Airtac 3V1 Solenoid Valve 3V106B-NT
The AirTAC Airtac 3V1 Solenoid Valve 3V106B-NT 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 3V106B-NT
The 3V106B-NT is a 3/2-way, direct-acting solenoid valve with a 1/8in NPT port - the American taper thread you order explicitly on this family, whose standard is PT. One coil feeds the outlet with air or vents it to exhaust, and a spring returns the valve the instant power drops, so it suits single-acting cylinders, air blow, clamping and pilot duty.
Its DC24V coil draws just 3.0 W, easy on PLC output cards, and the body is sealed to IP65 (DIN 40050). A manual override is fitted to help with setup and fault-finding. This is genuine AirTAC, quoted through AirtacDistr.

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-NT Is Used
Carton eject gate
Venting a single-acting air cylinder that kicks misprinted cartons off a food packaging conveyor the moment the coil drops out.
Fixture clamp
Feeding a spring-return swing clamp on a CNC drilling jig, with the exhaust port releasing clamp pressure automatically.
Pilot signal duty
Sending a pilot signal to a larger pneumatic process valve on a small water dosing skid, switched from a 24 V panel.
Is the Airtac 3V1 Solenoid Valve 3V106B-NT the Right Part?
The 3V1 is the smallest, lowest-power body in AirTAC's 3V range and publishes no Cv, so if flow decides the job, tell us the duty and we will check it against the 3V2 (1/8in and 1/4in, NC or NO selectable, Cv 0.18-0.19, and rated for vacuum) or the 3V3 (1/4in, Cv 0.62). Where a dense manifold beats raw flow, look at 3V2M. If your actuator is double-acting, that needs a 5-port valve - go to the AirTAC 4V series.
Before ordering this NPT version, match five points: port size (M5 or 1/8in), thread (PT is the family standard; this code carries NPT, and G is also a catalogue option), coil voltage, electrical entry (DIN plug or flying lead), and individual valve versus manifold station count.
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-NT FAQ
AirTAC rates this 3/2 valve for 0-0.8 MPa (0-114 psi) and -20 to 70 C, with IP65 (DIN 40050) protection. On DC24V the coil draws 3.0 W; across the family, AC220V and AC110V coils take 4.5 VA, AC24V takes 5.0 VA and DC12V takes 2.5 W. No Cv or effective-area figure is published for 3V1 - ask us to confirm flow against your duty.
It feeds or vents one line, so it is meant for single-acting spring-return cylinders, on/off air blow, clamping, and piloting a larger valve. It cannot run a double-acting cylinder - that needs a 5-port valve such as the AirTAC 4V series.
