Airtac 3V1 Solenoid Valve 3V1M5B3F
The AirTAC Airtac 3V1 Solenoid Valve 3V1M5B3F 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 3V1M5B3F
The 3F code on 3V1M5B3F means three 3V1 valves mounted in series on a shared base, each valve on M5 ports. Every valve is a 3/2-way, direct-acting type with spring return: energise a coil and the outlet is fed; remove power and the spring carries the spool back to the valve's single fixed initial state.
At DC24V each coil takes just 3.0 W, so three valves together place only a light load on a PLC output card or small relay. Protection is IP65 (DIN 40050), a manual override is fitted per station, and 40 um-or-finer filtered air needs no lubrication.

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 3V1M5B3F Is Used
Part ejection on a rotary indexing table
A small-parts press feeder uses three ejector pins around an indexing table; one 3/2 station per pin fires the eject stroke, with the whole block mounted right at the die to keep tubing short.
Bottle-gate sequencing on a filler
Three single-acting gates meter empty bottles into a rinsing carousel; the 3-station manifold keeps the valve block small enough to fit beside the machine's guard door.
Test-rig port switching
An auto-parts leak-test bench connects shop air to three different test ports in turn; the technician triggers each 3.0 W DC24V coil from the bench PLC without rewiring the rig.
Is the Airtac 3V1 Solenoid Valve 3V1M5B3F the Right Part?
Five checks decide the right code: M5 or 1/8in port; PT, G or NPT thread (PT is standard on 3V1, while G and NPT are ordered as options); the coil voltage; DIN plug versus flying-lead entry (this SKU is DIN plug); and one valve or a manifold, where 1F to 20F set the station count.
Because AirTAC publishes no Cv or effective area for the 3V1, confirm flow-sensitive duties with us before ordering. Need more flow? Move up to 3V2 (1/8in and 1/4in, NC or NO selectable, Cv 0.18-0.19, vacuum rated) or 3V3 (1/4in, Cv 0.62). For tightly packed manifolds, 3V2M is the specialist body; for double-acting cylinders, use the AirTAC 4V series.
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 3V1M5B3F FAQ
Expect 0-0.8 MPa (0-114 psi) operating pressure, -20 to 70 C temperature limits, IP65 (DIN 40050) protection and 40 um-or-finer filtered air. Coil power across the family: AC220V 4.5 VA, AC110V 4.5 VA, AC24V 5.0 VA, DC24V 3.0 W, DC12V 2.5 W - all three stations here are 3.0 W DC24V. There is no published Cv for the 3V1 body.
This SKU is supplied with DIN plug sockets, one per station: each coil is wired through a detachable connector, which keeps valve replacement quick on a machine that is serviced often. AirTAC also lists flying-lead (I-coded) 3V1 valves with a pre-wired lead-out for tight cabinets; order that entry style explicitly if you prefer it.
