AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCAI)
The AirTAC AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCAI) 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 (3V31008NCAI)
A 3/2 valve does one thing well: it feeds a single outlet with air, or vents that outlet to exhaust. The 3V31008NCAI is AirTAC's normally closed version with a 1/4in port, so the downstream actuator sits at exhaust until the coil is energised and cannot creep while the machine is off.
The I at the end of the code is the practical difference on this SKU: the coil arrives with a flying lead, pre-wired for direct connection, instead of terminating in a DIN plug socket. It is still a genuine AirTAC part, and the rest of the family offers the other state, four more coil voltages, DIN entry and 3V-F manifold bases. Any datasheet figure you need - pressure, flow, coil power - we will confirm for you on request.

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 (3V31008NCAI) Is Used
Machine retrofit wiring
Replacing a worn valve on an older press where the electrician lands the flying lead straight into the machine junction box.
Conveyor stopper
Actuating a spring-return pop-up stopper or gate on a packaging conveyor, released whenever control power drops.
Bench test rigs
Switching air to a test fixture in a lab or QC cell where a single-acting ram loads a sample.
Is the AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCAI) the Right Part?
With flying leads, plan the wiring route before the valve is mounted: the lead is fixed at the factory and there is no plug to re-terminate. The state choice is unchanged across the family - normally closed here vents on power loss, normally open holds the outlet fed. A 1/4in port suits a mid-size single-acting cylinder or a decent-length blow line; step down to 1/8in for small actuators.
Because flow data for this family is not in our hands, we suggest sending the actuator details with your RFQ so we can size it from the datasheet. Buyers who need published numbers immediately can look at the documented 3V2 and 3V3 bodies instead. Double-acting cylinders are outside what a 3/2 can drive; that job belongs to the 4V series.
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 (3V31008NCAI) FAQ
No; it is only how the coil is connected. The I suffix means a lead-out wire, while the rest of the family terminates in a DIN socket. For the numbers that do matter - pressure range, flow, coil power - send an RFQ and we will confirm them from the datasheet; the 3V2 and 3V3 bodies publish theirs.
Normally closed vents the outlet when power is lost, so a spring-return clamp or stopper releases itself. Normally open keeps supplying air in that state. Pick by what should happen at your machine on a power cut - never by port size.
