Airtac 3V100 Solenoid Valve 3V120-M5-A
The AirTAC Airtac 3V100 Solenoid Valve 3V120-M5-A 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 3V120-M5-A
The AirTAC 3V120-M5-A is a genuine 3/2 solenoid valve on the 3V120 body: three ports - supply, outlet, exhaust - and two positions, so it either feeds the outlet or vents it to exhaust. The M5 thread is the smallest port in this family, aimed at compact single-acting cylinders, needle jets and pilot lines. The coil is AC220V with a DIN plug entry, so installation is a plug-in connection to your 220V AC control circuit. The code does not spell out a rest state, so we do not claim NC or NO - tell us which you need.
This is a genuine AirTAC part, and the surrounding 3V1 family covers both rest states, all five coil voltages, flying-lead as well as DIN entry, and manifold bases. We do not quote pressure, flow or coil power for this family; those datasheet values come back with your RFQ from our engineering desk.

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 3V120-M5-A Is Used
Repair-bench hold-down
A maintenance workshop holds a pump housing square on a repair jig with a compact spring-return cylinder while fasteners are torqued, switched from the workshop's 220V supply.
Trailer rear-door latch
A small spring-return latch cylinder on a delivery trailer's rear door is fed and vented through an M5-port valve wired into the cab control circuit.
Vision lens air purge
A periodic air pulse keeps dust off a machine vision lens on a filling line; the small M5 jet is pulsed from the 220V control panel between inspection cycles.
Is the Airtac 3V100 Solenoid Valve 3V120-M5-A the Right Part?
M5 suits the smallest jobs - a compact spring-return cylinder, an air needle jet, a pilot signal. If the actuator is bigger, the same family steps up through 1/8in, 1/4in and 3/8in ports, on PT thread as standard with G and NPT to order. NC (dead at rest) versus NO (live at rest) is a fail-safe decision, and this code leaves it open, so state your requirement in the RFQ. The 220V AC coil has to match the panel supply; no coil can be rewired for a different voltage. A 3/2 valve drives single-acting actuators only - a double-acting cylinder is out of reach here and calls for the 5-port AirTAC 4V series. Since flow data for this family is not in our published set, ask us to verify sizing against your actuator before ordering; buyers who need printed figures immediately can turn to the AirTAC 3V2 (1/8in, 1/4in) and 3V3 (1/4in) bodies, where flow and coil power are documented.
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 3V120-M5-A FAQ
Those are datasheet figures this page does not carry, so our engineers confirm them when you send an RFQ. If you want numbers already in print, the AirTAC 3V2 and 3V3 3-port bodies have documented flow and coil-power data and are worth comparing first.
M5 is the smallest thread here, matched to compact single-acting cylinders, needle jets and pilot lines; larger loads should step up to the 1/8in, 1/4in or 3/8in versions. Whatever the port, a 3/2 valve cannot drive a double-acting cylinder - that needs a 5-port AirTAC 4V valve.
