Airtac 3V1 Solenoid Valve 3V1M5BI3F
The AirTAC Airtac 3V1 Solenoid Valve 3V1M5BI3F 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 3V1M5BI3F
Three 3/2 direct-acting solenoid valves, one manifold: the 3V1M5BI3F puts three independently switched M5-ported stations on a single base. Each station feeds or vents its own line, so one assembly can run a clamp, a blow-off jet and a pilot signal from one tidy footprint.
The DC24V coils draw 3.0 W each and are sealed to IP65 per DIN 40050, so splash and dust on the machine frame are not a wiring worry. Flying leads exit each coil, ready to land on your PLC output card or terminal rail.

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 3V1M5BI3F Is Used
Reject gate on a bottling line
One station snaps the single-acting gate to eject a faulty bottle, another blows it clear of the chute and the third pilots the counting sensor - all from one base.
Pneumatic stopper and push-off on a carton conveyor
A spring-return stopper blade halts cartons at the pick station while a second valve drives the pusher, venting safely whenever the PLC output drops.
Valve bank inside a compact control cabinet
Three flying-lead stations terminate straight onto PLC output terminals, giving a machine builder three 3/2 functions without DIN connectors cluttering the door.
Is the Airtac 3V1 Solenoid Valve 3V1M5BI3F the Right Part?
Three stations of 3/2 control on one M5 base makes this a compact alternative to three loose valves - but check the flow budget. 3V1 has no published Cv or effective area, so for flow-critical duties compare against the 3V2 (1/8 and 1/4 ports, NC or NO selectable, Cv 0.18-0.19, rated for vacuum) or the 3V3 (1/4 port, Cv 0.62); when dense packaging matters more than flow, 3V2M is the manifold-first choice. Remember a 3/2 valve feeds or vents one line - it cannot drive a double-acting cylinder, which needs an AirTAC 4V valve.
The code settles four of the five checks: M5 port, DC24V coil, flying-lead entry, 3-station manifold. Confirm only the port family (M5 vs 1/8), the thread on 1/8 versions (PT is the family standard; G and NPT are orderable options) and the station count you actually need, from 1F up to 20F.
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 3V1M5BI3F FAQ
Each station works from 0-0.8 MPa (0-114 psi) between -20 and 70 C. Coils are DC24V at 3.0 W, protected to IP65 (DIN 40050), and the air supply must be filtered to 40 um or finer. No Cv is published for 3V1, so confirm flow-critical duties with us.
Yes - the 3V1 family is offered as series-mounted assemblies from 1F to 20F stations, so the same M5, DC24V, flying-lead format can be reordered with more or fewer stations as the machine design changes. Individual valves and DIN-plug entry versions also exist.
