Airtac 3V2M Solenoid Valve 3V2MNOA-15F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOA-15F 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 3V2MNOA-15F
A normally open valve is the correct pick where the process must keep receiving air through a power failure, and the 3V2MNOA-15F provides fifteen such circuits in one machined block. Each station is a 3/2 direct-acting poppet valve with spring return, an AC220V coil drawing 7 VA, and Cv 0.1 of flow through the shared base gallery. Energise a station and it vents; cut the power and it passes air again without any stored command.
Mounting fifteen valves on one base collapses the plumbing into a single assembly: one supply, one connector set, one exhaust path. Air leaves centrally through the base, so a lone silencer serves all fifteen stations. The NO initial state is set at the factory - AirTAC's dedicated base gasket cannot be reversed to convert NO to NC, so settle the state before ordering.

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 3V2MNOA-15F Is Used
Glove box inerting jets
A powder-handling glove box keeps fifteen purge jets flowing through NO stations, so inerting continues automatically whenever the controls lose power.
Glue-dot applicator nozzles
A corrugated box gluing head runs fifteen nozzles, each nozzle's supply cut by its own NO station the instant the controller signals a pattern stop.
Process valve pilot bank
Fifteen large process valves are piloted from one 3V2M base; the NO pilot logic keeps each main actuator fed if the PLC supply fails, holding the process in its safe state.
Is the Airtac 3V2M Solenoid Valve 3V2MNOA-15F the Right Part?
Confirm five things before you buy: normally open state, AC220V voltage, DIN plug entry, fifteen stations, centralised exhaust, and thread (PT standard; G and NPT are order options). There is no field conversion - the NO state lives in the valve bodies, and flipping the dedicated base gasket changes nothing.
Flow-wise the 3V2M trades Cv 0.1 per station for base-mounted density. An individually ported 3V2 gives Cv 0.18 at 1/8 in or Cv 0.19 at 1/4 in plus a vacuum rating; step up to the 3V3 (Cv 0.62, 1/4 in) for the most air the 3V family delivers. If coil draw is the concern, the 3V1 needs only 3.0 W on DC. Double-acting cylinders need 5 ports - that is the 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 3V2MNOA-15F FAQ
Fifteen 3/2 normally open stations, Cv 0.1 each, pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, IP65 (DIN 40050) and a manual override on every valve. AC220V coils at 7 VA apiece give 105 VA connected; DC builds of the family draw 7.0 W per coil. Ports are PT1/8, with G and NPT as order options.
This assembly vents exhaust through one shared port on the base, so a single silencer and duct serve all fifteen stations - compact and simple, but back-pressure is shared between stations. If a circuit must vent on its own, order the -D independent-exhaust version of the base instead.
