Airtac 3V100 Solenoid Valve 3V120M5BI
The AirTAC Airtac 3V100 Solenoid Valve 3V120M5BI 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 3V120M5BI
The I at the end of 3V120M5BI means the coil arrives as a flying lead: pre-wired tails you land directly on your terminals, instead of seating a DIN plug onto a socket. Functionally it is the same 3/2 valve: three ports, two positions, one state feeding the outlet and the other venting it to exhaust. With an M5 port it is the compact option of the family for small single-acting cylinders and short blow lines.
Genuine AirTAC, 3V120 body, DC24V coil, PT thread as standard with G and NPT available to order. The family also runs normally closed and normally open states, AC220V, AC110V, AC24V and DC12V coils alongside this DC24V one, DIN plug entry, and 3V-F manifold bases for multi-valve assemblies. Datasheet figures for pressure, flow and coil power are not on this page - ask and we will pull them together for your review.

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 3V120M5BI Is Used
Fixture part ejection
Feeds a compact spring-return cylinder that pushes a finished part out of a machining fixture.
Bench-top sample handling
Actuates a miniature air cylinder that indexes sample trays on an automated laboratory bench.
Spray head selection
Directs air to a small actuator that swings a spray head into position on a coating bench.
Is the Airtac 3V100 Solenoid Valve 3V120M5BI the Right Part?
Start with the wiring decision, because it is fixed at order time: this flying-lead version arrives pre-terminated for your terminals, while the non-I code takes a DIN plug on a socket. The coil is DC24V and must be fed 24 volts DC; coil voltage cannot be converted by rewiring. Next, tell us the state you need - the code carries no NC or NO marker - remembering that NC removes air from the outlet and vents it on power loss while NO keeps the outlet fed until switched. The M5 port is the smallest in a ladder that runs M5, 1/8in, 1/4in and 3/8in, so step up a size for a bigger single-acting actuator. Flow data for this family are not published by us, so ask us to check sizing against your actuator before ordering; the documented AirTAC 3V2 and 3V3 bodies carry published flow and coil-power figures if you need them on the page, and a double-acting cylinder belongs on 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 3V120M5BI FAQ
Not printed here - we hold no specification sheet for this family and will not guess numbers. Request them by RFQ and we will confirm every figure from the datasheet before you order. Buyers who need published performance immediately are pointed to the AirTAC 3V2 (1/8in and 1/4in) and 3V3 (1/4in) bodies, where flow and coil power are documented.
No. A 3/2 valve has one outlet, so it can fill and vent a single-acting, spring-return actuator but cannot push and pull a double-acting one, which needs two outlet connections. For that job use an AirTAC 4V 5-port valve. The 3V120M5BI suits single-acting clamps, air jets and pilot duty.
