Airtac 3V1 Solenoid Valve 3V106BI20F
The AirTAC Airtac 3V1 Solenoid Valve 3V106BI20F 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 3V1 Solenoid Valve 3V106BI20F
3V106BI20F is the largest island in the 3V1 family: twenty 3/2 valve positions integrated in series on one manifold, replacing twenty separate bodies, their fittings and the panel drilling that goes with them. Each position is direct-acting with a single solenoid and a spring return, so it alternates its outlet between supply and exhaust - the pattern that single-acting cylinders, clamps, blow nozzles and pilot stages follow.
Twenty DC24V coils at 3.0 W each keep total holding power low, which matters when the island sits inside a control cabinet fed from a small 24 V supply. Wiring is by lead-out wires rather than DIN sockets, each coil housing meets IP65 (DIN 40050), and every station carries a manual override for 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 3V106BI20F Is Used
ICT fixture with twenty clamp points
An in-circuit test fixture closes twenty spring-return clamps around a PCB; each clamp line gets its own 3/2 station on the island, so the fixture is wired and serviced from one manifold.
Parcel sorter gate bank
A distribution-centre sorter diverts parcels across many chutes; groups of gate cylinders are driven station by station, and a failed gate is isolated and swapped on the shared island.
Turret screwdriver feed and vent
An automatic screwdriving turret powers its part-present sensor jet and small hold-down clamps from one island, switching each line between feed and exhaust within the cycle.
Is the Airtac 3V1 Solenoid Valve 3V106BI20F the Right Part?
Flow is the one figure this island cannot promise: AirTAC states no Cv or effective-area value for 3V1, so a 20-station bank on a flow-sensitive duty deserves a sizing check with us first. Should any circuit need more air, the upgrade path runs to 3V2 (1/8in and 1/4in, selectable NC or NO, Cv 0.18-0.19, vacuum-rated) or 3V3 (1/4in, Cv 0.62); if island compactness outranks flow, compare 3V2M. Specifying is a five-point exercise: 1/8in PT port (G or NPT as threads to order), DC24V coil, flying-lead entry, 20F station count, and 40 um-or-finer filtration with no lubrication. Double-acting actuators stay out of scope for a 3-port valve - the AirTAC 4V series is built for them.
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 3V106BI20F FAQ
Every station shares the 3V1 ratings: 0-0.8 MPa (0-114 psi) working pressure, -20 to 70 C temperature, IP65 (DIN 40050) coil protection. The DC24V coil draws 3.0 W; elsewhere in the family AC220V and AC110V coils take 4.5 VA, AC24V 5.0 VA and DC12V 2.5 W. No Cv or effective-area figure is published for 3V1, so confirm flow with us before sizing critical circuits.
One manifold air supply, one set of connections and one mounting footprint replace twenty individual bodies and their fittings, which is the main way this family saves panel space. Each of the twenty stations still switches independently on its own flying-lead DC24V coil, and manual overrides let you exercise any output during setup.
