Airtac 3V1 Solenoid Valve 3V106BI2F
The AirTAC Airtac 3V1 Solenoid Valve 3V106BI2F 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 3V106BI2F
The 3V106BI2F puts two independently switched 3/2 stations on one small manifold fed by a single air connection - a neat way to handle paired actions such as clamp plus eject, or feed plus vent, without plumbing two separate valves. Both positions are direct-acting with a single solenoid and spring return: the outlet is either pressurised or exhausted.
This SKU pairs the DC24V coil (3.0 W, the lowest draw in the 3V1 range) with flying-lead wiring, so the coils connect to your terminals without a DIN plug. Coils are protected to IP65 (DIN 40050), the supplied initial state is fixed - confirm it on the datasheet - and each station has a manual override so you can prove the plumbing before energising anything.

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 3V106BI2F Is Used
Drill-jig clamp and chip blow
A small drilling jig first clamps the workpiece, then a blow nozzle clears swarf from the hole; the two 3/2 stations alternate between clamping and blow-off on the cycle.
CNC fixture part-present vent
A CNC fixture holds a part with one spring-return clamp while a second station vents the part-present sensing line when the door opens, both run from the same manifold feed.
Depositor twin gates on a bakery line
A dough depositor opens its hopper gate and, on the same island, a second station switches a small cutter cylinder, giving two synchronised actions from one air inlet.
Is the Airtac 3V1 Solenoid Valve 3V106BI2F the Right Part?
Sizing starts from an honest gap: 3V1 carries no published Cv or effective-area value, so for paired outputs where flow matters, let us check the duty against 3V2 (1/8in and 1/4in ports, NC or NO selectable, Cv 0.18-0.19, vacuum-rated) or 3V3 (1/4in, Cv 0.62). Where the goal is a tight island rather than flow, 3V2M is the purpose-built alternative. Confirm five things before you order: the 1/8in port in PT (G or NPT available as order options), the DC24V voltage, flying-lead entry, the 2F two-station assembly, and air filtered to 40 um or finer with no lubrication. To reverse a double-acting cylinder you need 5 ports - the AirTAC 4V series covers 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 Blank any unused station on the base before pressurising.
- check Wiring by qualified personnel, per AirTAC documentation.
Airtac 3V1 Solenoid Valve 3V106BI2F FAQ
Working pressure 0-0.8 MPa (0-114 psi); temperature -20 to 70 C; IP65 (DIN 40050) coil protection; DC24V coils at 3.0 W each. For reference across 3V1: AC220V 4.5 VA, AC110V 4.5 VA, AC24V 5.0 VA, DC12V 2.5 W. AirTAC does not publish a Cv or effective area for 3V1, so check flow-critical duties with us.
The two stations share one manifold air inlet, one mounting and much of the plumbing, while each keeps its own flying-lead DC24V coil and switches independently. Ports are PT1/8 on this family; G and NPT threads exist as catalogue options to order.
