Airtac 3V2M Solenoid Valve 3V2MNOC-20F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOC-20F 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 3V2MNOC-20F
Twenty NO valve bodies share one 20-station 3V2M base in the 3V2MNOC-20F, fed by a single air supply and wired from one AC110V feed through DIN plug connections. Because each valve is normally open, air passes to every PT1/8 outlet while power is off, and energising a coil shuts that station down, so functions stay live through a control failure. Each position is a direct-acting, spring-return coaxial shut-off poppet with a flow coefficient of Cv 0.1.
Plan the electrical side before ordering: every AC coil draws 7 VA, so a bank with all twenty stations energised at once presents roughly 140 VA to the transformer. The centralised exhaust sends all venting through one common port on the base, IP65 protection (DIN 40050) covers the coils, and a manual override on each body helps during installation 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 3V2MNOC-20F Is Used
PCB test fixture with 20 spring probes
A bed-of-nails fixture lifts twenty spring-loaded probes from one manifold; with NO valves the probes stay up while the bench is off and retract station by station when each AC110V coil is energised.
Bottling line reject gates
One valve per reject lane lets the filler run with gates open while controls are dead and close a lane only on command, a fail-live behaviour the NO state provides.
Cable test rig, 20 circuits
A wiring analyser sequences twenty air-actuated relay contacts from one shared supply; shared wiring across the 20-station base keeps the control cabinet down to a single AC110V feed.
Is the Airtac 3V2M Solenoid Valve 3V2MNOC-20F the Right Part?
Choose the 3V2MNOC-20F when station density matters more than flow per station: Cv 0.1 per position suits small single-acting cylinders and light pilot duty, while a standalone 3V2 gives Cv 0.18 at 1/8 inch or 0.19 at 1/4 inch, and a 3V3 reaches Cv 0.62 at 1/4 inch where a station needs more air; the 3V1 at 3.0 W DC is the low-power choice for light duties. Double-acting cylinders need a 5-port valve from the AirTAC 4V series instead.
Lock six choices into your order: NO (or NC) initial state, AC110V coil voltage, DIN plug entry, the 20-station count, centralised exhaust, and thread, where PT is the family standard with G and NPT as catalogue options. The initial state is fixed by the dedicated base gasket and cannot be swapped after purchase, so order it correctly first time.
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 3V2MNOC-20F FAQ
Each of the twenty positions is a 3/2 direct-acting valve with flow coefficient Cv 0.1, operating pressure 0-0.8 MPa, working temperature -20 to 70 C and IP65 protection (DIN 40050). The AC110V coil draws 7 VA. Ports are PT1/8, with G and NPT as order options, and the twenty stations share one supply and one centralised exhaust.
No. The initial state is set by the dedicated base gasket, and reversing or flipping that gasket does not convert NC to NO on the 3V2M family, so order the state you need up front. Each station also drives single-acting or spring-return loads, on/off blow and pilot duty only; a double-acting cylinder requires a 5-port AirTAC 4V valve.
