Airtac 3V2M Solenoid Valve 3V2MNCB-11F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCB-11F 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-11F
The 3V2MNCB-11F is specified normally closed for a reason: until a DC24V coil is energised, its station holds the outlet vented, so no air reaches the actuator. That fail-quiet behaviour suits clamping, holding and interlock duty where valves must not leak through on power loss. Each of the eleven positions carries a direct-acting, single-solenoid, spring-return poppet valve with a DIN plug and a manual override.
All eleven valves share one supply gallery and one wiring run on the common base, and all vents merge into a single centralised exhaust port - convenient when a duct or silencer can be placed at one point. Each flow path is Cv 0.1, sealed by the coaxial poppet construction, and the coil power is 7.0 W per DC station.

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-11F Is Used
Press-brake guard interlocks
NC valves keep downstream lines vented whenever control power drops, so hold-downs release only under an explicit DC24V command.
Vial-capping station, lab automation
Eleven spring-return capper actuators across a sample line are switched individually from one manifold with shared filtered air.
Eleven-branch air logic panel
Machine builders use the assembly as a compact ON/OFF logic bank, replacing eleven separate body-and-foot-mount valves with one base.
Is the Airtac 3V2M Solenoid Valve 3V2MNCB-11F the Right Part?
The NC choice here is permanent. AirTAC's dedicated 3V2M base gasket cannot be reversed to swap the initial state, so confirm whether the outlet must vent or pass when de-energised before you order; the NO equivalent is the 3V2MNOB-11F. Then fix the remaining points: DC24V coil, DIN plug entry (flying-lead -I as a code option), 11 stations, centralised exhaust and PT thread - G and NPT are catalogue alternatives.
If a single station moves a larger cylinder, the base limits flow to Cv 0.1; a standalone 3V2 reaches Cv 0.18 at 1/8 in (0.19 at 1/4 in, vacuum-rated) and a 3V3 reaches Cv 0.62 at 1/4 in (vacuum-rated). Where power draw matters more than flow, the 3V1 runs at just 3.0 W on DC. Double-acting cylinders require the 5-port AirTAC 4V series.
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-11F FAQ
Flow coefficient Cv 0.1 per valve path, pressure range 0-0.8 MPa (0-114 psi), temperature range -20 to 70 C, and IP65 protection (DIN 40050). Coils are DC24V at 7.0 W each; AC members of the 3V2M family draw 7 VA. Air must be filtered to 40 um or better.
Every 3/2 station has three ports and two states: it feeds the outlet or vents it. That suits single-acting spring-return cylinders, air blow, clamping and pilot duty. It cannot drive a double-acting cylinder, which needs simultaneous pressurise and exhaust - use the AirTAC 4V series there.
