Airtac 3V1 Solenoid Valve 3V106B2F
The AirTAC Airtac 3V1 Solenoid Valve 3V106B2F 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 3V106B2F
Two circuits, one small base: the AirTAC 3V106B2F mounts a pair of 3/2 direct-acting solenoid valves side by side, each independently wired and independently sprung. A 3/2 valve controls a single line - supply it, or dump it to exhaust - so this pair suits matched single-acting cylinders, a clamp plus a blow nozzle, or two separate pilot signals.
Both coils run on DC24V at 3.0 W with IP65 (DIN 40050) protection, and each valve carries a manual override for commissioning. The 1/8in ports use the PT thread that is this family's standard.

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 3V106B2F Is Used
Conveyor stopper gate
Raises and lowers a spring-return stopper that pauses cartons at a merge point, the spring return dropping the gate whenever coil power is lost.
Welding fixture clamp pair
Operates the hold-down and the part-ejector cylinders of a welding jig as two independent 3/2 circuits on one base, one valve per function.
Filling-head air wipe
Trims a precise puff of air to clean a filling nozzle between doses, with the manual override handy while dialling in the rinse cycle.
Is the Airtac 3V1 Solenoid Valve 3V106B2F the Right Part?
Use the 3V106B2F when two valves belong together but four would be too many - the base accepts further stations, and 1F to 20F are all catalogue codes. Because AirTAC publishes no Cv for 3V1, confirm flow-sensitive duties with us. Circuits demanding more flow step up to 3V2 (1/8in and 1/4in, NC or NO selectable, Cv 0.18-0.19, vacuum rated) or 3V3 (1/4in, Cv 0.62), while 3V2M trades flow for manifold density. A double-acting cylinder requires the 5-port AirTAC 4V series.
Confirm five things before ordering: port (M5 or 1/8in), thread (PT standard, G or NPT to order), coil voltage, entry style (DIN plug or flying lead), and valve count per base.
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 3V106B2F FAQ
Pressure 0-0.8 MPa (0-114 psi); temperature -20 to 70 C; air filtered through a 40 um or finer element. Each of the two DC24V coils takes 3.0 W and is protected to IP65 (DIN 40050). The valve is a direct-acting 3/2 with spring return. AirTAC states no Cv for the 3V1 body, so verify flow duty with our team.
The spring return takes each spool to its single fixed initial state - confirm exactly which state that is on the datasheet before wiring the interlock. A manual override on each valve lets you cycle the pair by hand during set-up. Do not use it on a double-acting cylinder; that is a job for the AirTAC 4V series.
