Airtac 3V1 Solenoid Valve 3V1M5B5F
The AirTAC Airtac 3V1 Solenoid Valve 3V1M5B5F 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 3V1M5B5F
The 3V1M5B5F is a five-station manifold assembly of AirTAC 3V1 valves: five direct-acting 3/2 units sharing one M5 air supply, each with its own DC24V coil drawing just 3.0 W. Every station is a single-solenoid, spring-return valve that either feeds its outlet or vents it to exhaust.
That makes the block a compact way to switch single-acting cylinders, air blow or pilot signals from one panel position. Coil housings meet IP65 (DIN 40050) and each valve carries a manual override for setup. The valve is supplied in a single fixed initial state - confirm it on the datasheet before wiring.

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 3V1M5B5F Is Used
CNC jig clamp control
Each station pressurises a small spring-return clamp that holds an aluminium bracket during a drilling cycle, then vents it so the spring releases the part the moment power drops.
Blow-off nozzle sequencing
One manifold position pulses an air-blast nozzle that clears swarf from a tapped M6 hole between machining cycles, triggered straight from the PLC output.
Pilot stage for a process valve
A single station's outlet sends the pilot signal that shifts a larger diaphragm valve on a compact water-treatment skid, with the M5 manifold keeping tubing runs short.
Is the Airtac 3V1 Solenoid Valve 3V1M5B5F the Right Part?
3V1 is the smallest, lowest-power body in the AirTAC 3V range and has no published Cv, so for flow-critical jobs ask us to check the duty before you commit. Need more flow? Step up to 3V2 (1/8in and 1/4in, NC or NO selectable, Cv 0.18-0.19, and rated for vacuum) or to 3V3 (1/4in, Cv 0.62). If a dense manifold matters more than flow, 3V2M is the series to compare. Double-acting cylinders need a 5-port valve - see the AirTAC 4V series.
Before ordering, match five points: the M5 port against your fittings (this size carries no separate thread code), the DC24V coil, the DIN plug entry, the number of stations on the shared base, and the mounting hardware. Accessories 3V1-P30, 3V1-P31 and 3V1-P32 cover base screws, seals and 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 3V1M5B5F FAQ
Working pressure is 0-0.8 MPa (0-114 psi), the fluid and ambient window is -20 to 70 C, and coil housings are IP65 (DIN 40050). Coil power by voltage: AC220V 4.5 VA, AC110V 4.5 VA, AC24V 5.0 VA, DC24V 3.0 W, DC12V 2.5 W. This SKU uses the 3.0 W DC24V coil. No Cv or effective-area figure is published for 3V1.
Each station is a 3/2 valve: it feeds one line or vents it to exhaust. That suits single-acting spring-return cylinders, air-blast nozzles, clamping and pilot signals for larger valves. It will not run a double-acting cylinder - that needs a 5-port valve such as the AirTAC 4V series. Air must be filtered to 40 um or finer; lubrication is not required.
