Airtac 3V100 Solenoid Valve 3V120M5B
The AirTAC Airtac 3V100 Solenoid Valve 3V120M5B is a genuine 3-port 2-position (3/2) solenoid valve with M5 ports. A 3/2 valve either feeds its outlet or vents it to exhaust, so it suits single-acting cylinders, air blow, clamping, vacuum switching and pilot duty. We stock this code and confirm its published figures from the datasheet on request.

About the Airtac 3V100 Solenoid Valve 3V120M5B
A 3/2 solenoid valve has three ports - supply, outlet, exhaust - and two positions. Energised one way it feeds air to the outlet; in the other state it shuts the outlet and vents the downstream line to exhaust. That feed-or-vent behaviour is exactly what a single-acting spring-return cylinder, an on/off air jet or a pilot line needs. The M5 port on this 3V120 variant is the smallest threaded connection in the family, so it belongs in compact circuits where a 1/8in fitting would be oversized.
It is a genuine AirTAC part: 3V120 body, M5 port, DC24V coil, DIN plug entry, PT thread as the family standard with G and NPT available to order. Across the 3V1/3V2/3V3 family the same function comes with normally closed or normally open states, five coil voltages, DIN or flying-lead entry, and 3V-F manifold bases. We publish no pressure, flow or coil-power figures on this page; send your application and we will read the datasheet values out for you.

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 3V100 Solenoid Valve 3V120M5B Is Used
Bottle-neck blow-off
Pulses a small air jet to clear dust from bottle necks ahead of capping on a packaging line.
Drill-jig clamp
Fills and vents a small single-acting swing clamp on a drilling jig, gripping and releasing under panel control.
Process valve piloting
Switches the pilot line of a larger pneumatic actuator on a water or air handling skid.
Is the Airtac 3V100 Solenoid Valve 3V120M5B the Right Part?
Tell us the state you want when ordering - the code carries no NC or NO marker. A normally closed valve keeps the outlet closed and vented until energised, so downstream air escapes on power loss; a normally open valve holds the outlet fed until switched. The M5 port is the smallest step in the family ladder of M5, 1/8in, 1/4in and 3/8in, matched to the smallest single-acting actuators and short blow lines. This coil is DC24V and must sit on a 24 volt DC panel; voltage is fixed per order code, not changeable by rewiring. Entry here is a DIN plug; add an I suffix for flying lead. Because no flow figures for this family are in our hands, ask us to confirm sizing against the actuator before ordering. If published figures are needed today, the AirTAC 3V2 (1/8in and 1/4in) and 3V3 (1/4in) bodies have published flow and coil-power data, and a double-acting cylinder calls for the AirTAC 4V series.
Confirm before you order
- ✓ Port size and thread (PT from stock; G / NPT to order)
- ✓ Initial state — NC or NO, ordered up front
- ✓ 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 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 3V100 Solenoid Valve 3V120M5B FAQ
This page publishes none, deliberately. We confirm operating pressure, flow and coil power from the AirTAC datasheet on request - send an RFQ with your actuator details. If you need published figures in front of you before you commit, the AirTAC 3V2 and 3V3 bodies carry published flow and coil-power data.
Decide by what must happen on power loss. NC blocks the outlet and vents downstream air when de-energised - the fail-safe choice where a clamp must release. NO keeps the outlet fed until switched. The code shown above carries neither marker, so state your preference on the RFQ.
