Airtac 3V1 Solenoid Valve 3V106A7F
The AirTAC Airtac 3V1 Solenoid Valve 3V106A7F 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 3V106A7F
Seven 3/2 direct-acting valves share one base in the AirTAC 3V106A7F assembly, so a seven-circuit panel needs a fraction of the tubing, fittings and drilling of seven loose bodies. Every valve is a 1/8in PT, single-solenoid, spring-return unit: it either feeds its outlet or vents it, which suits single-acting cylinders, clamps, air blow and pilot duty.
Each AC220V coil takes 4.5 VA and meets IP65 (DIN 40050), and the DIN plug connection lets you unplug one station without disturbing the others. Manual overrides are fitted to help set-up and commissioning. Filter the air supply to 40 um or finer - no lubricator is needed. Supplied as genuine AirTAC product.

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 3V106A7F Is Used
Pilot stage on process valves
Pilots the actuator of a larger pneumatic knife-gate valve on a water-treatment skid, one 3V1 station per main valve.
Bottling line filler block
Controls the fill-head clamp and purge circuits on a rotary bottling filler, seven circuits on one drilled manifold instead of seven loose bodies.
PCB wash blow-off
Runs intermittent air-blow nozzles that dry circuit boards after a wash stage, with each nozzle vented to exhaust while idle.
Is the Airtac 3V1 Solenoid Valve 3V106A7F the Right Part?
Because AirTAC publishes no flow coefficient for the 3V1 body, treat it as a small-port control valve and confirm duty-critical flow with us. When you need more, 3V2 offers 1/8in and 1/4in ports, a choice of NC or NO function, Cv 0.18-0.19 and a vacuum rating, while 3V3 gives a 1/4in port at Cv 0.62. For tight manifold layouts where flow is secondary, compare 3V2M. Never put 3V1 on a double-acting cylinder - that needs the 5-port AirTAC 4V series.
Before ordering, confirm the port (M5 or 1/8in), the thread (PT standard, with G or NPT as order options), the coil voltage, DIN plug versus flying lead, and how many stations your manifold requires.
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 3V106A7F FAQ
Pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, IP65 protection (DIN 40050), and a 3/2 direct-acting spring-return function. Coil power depends on voltage: AC220V 4.5 VA, AC110V 4.5 VA, AC24V 5.0 VA, DC24V 3.0 W, DC12V 2.5 W. No Cv or effective area is published for 3V1; verify flow-critical applications with us.
Each three-port, two-state valve feeds or exhausts one line, so it cycles single-acting spring-return cylinders, clamps and punchers, runs intermittent air blow, or pilots a larger main valve. It cannot reverse a double-acting cylinder, which needs both a pressure and an exhaust path - use the AirTAC 4V series there.
