PT1/8 ports with centralised exhaust, air filtered to 40 um or finer, no lubrication required. For response time, weight or dimensions, confirm from the datasheet via RFQ.
No. The 3V2M initial state is fixed at order. Reversing or flipping the dedicated base gasket does NOT convert NC to NO - the catalogue states this explicitly - so a normally open position must be ordered as an NO SKU from the start. Also note each 3/2 valve has three ports (supply, outlet, exhaust) and drives single-acting spring-return cylinders, blow-off, clamping or pilot duty; a double-acting cylinder requires a 5-port AirTAC 4V valve instead.
