Airtac 3V2M Solenoid Valve 3V2MNOB-9F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOB-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 3V2MNOB-9F
The 3V2MNOB-9F puts nine normally open valve bodies on a single shared base, so one supply line and one wiring loom serve the whole group. Every DC24V coil is rated 7.0 W, which means a worst case of about 63 W with all nine energised - roughly 2.6 A at 24 V - so size the power supply for that figure rather than for one valve.
Each station is a direct-acting, spring-return 3/2 poppet valve: air flows through while the coil is off and shuts off when it is energised. Manual overrides on every body, IP65 protection, and a -20 to 70 C operating window cover typical factory floor conditions.

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-9F Is Used
Assembly-cell single-acting grippers
Nine normally open stations each drive a spring-return gripper on an assembly cell, holding parts while coils are off and releasing on demand.
Control-cabinet valve group
All nine DIN plug coils connect into one cabinet wiring loom, so the machine builder terminates one harness instead of nine separate drop points.
Pneumatic belt stops along a conveyor
A conveyor line fits a normally open valve at each stop position, keeping the stop cylinders pressurised until the control system energises a coil to release a product.
Is the Airtac 3V2M Solenoid Valve 3V2MNOB-9F the Right Part?
Nine DC24V coils at 7.0 W mean about 63 W and roughly 2.6 A at 24 V with every station energised - budget the PSU on that worst case. Flow per station is Cv 0.1 through the shared base; where a point demands more, use a standalone 3V2 (Cv 0.18 at 1/8, 0.19 at 1/4, vacuum rated) or 3V3 (Cv 0.62, 1/4), and 3V1 at 3.0 W DC covers low-power duty. For double-acting cylinders, move to the AirTAC 4V series.
Before ordering, lock in: normally open state (not convertible later - the dedicated base gasket cannot flip it), DC24V, DIN plug entry, 9 stations, centralised exhaust, PT threads (G and NPT are order options).
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-9F FAQ
Cv 0.1 per station, pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, DC24V coil power 7.0 W per valve (AC builds of the family run 7 VA), IP65 (DIN 40050), PT1/8 ports. Nine coils fully on is about 63 W, near 2.6 A at 24 V - size the supply on that worst case.
Each 3/2 station has three ports and two states, feeding or venting one outlet - suited to single-acting spring-return cylinders, on/off blow, clamping and pilot duty. A 3V2M valve cannot drive a double-acting cylinder; that needs a 5-port valve such as AirTAC 4V. The NO state here means air passes when de-energised, and the initial state is not convertible after purchase.
