Airtac 3V1 Solenoid Valve 3V1M5BI1F
The AirTAC Airtac 3V1 Solenoid Valve 3V1M5BI1F 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 3V1M5BI1F
The 3V1M5BI1F is a one-station 3V1 assembly: a 3/2 direct-acting solenoid valve with DC24V coil, flying-lead entry and M5 porting, pre-mounted on its single-station base. It either feeds the outlet or vents it to exhaust, which is exactly what a spring-return single-acting cylinder, a blow-off nozzle or a pilot stage needs.
Because the valve is direct acting with a spring return, it shifts on coil power alone and snaps back when power drops. The DC24V coil draws just 3.0 W, so it runs cool on switched 24 V supplies, and the lead-out wires let you land the connections directly on your terminal strip instead of plugging in a DIN connector.

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 3V1M5BI1F Is Used
Blow-off on a compact filling line
A puff of valve-fed air clears dust or droplets from bottle necks before capping; the spring return vents the nozzle circuit the instant the coil drops out.
Pneumatic clamp on a drill jig
One station feeds the clamp cylinder to hold the workpiece and vents it on release, so the jig cannot stay clamped after a power cut.
Pilot stage for a large process valve
The M5 valve meters the pilot signal that strokes a bigger diaphragm or cylinder-operated valve mounted on a process skid.
Is the Airtac 3V1 Solenoid Valve 3V1M5BI1F the Right Part?
3V1 is the smallest, lowest-power body in AirTAC's 3V range, and this code fixes the configuration: M5 port, DC24V coil, flying-lead entry, single-station base. AirTAC publishes no Cv for 3V1, so if your duty is flow-critical, size upward instead: the 3V2 covers 1/8 and 1/4 ports, is NC or NO selectable, is rated for vacuum and offers Cv 0.18-0.19, while the 3V3 gives 1/4 porting at Cv 0.62. Choose 3V2M when manifold density matters more than flow. If you need to drive a double-acting cylinder, move to the AirTAC 4V series - a 3/2 valve cannot do it.
Before ordering, confirm five points: M5 vs 1/8 port, thread on 1/8 codes (PT is standard; G and NPT are order options), coil voltage, DIN plug vs flying lead, and whether you need an individual valve or a manifold station count. Air is assumed filtered to 40 um or finer; lubrication is not 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 Blank any unused station on the base before pressurising.
- check Wiring by qualified personnel, per AirTAC documentation.
Airtac 3V1 Solenoid Valve 3V1M5BI1F FAQ
Operating pressure 0-0.8 MPa (0-114 psi); medium temperature -20 to 70 C; DC24V coil rated 3.0 W; protection class IP65 to DIN 40050; air filtered to 40 um or finer, with no lubrication needed. AirTAC publishes no Cv or effective area for the 3V1 body - ask us if flow matters.
One station either feeds or vents a single line, so it suits spring-return single-acting cylinders, clamps, air blow and pilot duty. It cannot reverse a double-acting cylinder - that needs a 5-port valve such as AirTAC's 4V series.
