Airtac 3V2M Solenoid Valve 3V2MNOB-7F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOB-7F 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 3V2MNOB-7F
The 3V2MNOB-7F is a complete manifold assembly: seven normally open 3/2 valve bodies pre-mounted on one dedicated base. Every station is direct-acting with a single DC24V solenoid and spring return, built on a coaxial poppet that seals well, and each coil draws 7.0 W while IP65 (DIN 40050) protects the electrical side. Because the valves are NO, air passes through to all seven outlets while power is off, and each coil must be energised to close its station.
The shared base feeds all stations from one supply and one wiring harness, so a fault shows up fast against a common reference. Exhaust air from all seven stations is routed to a single centralised port. Manual override buttons on each body help during setup and commissioning.

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 3V2MNOB-7F Is Used
PCB blow-off nozzle bank
Seven normally open points on one base feed air knives that blow dust off circuit boards on a conveyor line; the coils are energised only when a zone must be shut off.
Fail-supplied welding fixture clamps
On a spot-welding fixture, NO stations keep pneumatic clamps fed while control power is down, so a blackout does not drop the workpiece.
Drilling table hold-downs
A bench drilling station uses normally open valves to hold pneumatic hold-downs against a plate until the coil is energised to release it.
Is the Airtac 3V2M Solenoid Valve 3V2MNOB-7F the Right Part?
3V2M trades flow for manifold density: Cv 0.1 through the base. If any one station needs more air, fit an individual 3V2 (Cv 0.18 at 1/8, 0.19 at 1/4, vacuum rated) or step to 3V3 (Cv 0.62, 1/4); 3V1 at 3.0 W DC is the low-power choice for light duty. These are single-acting drives - for a double-acting cylinder you need a 5-port AirTAC 4V valve.
Fix five things before you order: initial state (NO here - it cannot be converted afterwards, and flipping the base gasket does not change it), coil voltage (DC24V), electrical entry (DIN plug on this code), station count (7F) and exhaust type (centralised). Thread is PT as standard; G and NPT are catalogue options to order.
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 3V2MNOB-7F FAQ
Seven NO 3/2 stations on one base; Cv 0.1 per station; operating pressure 0-0.8 MPa (0-114 psi); temperature -20 to 70 C; DC24V coils at 7.0 W each (AC builds of this family run 7 VA); IP65 to DIN 40050; PT1/8 ports; medium is air filtered to 40 um or finer, lubrication not required.
NO means each outlet passes air while the coil is off and cuts it when energised - useful where a power loss must leave the circuit fed. The state is set at the factory: the dedicated base gasket cannot be flipped to convert NO to NC, and no field conversion exists, so order the correct state. It drives single-acting cylinders and blow or pilot duties, not double-acting cylinders (use AirTAC 4V).
