Airtac 3V2M Solenoid Valve 3V2MNOBI-19F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOBI-19F 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 3V2MNOBI-19F
The 3V2MNOBI-19F is a complete 19-station manifold: nineteen normally open 3/2 poppet valve bodies seated on a single 3V2M base with one shared PT1/8 air supply and one centralised exhaust. Each valve is direct-acting, single solenoid, spring return, with coaxial shut-off sealing. Because the valves sit on a common base, one wiring harness runs the whole bank, so when a circuit misbehaves you trace stations along the manifold instead of hunting nineteen separate valves.
This configuration is wired for DC24V through flying leads, each valve carrying its own 7.0 W pre-wired lead-out rather than plugging a DIN coil connector per station. Outlets stay open to flow while each coil is de-energised and shut when energised. IP65 (DIN 40050) protection and a manual override on every body make set-up straightforward. Air must be filtered to 40 um or finer; lubrication is not required.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNOBI-19F
| 3V2M | Body — sets the flow, the coil power and whether vacuum is rated. |
|---|---|
| 1/8 in | Port size. M5, 06 = 1/8 in, 08 = 1/4 in, 10 = 3/8 in. |
| NO | Normally open: air passes until the coil is energised. |
| DC24V | Coil voltage. A = AC220V, B = DC24V, C = AC110V, E = AC24V, F = DC12V. |
| I | Electrical entry: I = flying lead, otherwise a DIN plug. |
| 19F | 19 stations in one assembly, centralised exhaust. |
| PT | Port thread. PT ships from stock; G and NPT are available to order. |
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 3V2MNOBI-19F Is Used
Textile air-jet manifold bank
Normally open valves let weft air-jet nozzles blow continuously while the loom is unpowered and cut each jet only on command - a 19-station block matches a 19-nozzle shedding or picking array on one supply.
Packaging line spring-return grippers
A row of single-acting gripper cylinders that release open by spring under power loss is fed point by point from this manifold; de-energising a station vents nothing, it re-opens the flow to its gripper.
Bottle-filling blow-off panel
Bottle-rinse and label-blow nozzles around a rotary filler are switched in groups from one base, so a single 24 V harness and one supply line serve all 19 points and a failed station is swapped without rewiring.
Is the Airtac 3V2M Solenoid Valve 3V2MNOBI-19F the Right Part?
Pick 3V2M when you want many stations on one base and can live with Cv 0.1 per valve - the flow path crosses the base, which is why this density costs flow versus the individually-ported 3V2 (Cv 0.18 at 1/8 in, 0.19 at 1/4 in, vacuum-rated). If any single station must pass more air or see vacuum, mount a 3V2 or a 3V3 (Cv 0.62, 1/4 in, vacuum-rated) there instead. 3V1 is the low-power alternative at 3.0 W DC for light-duty points. If your actuator is a double-acting cylinder, no 3/2 valve fits - you need a 5-port 4V valve.
Match these five points before ordering: initial state (this item is normally open, fixed at manufacture - the base gasket cannot be flipped to convert it), coil voltage (DC24V), electrical entry (flying lead), station count (19F), and exhaust style (centralised here; choose -D suffix for independent exhaust per station). Thread is PT as standard; G and NPT are order options - confirm from the datasheet if you need them.
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 3V2MNOBI-19F FAQ
Nineteen 3/2 direct-acting single-solenoid spring-return poppet valves on a 3V2M base. Normally open initial state. DC24V coils at 7.0 W each, flying lead entry, PT1/8 ports, centralised exhaust, PT thread. Cv 0.1 per valve (a flow coefficient, not a flow rate). Operating pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, IP65 (DIN 40050), air filtered to 40 um or finer, manual override fitted, no lubrication required.
No. On 3V2M the initial state is built into the valve body and the dedicated base gasket cannot be reversed or flipped to convert NC to NO or the reverse - AirTAC states this explicitly. Order the state you need up front. Also plan the 24 V supply for the worst case: with all 19 DC coils energised the bank draws about 133 W, roughly 5.5 A at 24 V.
