Airtac 3V1 Solenoid Valve 3V1M5FI
The AirTAC Airtac 3V1 Solenoid Valve 3V1M5FI is a genuine 3-port 2-position (3/2) solenoid valve with M5 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 3V1 Solenoid Valve 3V1M5FI
The 3V1M5FI is a direct-acting 3/2-way solenoid valve with one coil and a spring return: in one state it feeds the outlet from supply, in the other it dumps that same line to exhaust. That feed-or-vent action is what drives single-acting spring-return cylinders, air-blow nozzles, clamping jaws and pilot stages - it is not a valve for double-acting cylinders. Being direct-acting, it shifts with no minimum supply pressure, and it is supplied in a single fixed initial state - confirm it on the datasheet before wiring safety logic.
This exact SKU pairs an M5 port with a DC12V coil drawing just 2.5 W, the lowest draw in the 3V1 line-up, and comes as the flying-lead version, so the coil connects through pre-fitted lead-out wires rather than a DIN socket. Coil protection is IP65 (DIN 40050), and a manual override on the body helps during installation and commissioning. AirtacDistr supplies this valve as genuine AirTAC product with datasheets on request.

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 3V1 Solenoid Valve 3V1M5FI Is Used
Lab sample gripper
Actuates the spring-return mini cylinder on a benchtop sample-handling gripper, where the 2.5 W DC12V coil suits a low-power 12 V control supply.
Solder-joint blow-off
Pulses a small nozzle that clears flux dust off PCBs after reflow; the M5 port keeps tubing runs and footprint minimal at each station.
Service-truck clamp
Opens and closes a spring-return clamp on a battery-fed service vehicle, with the flying lead wired straight to the 12 V distribution block.
Is the Airtac 3V1 Solenoid Valve 3V1M5FI the Right Part?
3V1 is the smallest and lowest-power body in the 3V range, and its flow coefficient is not published, so any flow-critical duty should be confirmed with us first. When M5 flow is not enough, step up to the 3V2 series (1/8in and 1/4in ports, NC or NO selectable, Cv 0.18-0.19, and rated for vacuum) or the 3V3 (1/4in, Cv 0.62); choose 3V2M where a dense manifold matters more than flow. If your actuator is double-acting, move to the AirTAC 4V series of 5-port valves.
Before ordering, match five points: port (M5 or 1/8in); thread - on the 1/8in versions of this family PT is the standard thread and G or NPT are catalogue options to order, though an M5 body like this one carries no separate thread code at all; coil voltage; electrical entry (DIN plug or flying lead); and whether you need one valve or a manifolded station count. The medium must be air filtered to 40 um or finer, with no lubrication required.
Confirm before you order
- ✓ Port size and thread (PT from stock; G / NPT to order)
- ✓ 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 Wiring by qualified personnel, per AirTAC documentation.
Airtac 3V1 Solenoid Valve 3V1M5FI FAQ
Pressure range 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, protection IP65 (DIN 40050), and coil power of 2.5 W at this SKU's DC12V (other catalogue options: AC220V 4.5 VA, AC110V 4.5 VA, AC24V 5.0 VA, DC24V 3.0 W). AirTAC does not publish a Cv or effective area for the 3V1 series, so confirm flow-critical sizing from the datasheet.
Anything that needs one line fed and vented: single-acting spring-return cylinders, clamps, on/off air-blow jets, or a pilot signal for a larger main valve. It will not operate a double-acting cylinder - that requires two outlet lines and a 5-port valve such as the AirTAC 4V series.
