AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NOA)
The AirTAC AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NOA) 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 (3V31008NOA)
A 3/2 solenoid valve has three ports - supply, outlet, exhaust - and two states: feed the outlet, or vent it. This 3V31008NOA is normally open, so with the coil off, supply flows through to the outlet; energising the coil blocks the supply and vents the downstream line. The coil is wound for AC220V, so it drops straight into a standard single-phase control panel without a separate power supply, and it connects through a DIN plug.
It is a genuine AirTAC part in the 3V310 series. The same body is catalogued in NC as well as NO, in four further coil voltages (DC24V, AC110V, AC24V, DC12V), with a flying-lead entry as the wiring alternative, and the 3V-F bases let you mount several valves on one shared air supply. Flow and pressure data for this family do not appear on our pages - send us your actuator details and we will confirm the figures from 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 3V310-08 Solenoid Valve, 3V300 Series (3V31008NOA) Is Used
Piloting a process valve
On a bottling line, the 3/2 switches an air signal to a larger diaphragm process valve, giving the PLC a compact way to open and close the main product line.
Fixture clamping station
Each station on a welding fixture uses one 3/2 valve to switch air to a single-acting clamp and to vent it on release, with the exhaust dumping locally at the valve.
Label blow-off between gaps
On a conveyor carrying adhesive labels, a normally open air jet runs continuously and the control system energises the valve only in the moments when the label must pass dry.
Is the AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NOA) the Right Part?
Start with the panel, not the valve: the coil on this unit is AC220V and cannot be changed by rewiring, so if your control supply is DC24V or one of the other family voltages, order that voltage letter instead. The state is NO - air passes to the outlet while the coil is off - which suits circuits that must keep flowing on a power failure; choose NC where the outlet must stay dead until energised. The 1/4in port takes the larger hose sizes in this family, and PT is the standard thread with G and NPT offered as options.
On sizing, be straightforward with us: this family's flow figures are not something we can print here, so ask us to size the valve against your single-acting cylinder or blow line from the datasheet before you commit. Where a fully documented 3-port valve is needed today, the 3V2 and 3V3 bodies carry published flow and coil-power figures; for a double-acting cylinder, the 5-port AirTAC 4V series is the correct tool. For several valves sharing one feed and one wiring loom, pair them on a 3V-F manifold base.
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 (3V31008NOA) FAQ
We deliberately keep this page to the decodable configuration - 3/2, NO, 1/4in port, AC220V, DIN plug - and leave performance to the datasheet, which we confirm on request through the RFQ form. If published figures are a hard requirement, the 3V2 and 3V3 series are the documented 3-port bodies with flow and coil power on their own pages.
No - the coil is built for one voltage only, AC220V here, and rewiring will not change it; order the voltage letter you need instead: B for DC24V, C for AC110V, E for AC24V, F for DC12V. The entry on this version is a DIN plug; a flying-lead version can be ordered where direct wiring to a terminal suits the cabinet better.
