Airtac 3V1 Solenoid Valve 3V1M5BI7F
The AirTAC Airtac 3V1 Solenoid Valve 3V1M5BI7F 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 3V1M5BI7F
The 3V1M5BI7F is a seven-station manifold assembly of AirTAC 3V1 3/2 solenoid valves with M5 ports. Each valve is direct-acting with a single solenoid and spring return: energise it and the outlet is fed, cut power and the spring shifts it back so the line vents. That feed-or-vent action suits single-acting cylinders, air blow, clamps and pilot signalling.
The DC24V coil draws only 3.0 W, so a full seven-valve block still loads the supply modestly, and the IP65 (DIN 40050) construction shrugs off dust and splash. Each valve arrives with a pre-wired flying lead in place of a DIN socket, which shortens panel wiring on compact multi-valve assemblies. It is supplied in a single fixed initial state - confirm it on the datasheet.

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 3V1M5BI7F Is Used
Compact gripper block
Seven valves on one shared manifold drive miniature spring-return grippers and ejector pins across an electronics assembly cell, replacing seven separate mounts with a single M5-port block.
Flying-lead machine retrofit
On an older packaging machine, pre-wired flying leads on each DC24V valve let technicians swap a worn valve plate without re-terminating DIN sockets inside a cramped panel.
Pre-coating PCB blow-off
A pulsed M5 air jet, fed and vented by one valve, clears dust from printed circuit boards just before they enter the conformal-coating booth.
Is the Airtac 3V1 Solenoid Valve 3V1M5BI7F the Right Part?
3V1 is the smallest, lowest-power body in the 3V family, and AirTAC publishes no Cv or effective-area figure for it, so any flow-critical M5 duty should be checked with us first. Where you need more throughput, step up to 3V2 (1/8" and 1/4" ports, NC or NO selectable, Cv 0.18-0.19, rated for vacuum) or 3V3 (1/4" port, Cv 0.62). If manifold density matters more than flow, 3V2M is the purpose-built alternative. A double-acting cylinder needs a 5-port valve - specify the AirTAC 4V series instead.
Five checks before you order this assembly: the M5 port, DC24V coil, flying-lead entry rather than a DIN socket, seven stations on the shared manifold, and confirmation that your fittings suit the M5 connection (M5 carries no separate thread code).
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 3V1M5BI7F FAQ
Operating pressure 0-0.8 MPa (0-114 psi); medium temperature -20 to 70 C; air filtered through a 40 um or finer element, no lubrication needed. Coil power across the 3V1 range: AC220V 4.5 VA, AC110V 4.5 VA, AC24V 5.0 VA, DC24V 3.0 W, DC12V 2.5 W - this SKU draws 3.0 W at DC24V. Protection is IP65 (DIN 40050). No Cv or effective-area figure is published for 3V1; confirm flow from the datasheet or send us an RFQ.
Each valve feeds or vents a single line, so it suits single-acting spring-return cylinders, on/off air blow, clamping and pilot signalling to a larger valve. It cannot drive a double-acting cylinder - that requires a 5-port valve such as the AirTAC 4V series. With seven valves sharing one base, you replace seven individual mounts with a single block, saving panel space.
