Airtac 3V1 Solenoid Valve 3V106CI
The AirTAC Airtac 3V1 Solenoid Valve 3V106CI 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 3V106CI
3V106CI is an AirTAC 3V1 body solenoid valve in the 1/8in port size, fitted with an AC110V coil drawing 4.5 VA and supplied with pre-wired flying leads instead of a DIN socket. As a direct-acting 3/2-way valve it switches a single line between feed and exhaust: one state supplies the outlet, the other vents it, and the spring return gives a defined de-energised position without a second coil.
That single-line switching suits spring-return cylinders, clamps, on-off air blow and pilot duty on larger process valves. The 4.5 VA coil keeps control-cabinet load low, and the lead-out wiring speeds connection where a plug-in connector is awkward. A manual override is fitted to help set-up and 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 3V106CI Is Used
Ejector on a blister packer
Feeds and vents a small single-acting eject cylinder on a pharmaceutical blister packing line, with the AC110V coil wired straight into the machine control panel.
Pilot stage on a bottling line
Supplies a pilot signal to a larger pneumatic process valve controlling rinse flow, with the spring return venting the pilot line whenever power is lost.
Blow-off over a filling head
Switches a short blast of shop air that clears dust from a filling nozzle between cycles, at the low 4.5 VA draw an AC110V control circuit expects.
Is the Airtac 3V1 Solenoid Valve 3V106CI the Right Part?
Start from the port and the duty. 3V1 is the smallest, lowest-power body in the AirTAC 3V range, but no Cv is published for it, so if your duty is flow-critical, confirm sizing with us before ordering. When more flow is needed, 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); 3V2M is the better pick when dense manifold mounting matters more than flow.
Before you buy 3V106CI, match five points: 1/8in port with PT thread (G or NPT are catalogue options to order), the AC110V coil, the flying-lead entry, and whether you want this individual valve or a 1F-20F manifold assembly. If you must drive a double-acting cylinder, move to the AirTAC 4V series.
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 3V106CI FAQ
It is a direct-acting, single-solenoid, spring-return 3/2 valve in a PT1/8in port size. Operating pressure is 0-0.8 MPa (0-114 psi), medium temperature -20 to 70 C, protection IP65 to DIN 40050. The AC110V coil draws 4.5 VA and the connection is a flying lead. Air must be filtered to 40 um or finer. No flow coefficient (Cv) or effective area is published for the 3V1 body - ask us to confirm flow data if it matters to your duty.
Yes for single-acting, spring-return cylinders, clamps, air blow and pilot duty - a 3/2 valve either feeds the outlet or vents it. It cannot drive a double-acting cylinder, which needs simultaneous feed and exhaust paths; use the AirTAC 4V series there. Note also that the 3V1 range carries no published vacuum rating, so do not specify it for negative-pressure work.
