Airtac 3V1 Solenoid Valve 3V1M5BI-X1
The AirTAC Airtac 3V1 Solenoid Valve 3V1M5BI-X1 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 3V1M5BI-X1
AirTAC's 3V1M5BI-X1 keeps the compact M5 port and DC24V flying-lead coil of the standard 3V1M5BI, while the -X1 suffix marks a catalogue option - confirm its exact scope with us when you request a quote. As a 3/2 direct-acting, spring-return valve it either pressurises or vents one line, so it drives single-acting cylinders, air blow, clamps or pilots a larger valve, with a 3.0 W coil.
The temperature span is -20 to 70 C and the IP65 (DIN 40050) coil suits sealed electrical enclosures or shielded machine frames. Feed it air filtered to 40 um or finer; lubrication is not required, which keeps the supply side simple.

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 3V1M5BI-X1 Is Used
Field swap inside a printing head
A service technician replaces a failed solenoid in the cramped plumbing of a coding-print head; the M5 port and pre-wired lead make the exchange a screwdriver job.
Pilot stage on a process skid
Mounted beside a larger diaphragm process valve, the 3.0 W coil provides the pilot signal that shifts the main valve without loading the skid's control supply.
Gripper bench prototype
On a university robotics bench, the valve actuates a single-acting gripper cylinder, with the spring return opening the fingers the moment the coil drops out.
Is the Airtac 3V1 Solenoid Valve 3V1M5BI-X1 the Right Part?
Size this body in both directions before you buy. 3V1 is the most compact, lowest-power 3V valve and publishes no Cv or effective area, so a flow-critical application should be checked with us first. Need more flow, or an initial state you can select as NC or NO? Move up to 3V2 (1/8in and 1/4in, Cv 0.18-0.19, rated for vacuum) or 3V3 (1/4in, Cv 0.62); if manifold density outranks flow, 3V2M is built for it.
Confirm five things: port (M5 or 1/8in), thread (PT standard on 1/8in; G and NPT are catalogue options to order; no thread code exists on M5), coil voltage, entry (DIN plug or flying lead) and individual valve versus manifold stations. Double-acting actuators belong on the 5-port AirTAC 4V series, not here.
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 Wiring by qualified personnel, per AirTAC documentation.
Airtac 3V1 Solenoid Valve 3V1M5BI-X1 FAQ
Pressure 0-0.8 MPa (0-114 psi), media temperature -20 to 70 C, IP65 protection (DIN 40050). Coil power depends on the winding: 4.5 VA at AC220V or AC110V, 5.0 VA at AC24V, 3.0 W at DC24V (this valve) and 2.5 W at DC12V. Note that AirTAC states no Cv or effective-area value for the 3V1 body, so request flow data for critical sizing.
Three ports and two states mean it either feeds the outlet or vents it to exhaust, so it suits single-acting spring-return cylinders, air blow, clamping and pilot duty. It does not drive double-acting cylinders, which need two outlet ports - specify the 5-port AirTAC 4V series for those. Its air must be filtered to 40 um or finer; lubrication is not required.
