Airtac 3V2M Solenoid Valve 3V2MNOF-9F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOF-9F 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 3V2MNOF-9F
The 3V2MNOF-9F is a complete nine-station bank of normally open 3/2 solenoid valves mounted on one shared 3V2M base. Every valve is direct-acting with a spring return and a coaxial poppet seat, so the whole bank runs from a single PT1/8 air supply and a single wiring run - when a station misbehaves, you trace one supply and one circuit instead of chasing nine separate valves.
Because the valves are normally open, each outlet passes air until its DC12V coil is energised, which suits fail-pressurised duties such as purge headers and default-release clamps. Each coil draws 7.0 W, so nine stations energised together pull 63 W, about 5.3 A at 12 V. Coils are rated IP65, flow is Cv 0.1 per station, a manual override sits on every valve for commissioning, and the NO state is factory-fixed: no gasket flip or field change can turn this bank into an NC one.

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 3V2MNOF-9F Is Used
Refrigerated trailer lock bank
Nine spring-return lock cylinders along a reefer trailer sidewall stay released through the normally open valves and lock on coil signal, all powered from the truck's 12 V battery without an inverter.
Bottle-rinse nozzle header
A nine-nozzle air rinse on a beverage line blows by default and stops each nozzle individually when its coil energises - a duty the NO state handles without extra logic.
Damper actuator test bench
An HVAC lab cycles nine damper actuators from one 12 V supply; each 3/2 station feeds or vents its spring-return cylinder while the shared base keeps wiring down to two runs.
Is the Airtac 3V2M Solenoid Valve 3V2MNOF-9F the Right Part?
Treat 3V2M as the density choice: Cv 0.1 per station is the price of routing everything through one base. If a single station needs more flow, hang an individual 3V2 valve there instead (Cv 0.18 at 1/8 in, Cv 0.19 at 1/4 in, and vacuum-rated); step up to 3V3 (Cv 0.62, 1/4 in, also vacuum-rated) for the highest flow in the 3V range, or use 3V1 where a 3.0 W DC draw matters more than flow.
Before ordering, fix five points: normally open state (which cannot be changed after purchase - flipping the dedicated base gasket does not convert it), DC12V coil, DIN plug entry, nine stations with centralised exhaust, and PT1/8 threads (G and NPT are catalogue options to order). If the machine includes a double-acting cylinder, that needs the 5-port AirTAC 4V series, not any 3/2 model.
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 3V2MNOF-9F FAQ
Each of the nine valves is a 3/2 direct-acting poppet with spring return: Cv 0.1, operating pressure 0-0.8 MPa (0-114 psi), media temperature -20 to 70 C, IP65 (DIN 40050) coils drawing 7.0 W on DC12V, PT1/8 ports and a manual override. Air must be filtered to 40 um or finer; lubrication is not required.
No. 3V2M uses a dedicated base gasket, and the catalogue states plainly that reversing or flipping that gasket does not change the initial state. The state is set at the factory, so order NO or NC correctly up front. Check the exact coil voltage and entry type against your panel before ordering.
