AirTAC 3V106B-20 Solenoid Valve, 3V1 Series (3V106B20F)
The AirTAC AirTAC 3V106B-20 Solenoid Valve, 3V1 Series (3V106B20F) 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 3V106B-20 Solenoid Valve, 3V1 Series (3V106B20F)
Twenty valves, one footprint: the AirTAC 3V106B20F stacks twenty 3/2 direct-acting solenoid valves in series on a shared base, so a panel that once held a scatter of individual bodies becomes one ordered bank. Each valve feeds or vents its own line with a single solenoid and spring return.
Power stays modest because every DC24V coil needs just 3.0 W, and each is sealed to IP65 (DIN 40050) against dust and splashing water. Ports are 1/8in, threaded PT as standard for this series.

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 3V106B-20 Solenoid Valve, 3V1 Series (3V106B20F) Is Used
Mold core-pull bank
Runs twenty independent core-pull or ejector circuits on an injection mold tool from one shared base, keeping the tool's valve plate compact and orderly.
Bottling line clamp bank
Sequences bottle clamping and release points along a filling line, each 3/2 valve feeding or venting its own single-acting clamp in step with the conveyor.
Diagnostics analyzer deck
Drives the small pneumatic actuator rows of an automated sample-handling deck, where 3.0 W DC24V coils keep the analyzer's 24 V rail load light.
Is the AirTAC 3V106B-20 Solenoid Valve, 3V1 Series (3V106B20F) the Right Part?
Design a 20-station bank around the control panel, not around flow: the 3V1 body is the smallest in the range, its Cv is unpublished, and any flow-critical branch should be checked with us first. Branches that need more air take a 3V2 (1/8in or 1/4in, NC or NO selectable, Cv 0.18-0.19, vacuum rated) or a 3V3 (1/4in, Cv 0.62); 3V2M serves when dense manifolding outranks flow. Double-acting cylinders call for the 5-port AirTAC 4V family.
Lock the order down on five checks: M5 or 1/8in port, thread (PT standard, G or NPT to order), DC24V coil, DIN plug entry, and the station count from 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 3V106B-20 Solenoid Valve, 3V1 Series (3V106B20F) FAQ
Each valve handles 0-0.8 MPa (0-114 psi) at -20 to 70 C on air filtered to 40 um or better. Coils are DC24V at 3.0 W with IP65 (DIN 40050) housings, and there are twenty of them on the shared base. Function is direct-acting 3/2, single solenoid, spring return. No Cv or effective area is published for 3V1 - confirm flow needs with us.
Every coil in the bank is DC24V and rated 3.0 W, so twenty valves present twenty 3 W loads to your 24 V supply - check the supply margin against the datasheet before energising the whole manifold. DIN plug entry lets you wire, test and replace each valve individually.
