Airtac 3V1 Solenoid Valve 3V1M5BI5F
The AirTAC Airtac 3V1 Solenoid Valve 3V1M5BI5F 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 3V1M5BI5F
The 3V1M5BI5F is the densest assembly in this M5 flying-lead set: five 3/2 spring-return valves sharing one base. Energise a coil to feed its outlet; cut power and the spring vents the line, making each station a natural on/off for single-acting cylinders, clamps, air jets or pilot signals.
Five stations on one base replace five separate valves, their fittings and their individual wiring runs. Every DC24V coil draws just 3.0 W and carries an IP65 (DIN 40050) rating, and the manual override on each valve lets you jog every function during 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 3V1 Solenoid Valve 3V1M5BI5F Is Used
Fixture bank on a small machining cell
Five clamping points on one fixture plate each get their own spring-return valve, so a single base and one air supply serve the whole clamping bank.
Multi-circuit pilot panel on a water-treatment skid
Each station meters a pilot signal to a larger actuated process valve, letting one compact panel sequence several treatment lines in turn.
Clamps and blow nozzles at a repair workshop bench
Retractable jigs, part-blow jets and chip-clearing nozzles around the bench all hang off one five-station M5 manifold, jogged via the manual overrides.
Is the Airtac 3V1 Solenoid Valve 3V1M5BI5F the Right Part?
Five M5 stations on one base is about as dense as low-power 3/2 control gets, but 3V1 is a small-port body and its flow coefficient is not published by AirTAC. For duties where flow rules, compare the 3V2 (1/8 or 1/4 port, NC/NO selectable, Cv 0.18-0.19, vacuum capable) and the 3V3 (1/4 port, Cv 0.62); where packing many functions into a small cabinet is the goal, 3V2M exists for exactly that. A 3/2 valve can never reverse a double-acting cylinder - specify the 4V series there.
Because this code spells out M5 port, DC24V coil, flying lead and a 5-station base, only two choices remain open: whether M5 is truly the port you want (1/8 versions come as PT, with G and NPT as order options) and whether five stations is the right count for your fixture bank.
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 Blank any unused station on the base before pressurising.
- check Wiring by qualified personnel, per AirTAC documentation.
Airtac 3V1 Solenoid Valve 3V1M5BI5F FAQ
Five 3/2 stations on one base; operating pressure 0-0.8 MPa (0-114 psi); temperature -20 to 70 C; five DC24V coils at 3.0 W each, 15.0 W total; IP65 per DIN 40050; air filtered to 40 um or better. AirTAC publishes no Cv or effective area for 3V1 - request it from us if flow is critical.
Each valve is direct acting with a spring return: energise the DC24V coil to feed the outlet, cut power and the spring vents the line. The catalogue supplies 3V1 in a single fixed initial state - confirm it on the datasheet - and a manual override on each station lets you test every function before wiring is finished.
