AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NOBI)
The AirTAC AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NOBI) 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 (3V31008NOBI)
The 3V31008NOBI is a 3/2 solenoid valve: three ports (supply, outlet, exhaust) and two positions, feeding the outlet in one state and venting it in the other. This version is normally open, so the outlet is fed while the coil is off and the DC24V coil closes it when energised. Its 1/4in port is the step up from 1/8in in this family and suits a larger spring-return actuator.
It is a genuine AirTAC part, and the I in the code marks flying-lead entry: the coil arrives with pre-wired leads rather than a DIN plug socket, which suits sealed enclosures and tight cabinets where a connector will not fit. Elsewhere in the family you will find normally closed variants, five coil voltages, DIN entry and 3V-F manifold bases. Pressure, flow and coil-power figures are not published on our side - ask by RFQ and we will confirm 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 (3V31008NOBI) Is Used
Sorting-line stoppers
Raises and lowers the pneumatic stopper that holds parcels between conveyor belts on a distribution line. The 1/4in port matches the stopper cylinder's fittings.
Bench pneumatic press
Feeds a spring-return air cylinder on a small bench press used for staking or marking. With this normally open version, the ram stays fed when power is off.
Robot gripper lock
Actuates the spring-return lock on a robot end-of-arm gripper, feeding it to secure the part and venting it to exhaust when the job changes.
Is the AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NOBI) the Right Part?
Because this valve is normally open, de-energised means air-on at the outlet - pick NO only if that is the fail-safe direction you want, otherwise order the NC variant. The flying-lead entry saves fitting a DIN connector, but the leads still need terminating to a DC24V supply that matches the coil exactly; a coil is wound for one voltage and cannot be converted by rewiring. The 1/4in port takes larger fittings than M5 or 1/8in, which matters when the downstream single-acting cylinder has a bigger bore, and PT thread is the standard supply for this port, with G and NPT orderable. If several valves will sit side by side, a 3V-F base carries them on one air feed and one wiring loom, which makes fault-finding quicker. Flow and pressure data for this family sit on the AirTAC datasheet rather than on our pages - send the RFQ with your actuator details and we will confirm sizing. Where published figures are needed immediately, the AirTAC 3V2 and 3V3 3-port bodies document flow and coil power. Double-acting cylinders need a 5-port valve; see the AirTAC 4V range.
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 (3V31008NOBI) FAQ
Pressure range, flow and coil power for this family come from the AirTAC datasheet rather than our pages. Send the RFQ with your actuator details and we will confirm them. If you need figures published on the page itself, the AirTAC 3V2 (1/8in and 1/4in) and 3V3 (1/4in) bodies are the documented alternative.
Flying-lead entry: the coil is supplied with pre-wired leads instead of a DIN plug socket. Terminate the leads to a matching DC24V supply - the coil voltage cannot be changed by rewiring. If you prefer a plug-in connector, order the variant without the I.
