Airtac 3V1 Solenoid Valve 3V1M5B20F
The AirTAC Airtac 3V1 Solenoid Valve 3V1M5B20F is a genuine 3-port 2-position (3/2) solenoid valve with M5 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 3V1M5B20F
Twenty stations is the densest block the 3V1 family builds, and the 3V1M5B20F is exactly that: twenty 3/2 valves on a single M5 manifold. Each is direct-acting, single-solenoid and spring-return - it either pressurizes its outlet or vents it to exhaust, suiting spring-return actuators, jets and pilot duties. One supply port, twenty controllable outlets, a fraction of the fittings.
Power stays predictable: 3.0 W per DC24V coil, about 60 W if every station energizes together. IP65 (DIN 40050) protection and a manual override at each position round out the package.

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 3V1M5B20F Is Used
Yarn threading jets on a spinning frame
Twenty air-jet nozzles tie on new ends across the spindle bank of a ring-spinning machine, one valve per jet.
Card ejectors on a personalization line
Each station of a card-issuing machine uses a short air puff to push finished cards into the output tray.
Test jets on an EV connector rig
A twenty-way test fixture routes low-pressure air to individual contact cavities to verify seal integrity during end-of-line testing.
Is the Airtac 3V1 Solenoid Valve 3V1M5B20F the Right Part?
At this density, plumbing savings are the headline - but 3V1 remains a small-port, low-flow body with no published Cv, so size up when flow matters: 3V2 (1/8 or 1/4 port, NC/NO selectable, Cv 0.18-0.19, vacuum rated) or 3V3 (1/4 port, Cv 0.62). If you need manifold density with more flow, compare the 3V2M. Double-acting cylinders belong to the 5-port AirTAC 4V family.
Five checks before ordering: M5 port, DC24V coil, DIN plug entry, the 20-station count of this assembly, and your pressure range - the 3V1 covers 0-0.8 MPa. Include duty flow rates in your RFQ and we will verify the fit.
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 3V1M5B20F FAQ
Operating pressure 0-0.8 MPa (0-114 psi), ambient and media temperature -20 to 70 C, IP65 to DIN 40050. Coil power by voltage: AC220V 4.5 VA, AC110V 4.5 VA, AC24V 5.0 VA, DC24V 3.0 W (fitted here), DC12V 2.5 W. Medium is air filtered to 40 um or finer, no lubrication needed. Cv is not published for the 3V1 - never assume one.
Each valve keeps its own DIN plug connection, so your PLC outputs stay one-to-one with stations and a fault can be isolated valve by valve. Every position has a manual override for setup without power. Pneumatically, one supply feeds the whole base - that is what makes twenty M5 outlets practical on a compact machine.
