AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCFI)
The AirTAC AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCFI) is a genuine 3-port 2-position (3/2) solenoid valve with 1/4 in ports. A 3/2 valve either feeds its outlet or vents it to exhaust, so it suits single-acting cylinders, air blow, clamping, vacuum switching and pilot duty. We stock this code and confirm its published figures from the datasheet on request.

About the AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCFI)
The 3V31008NCFI is AirTAC's normally closed 3/2 solenoid valve with a 1/4in port and a DC12V coil, ordered with flying-lead entry. The I in the code means the coil arrives with lead-out wires: you splice straight into your loom instead of fitting a plug to a DIN socket, which suits machines whose wiring is hard-wired at build. Functionally it is a 3/2 valve - supply, outlet and exhaust, two states, feeding the outlet when energised and venting it when not.
It is a genuine AirTAC part, and the family around it covers both states, five voltages, DIN and lead-out entries, and manifold bases for a shared supply. We do not keep published pressure or flow figures for this body on hand; tell us your actuator in an RFQ and we will come back with the datasheet numbers.

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 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCFI) Is Used
Conveyor reject blow-off
Firing an on/off jet that pushes rejected packs off a sorting conveyor, with the lead-out wires spliced into the panel loom.
Fluids lab bench rig
Piloting a demonstration spring-return cylinder on a university teaching bench where leads are soldered directly to the bench wiring.
Harvester header clamp
Venting a spring-return header clamp on a combine harvester, hard-wired into the machine's 12V loom at the factory.
Is the AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCFI) the Right Part?
The I at the end of this code is the wiring story: the DC12V coil arrives with lead-out wires for splicing straight into a machine loom, with no DIN socket to buy or fit. Beyond that it is the same working configuration as its DIN twin - normally closed, 1/4in port, air to the outlet only while energised and vented when it is not.
Order the DIN version instead if you prefer plug-in service swaps, and remember the coil must be fed 12V DC. Thread across this family is PT as standard; G and NPT are orderable options. Because this family's pressure and flow figures are not published here, send the actuator data and we will confirm the numbers by RFQ; the AirTAC 3V2 (1/8in and 1/4in) and 3V3 (1/4in) bodies have documented flow and coil power if you need them now. Driving a double-acting cylinder? That is the AirTAC 4V series' job.
Confirm before you order
- ✓ Port size and thread (PT from stock; G / NPT to order)
- ✓ Initial state — NC or NO, ordered up front
- ✓ 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 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 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCFI) FAQ
Everything performance-related: operating pressure, flow, coil power, temperature limits and response time, all read from the genuine AirTAC datasheet once you raise an RFQ. When published figures are needed before quoting, the AirTAC 3V2 and 3V3 bodies are the ones with documented data.
Single-acting spring-return cylinders, on/off blow lines, clamps and vacuum ejectors are the natural jobs for a 3/2 valve. A double-acting cylinder needs pressure on both sides, so it needs a 5-port AirTAC 4V valve instead.
