Airtac 3V2M Solenoid Valve 3V2MNOC-18F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOC-18F 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-18F
The 3V2MNOC-18F is a complete 18-station manifold assembly: eighteen 3/2 normally open valve bodies pre-matched to an 18F base, all drawing from one common air supply and one wiring run. Each valve is direct-acting with a single solenoid and spring return, built as a coaxial shut-off (poppet) construction for tight sealing. Because the initial state is normally open, every station passes air from supply to outlet while de-energised and vents the outlet only when its 7 VA AC110V coil is switched on - useful where a power failure must leave the outlets flowing rather than dead-ended.
Eighteen coils on one base is a serious electrical load, so plan it: at 7 VA per AC coil, a fully energised 3V2MNOC-18F draws roughly 126 VA, and every station you add on a larger base adds another 7 VA to the budget. The DIN plug entry keeps each connection tool-friendly, a manual override on every body helps you prove out plumbing before power is applied, and coils are protected to IP65 (DIN 40050). Note that the flow path runs through the base, so each station is Cv 0.1 - the price of this manifold density. The normally open state is fixed at order: reversing the dedicated base gasket does NOT convert NO to NC, so confirm the state before you buy.

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-18F Is Used
Bottling line hold-down rings
Eighteen normally open circuits keep hold-down and stabiliser cylinders extended along a bottle conveyor with no power applied; each station vents its cylinder only when the AC110V coil is pulsed for a changeover or stop.
Fixture pallet clamp bank
A CNC fixture pallet with up to 18 spring-return swing clamps runs from one 3V2MNOC-18F base: clamps stay actuated by spring air when unpowered, and energising a station releases that clamp for loading.
Print roll cleaning blow-off
A web printing machine uses the eighteen stations for zone-by-zone air knives that clean ink from guide rolls, all exhausting through the centralised port and fed from one filtered supply with a 40 um element.
Is the Airtac 3V2M Solenoid Valve 3V2MNOC-18F the Right Part?
Choose this assembly when many stations must share one supply and one wiring run and the duty at each port is small: 18 stations at Cv 0.1 each suits pilot duty, low-flow clamping and zone blow-off. If any single station needs more flow than Cv 0.1, do not stretch the manifold - put an individually-ported 3V2 there instead (Cv 0.18 at 1/8 in, 0.19 at 1/4 in, and vacuum-rated) or a 3V3 for the highest flow in the range (Cv 0.62, 1/4 in). Where the duty is light and coil heat matters, the 3V1 family is the lower-power option at 3.0 W DC. If a station must drive a double-acting cylinder, none of the 3V valves fit - specify a 5-port AirTAC 4V valve.
Match five points to your drawing: initial state NO (this code; it cannot be changed afterwards by flipping the gasket or any other means), coil voltage AC110V, electrical entry DIN plug, 18 stations on the 18F base, and centralised exhaust (all stations vent through a shared port - order the independent-exhaust D variant if zones must vent separately). PT is the standard thread; G and NPT are order options.
Confirm before you order

- ✓ Initial state — NC or NO, ordered up front
- ✓ Coil voltage matches your controller output

- ✓ 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-18F FAQ
It is an 18-station normally open 3/2 manifold assembly with AC110V coils at 7 VA each (DC versions of the series draw 7.0 W), DIN plug entry, PT ports and a flow coefficient of Cv 0.1 per station. Operating pressure is 0-0.8 MPa (0-114 psi), temperature range is -20 to 70 C, protection is IP65 (DIN 40050), and the medium is air filtered to 40 um or finer with no lubrication required. Manual overrides are fitted for commissioning.
Normally open means every station feeds its outlet while de-energised and vents only when the 7 VA coil is switched on - the right choice for hold-down clamps, cooling jets and any function that must stay live through a power cut. This state is set by the valve internals and is fixed at order: flipping or reversing the dedicated base gasket does NOT convert NO to NC, so a normally closed station must be ordered as a separate NC code. Also note each port drives single-acting (spring-return) cylinders, blow-off, clamping or pilot duty - not a double-acting cylinder, which needs a 5-port AirTAC 4V valve.
