Airtac 3V1 Solenoid Valve 3V1M5AI3F
The AirTAC Airtac 3V1 Solenoid Valve 3V1M5AI3F 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 3V1M5AI3F
The 3V1M5AI3F is a ready-built 3-station block: three M5 direct-acting 3/2 valves sharing one manifold base, each a spring-return solenoid that feeds or vents its own outlet line. Each valve comes in one fixed initial state; check the datasheet to confirm it.
Every AC220V coil draws just 4.5 VA, so the whole block stays well inside modest power budgets, and the flying-lead entry means the three coils can be wired onto one loom. The integrated base saves the panel space of three separate bodies, and each station keeps its manual override so a technician can jog one output without energising the others. Air must be filtered to 40 um or finer.

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 3V1M5AI3F Is Used
Modular fixture plate functions
On a modular tooling plate, the block drives clamp, blow-off and eject signals - one valve per function on a shared M5 base, wired together on a single flying-lead loom.
Lab bench pilot rig
A university test rig sequences three small pilot lines independently, with the 4.5 VA AC220V coils switched one at a time and each station jogged by hand during trials.
Bottling skid gate control
On a small bottling skid the block feeds and vents three short actuator lines for gate, stopper and counter, all dropping to exhaust together whenever control power fails.
Is the Airtac 3V1 Solenoid Valve 3V1M5AI3F the Right Part?
For three outlets on one base, this block beats plumbing three individual bodies. Remember that 3V1 has no published Cv; if flow matters, move up to 3V2 (Cv 0.18-0.19, NC or NO selectable, vacuum rated) or 3V3 (1/4 port, Cv 0.62), or pick 3V2M where manifold density outranks flow. Double-acting cylinders belong to the 5-port 4V family, not here.
Five checks before you commit: port size (M5 or 1/8), thread on 1/8 variants (PT standard; G or NPT as catalogue options to order), coil voltage, entry style (this code is flying lead; DIN plug is the alternative), and station count (this code is 3F, a 3-station assembly - the family runs 1F to 20F).
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 3V1M5AI3F FAQ
Operating pressure 0-0.8 MPa (0-114 psi); temperature -20 to 70 C; each AC220V coil 4.5 VA (the 3V1 range also offers AC110V at 4.5 VA, AC24V 5.0 VA, DC24V 3.0 W and DC12V 2.5 W); IP65 (DIN 40050); air filtered through 40 um or finer; 3/2 direct-acting, spring return, manual override. AirTAC publishes no Cv or effective area for 3V1, so verify flow before final sizing.
Yes - the 3V1 manifold family runs from 1F to 20F in series, so a 5F, 8F or larger block shares the same M5 valves and AC220V flying-lead coils. This code is the 3-station version, and maintenance parts include the 3V1-P30 connecting-screw base set and the 3V1-P31 O-ring and long screw kit.
