Airtac 3V2M Solenoid Valve 3V2MNCB-16F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCB-16F 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 3V2MNCB-16F
Sixteen normally closed 3/2 valves, one base: the 3V2MNCB-16F is a 16-station assembly with DC24V coils on DIN plugs, a centralised exhaust port and PT1/8 connections. Every body is a direct-acting, single-solenoid, spring-return unit built around a coaxial shut-off poppet. With centralised exhaust, all sixteen stations vent through the base's common exhaust, which keeps piping short - route that single exhaust line where waste air and noise are acceptable.
Because the exhaust is shared, one silencer and one duct serve the whole bank. The NC logic means each outlet stays vented until its coil is energised, which is the safe default for clamps and gates that must release on power loss. IP65 (DIN 40050) coil protection and a manual override on each station round out the package. And one warning the catalogue states plainly: reversing the dedicated base gasket does not convert NC to NO - the state is fixed by the valves you 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 3V2MNCB-16F Is Used
PLC I/O air interface
Sixteen NC outputs on one manifold mirror sixteen PLC digital points, each switching a pilot or clamp line from a common DC24V rail.
Stamping press feed gates
High-cycle single-acting feed and eject gates around a press, releasing safely to the shared exhaust whenever a coil drops out.
Lab automation manifold
Sixteen on/off air functions - purges, lifts, caps - packed into one base inside a compact analytical instrument enclosure.
Is the Airtac 3V2M Solenoid Valve 3V2MNCB-16F the Right Part?
This code fixes five choices for you: NC initial state, DC24V coil, DIN plug entry, 16 stations and centralised exhaust, on PT1/8 (PT is the standard thread here; order G or NPT as a catalogue option). If your machine would be noisier or dirtier with a shared exhaust, the same bank exists with independent exhaust - add D to the code. NC/NO cannot be changed after delivery.
Flow is Cv 0.1 per station because air passes through the base - that is the trade-off for 16 valves on one manifold. A single high-flow station is better served by a separate 3V2 (Cv 0.18 at 1/8 in, Cv 0.19 at 1/4 in, vacuum-rated) or a 3V3 (Cv 0.62, 1/4 in, vacuum-rated); 3V1 at 3.0 W DC suits light, low-power duty. Double-acting actuators need the AirTAC 4V 5-port series, not this 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 3V2MNCB-16F FAQ
The base (no D code) routes all sixteen stations to one common exhaust, so a single silencer serves the bank and piping stays minimal. Specifications: 3/2 NC, direct-acting, spring return, Cv 0.1, pressure 0-0.8 MPa, temperature -20 to 70 C, DC coil 7.0 W per station, IP65 (DIN 40050), ports PT1/8.
No. 3V2M uses a dedicated base gasket and flipping that gasket does not convert NC to NO - the manufacturer states this explicitly. The normally closed function is built into the valve bodies as ordered, so select NC only after confirming the de-energised = vented behaviour your machine requires.
