Airtac 3V2M Solenoid Valve 3V2MNOFI-19F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOFI-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 3V2MNOFI-19F
Nineteen normally open 3/2 stations on a single 3V2M base make the 3V2MNOFI-19F the densest assembly in this run: every coil at AC24V, every valve on a flying lead, one shared supply and one centralised exhaust path for the whole block. Rest state is flow - each outlet passes air until its solenoid is energised, then the spring return vents it, which is why NO manifolds are favoured on machines that must keep blowing, purging or releasing when control power drops.
Each valve is a direct-acting, single-solenoid coaxial shut-off (poppet) unit rated Cv 0.1 and IP65 (DIN 40050). Nineteen stations all energised draw 19 x 7 VA = 133 VA on the AC24V supply, so check your transformer margin before commissioning. Air must be filtered to 40 um or finer; lubrication is not required, and a manual override on each body speeds 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 3V2MNOFI-19F Is Used
Food tray washer air knives
Nineteen NO valves feed the air knife array of a tray washer, so knives keep blowing even during a control outage, with all exhausts collected at one silenced point.
Machine tool chip-blow manifold
A CNC line's chip-clearing jets sit on one 19-way base; each zone blows by default and is vented on command, keeping setup and tuning to single connections.
Press guard pin release bank
Safety interlock pins on a stamping press stay engaged on stored air via normally open stations; energising a station vents and releases it, one base wiring run for all nineteen.
Is the Airtac 3V2M Solenoid Valve 3V2MNOFI-19F the Right Part?
Order the 19F assembly when nineteen fail-flow (NO) circuits share an AC24V control system and lead-out wiring is preferred to DIN sockets. Settle the five-order points first - initial state (NO, unchangeable after purchase), voltage (AC24V), entry (flying lead), stations (19) and exhaust (centralised here; choose a -D code if each station must vent separately). Thread is PT as the family standard, with G and NPT available to order.
When a particular station needs more than Cv 0.1, split the duty: keep the manifold for the low-flow points and put an individually ported 3V2 (Cv 0.18 at 1/8 in, 0.19 at 1/4 in, vacuum-rated) or a 3V3 (Cv 0.62, 1/4 in, vacuum-rated) on the heavy line. If the whole duty is light, 3V1 at 3.0 W DC cuts coil draw. Double-acting cylinders fall outside any 3/2 valve - use the AirTAC 4V series.
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 3V2MNOFI-19F FAQ
Nineteen 3/2 normally open valves, direct-acting, single solenoid, spring return, one base, flying leads, AC24V. Cv 0.1 per station, pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, coil power 7 VA AC (7.0 W DC types), IP65 (DIN 40050), PT1/8 ports, 40 um filtration, lubrication not needed, manual override fitted. 3V2M has no vacuum rating in the catalogue.
With no D suffix, all nineteen stations exhaust through the base's common path - one silencer, simpler pipework, but stations are not individually vented; order a -D code if you need separate exhausts. Normally open means flow continues when a coil is de-energised, chosen for fail-flow duties. The state is fixed at manufacture: reversing the 3V2M base gasket does not convert NO to NC, so order the correct state. These valves drive single-acting cylinders only; double-acting needs an AirTAC 4V 5-port valve.
