Airtac 3V1 Solenoid Valve 3V1M5B7F
The AirTAC Airtac 3V1 Solenoid Valve 3V1M5B7F 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 3V1M5B7F
Seven direct-acting 3/2 stations make up the 3V1M5B7F, each a spring-return AirTAC 3V1 valve with a 3.0 W DC24V coil and DIN plug connection on a shared M5 manifold base. A manual override on every station lets you jog each output by hand during commissioning.
With IP65 (DIN 40050) coil housings and a 0-0.8 MPa working range, the block targets small-panel circuits driving single-acting cylinders, blow nozzles or pilot signals. Air should be filtered to 40 um or finer; lubrication is not required.

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 3V1M5B7F Is Used
Diverting fingers on a sorter
Compact pop-up fingers on a parcel sorter are raised by single-acting rams, one station per lane, nudging cartons between conveyor lines as barcodes are read.
Tab-folding on a carton sealer
At the sealing head, spring-return rams fold the minor box flaps before tape-down, each fold position controlled by its own DC24V manifold station.
Pneumatic marking pin
A dot-peen stylus stamps batch codes onto stainless tags; the 3/2 station pressurises the pin for the strike and vents it so the return spring lifts the tool clear.
Is the Airtac 3V1 Solenoid Valve 3V1M5B7F the Right Part?
Size in both directions. Up: if M5 restrictions limit your flow, 3V2 offers 1/8in and 1/4in ports with Cv 0.18-0.19, NC or NO selection and a vacuum rating, while 3V3 gives 1/4in at Cv 0.62; 3V2M is the alternative when manifold density outranks flow. 3V1 itself carries no published Cv, so send flow-critical duties to us for confirmation. For double-acting cylinders you need the 5-port AirTAC 4V series.
Five points to lock down before you order: the M5 port (no separate thread code exists at this size), the DC24V coil voltage, the DIN plug entry, seven stations on one shared base, and mounting hardware - 3V1-P30 base screws, 3V1-P31 O-rings and long screws, 3V1-P32 brackets.
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 3V1M5B7F FAQ
Yes: 0-0.8 MPa (0-114 psi) operating pressure, -20 to 70 C temperature range, IP65 (DIN 40050) protection. Coil power depends on voltage - AC220V 4.5 VA, AC110V 4.5 VA, AC24V 5.0 VA, DC24V 3.0 W, DC12V 2.5 W - and this model uses the 3.0 W DC24V version. Cv is not published for 3V1.
Each of the seven stations carries a manual override, so you can shift a valve by hand and check its downstream actuator during installation and commissioning without energising the 3.0 W DC24V coil. The valve is supplied in a single fixed initial state - confirm it on the datasheet before tying the circuit into your logic.
