AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCBI)
The AirTAC AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCBI) 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 (3V31008NCBI)
The 3V31008NCBI is a 3-port, 2-position solenoid valve from the AirTAC 3V310 body. Three ports mean supply, outlet and exhaust; two positions mean the valve either feeds the outlet or vents it. Normally closed, this one holds the outlet vented until the DC24V coil is energised, so anything downstream stays depressurised while the panel output is off. The 1/4in port steps up from the 1/8in sizes and suits a larger single-acting cylinder or a heavier blow-off duty.
It is a genuine AirTAC part. The same 3V310 body is catalogued in both NC and NO states, five coil voltages (AC220V, DC24V, AC110V, AC24V, DC12V) and both DIN-plug and flying-lead electrical entries, with 3V-F manifold bases available for multi-valve layouts. Pressure, flow and coil power are not published on this page; send an RFQ and we will read the figures off the datasheet for you.

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 (3V31008NCBI) Is Used
CNC fixture clamping
Energise to clamp a machined part in a jig; lose power and the spring-return clamp retracts, releasing the workpiece safely.
Packaging line blow-off
A short pulse of compressed air clears crumbs and dust from trays or film before sealing, and the vented NC state keeps the nozzle dead between pulses.
PLC panel wiring
The flying lead lands straight on PLC output terminals, which suits compact cabinets where a plug-on socket adds bulk.
Is the AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCBI) the Right Part?
Choose NC when the safe condition is no air at the outlet: on power loss the outlet vents and a spring-return cylinder retracts. NO is the mirror image and exists in this family if your fail-safe runs the other way. The 1/4in port pairs with a bigger single-acting actuator than a 1/8in valve would; the DC24V coil must match a 24-volt DC panel supply, which rewiring cannot change. Flying-lead entry arrives as pre-terminated wires for terminal connection, where the DIN-plug variants take a plug-on connector. If you are grouping several 3/2 valves, a 3V-F manifold base shares one air supply across them. We hold no published flow figure for this family, so ask us to check sizing against your cylinder before ordering; the 3V2 and 3V3 bodies have documented flow and coil-power figures if you need published numbers today. A double-acting cylinder needs a 5-port valve, not this one - the AirTAC 4V series is the route.
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 (3V31008NCBI) FAQ
Pressure range, flow, coil power and the rest of the datasheet are not on this page, but we will confirm every number from the manufacturer datasheet on request. If you need published figures before you enquire, the AirTAC 3V2 (1/8in and 1/4in) and 3V3 (1/4in) bodies are the fully documented alternatives in this 3/2 family.
No. A 3/2 valve has one outlet and either feeds it or vents it, which suits single-acting, spring-return cylinders, blow-off and piloting. A double-acting cylinder needs pressurised air at both ends, so specify a 5-port valve from the AirTAC 4V series instead.
