AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NO-X0)
The AirTAC AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NO-X0) 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 (3V31008NO-X0)
The 3V31008NO is a 3-port, 2-position solenoid valve: one supply port, one outlet and one exhaust, with exactly two states - feed the outlet, or vent it. This version is normally open, so the outlet receives air whenever the coil is de-energised; energising the coil closes the supply path and vents the downstream side to exhaust. That default-flow behaviour is what you want where air must keep moving through a power cut and a signal should stop it.
It is a genuine AirTAC part from the 3V310 body. Across the wider 3V1, 3V2 and 3V3 family you can order either state (NC or NO), any of five coil voltages (AC220V, DC24V, AC110V, AC24V, DC12V), a DIN plug or a flying-lead entry, and 3V-F manifold bases that carry several valves on one shared supply. The coil voltage on this particular listing is confirmed when you order. Pressure, flow and coil-power figures are not published on this page - raise an RFQ and we will return them 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 (3V31008NO-X0) Is Used
Hold-through-power-loss clamping
On a transfer-line fixture, a spring-return clamp must stay engaged through a control-power drop; a normally open valve keeps it fed, and the PLC energises the coil to vent and release once the part is clear.
Default-on chip blow
A machining cell wants air on the tool tip whenever the spindle stops; with a normally open valve the blow runs by default and the controller energises the coil to shut it off during cutting.
Single-acting press cylinder
A small bench press with a spring-return cylinder needs one air path in and one exhaust path out; a 3/2 valve provides exactly that pair of states.
Is the AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NO-X0) the Right Part?
Choose NO over NC when the safe condition is flow: if the coil loses power, this valve keeps the outlet fed. If your requirement is the opposite - no air at the outlet until the coil is energised - order the NC version of the same body instead. The 1/4in port fits the larger single-acting cylinders and blow lines in the family's range, and PT is the standard thread, with G and NPT available as catalogue options.
Two points to settle before you order. First, coil voltage: the family is offered in AC220V, DC24V, AC110V, AC24V and DC12V, and the voltage supplied under this listing should be confirmed with us. Second, sizing: published flow figures for this family are not in our hands, so ask us to check the datasheet against your actuator before ordering. If you want a 3-port valve with published flow and coil power on the page today, look at the documented 3V2 and 3V3 bodies - and if your cylinder is double-acting, you need the 5-port AirTAC 4V series, not this valve. Running several valves off one air feed? Order 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 (3V31008NO-X0) FAQ
Not on this page. Configuration is what we document here; the pressure range, flow and coil power come from the AirTAC datasheet, which we will send or summarise when you raise an RFQ. If you need figures printed on the product page itself, the 3V2 and 3V3 series are the documented bodies with published flow and coil-power figures.
No. A 3/2 valve has only one outlet, so it can switch a single-acting, spring-return cylinder or an air blow line, but a double-acting cylinder needs pressure on both sides in turn - that is a 5-port valve, the AirTAC 4V series. Remember too that this unit is normally open: the outlet stays fed until the coil is energised.
