Airtac 3V1 Solenoid Valve 3V106B
The AirTAC Airtac 3V1 Solenoid Valve 3V106B 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.
- Valve type3/2-way (3-port, 2-position)
- Port size1/8 in
- Coil voltageDC24V
- Electrical entryDIN plug (DIN socket type)
- Series3V1
About the Airtac 3V1 Solenoid Valve 3V106B
The 3V106B is the individual single-valve version of the 3V1: one 3/2 body in PT1/8 that either feeds a line or vents it, under the control of a single DC24V solenoid and a return spring. Fit it wherever a small single-acting cylinder, clamp, nozzle or pilot line needs simple on/off air logic.
The DC24V coil is the efficiency story here: 3.0 W is the lowest standard draw in the 3V1 family, kind to compact power supplies, and it still meets IP65 (DIN 40050). The DIN plug entry lets you unplug the coil for service, and the fitted manual override helps during installation. Ask us for a quote on this genuine AirTAC valve.

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 3V106B Is Used
Single-acting cylinder on a bench press
A small spring-return press cylinder needs feed-and-vent control only, exactly what this 3/2 valve delivers from a 3.0 W DC24V coil.
Label blow-off on a canning line
Energise to blast dust off a can label, de-energise and the spring vents the nozzle line - one DIN-plug coil, no separate pilot circuit needed.
Analyser cabinet purge
Periodic positive-air purge of a gas-analyser enclosure can be timed from a PLC output driving this low-power 24 V coil.
Is the Airtac 3V1 Solenoid Valve 3V106B the Right Part?
The 3V106B is the lowest-power entry point of the 3V range: 3.0 W at DC24V keeps the power supply small. Its flow capacity is not characterised by a published Cv, so for flow-critical duties ask us, or move 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). The 3V2M is the alternative when manifold density outranks flow.
Match five things to your panel: M5 or 1/8in port, PT (standard) or G/NPT thread to order, coil voltage - AC220V, AC110V, AC24V, DC24V or DC12V - DIN plug versus flying-lead entry, and individual valve or manifold. A double-acting cylinder needs a 5-port valve, so specify the AirTAC 4V series for that job.
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 Wiring by qualified personnel, per AirTAC documentation.
Airtac 3V1 Solenoid Valve 3V106B FAQ
Pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, medium air filtered through a 40 um or finer element. The DC24V coil takes 3.0 W (other voltages in the family: AC220V and AC110V 4.5 VA, AC24V 5.0 VA, DC12V 2.5 W) and is rated IP65 (DIN 40050). No Cv or effective area is published for 3V1 - ask us before sizing by flow.
Three ports and two states mean it either feeds the outlet or vents it, which suits single-acting spring-return cylinders, blow-off nozzles, clamps and pilot signals. It cannot run a double-acting cylinder, which needs two lines - that is the job of a 5-port AirTAC 4V valve.
