AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCB)
The AirTAC AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCB) 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 (3V31008NCB)
The 3V31008NCB runs its coil on DC24V, the voltage most common on machine control panels with a dedicated 24V supply. As a 3/2 valve it has a supply port, an outlet and an exhaust, and two positions; being normally closed, the 1/4in outlet stays vented until the coil is energised. On power loss the downstream single-acting actuator exhausts rather than holds.
It is a genuine AirTAC part, and the coil voltage is fixed at the factory - DC24V here, with AC220V, AC110V, AC24V and DC12V available elsewhere in the family alongside the NO state, flying-lead entry and manifold bases. We do not publish flow or power figures on this page; send the RFQ with your actuator details and we will confirm the datasheet values.

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 (3V31008NCB) Is Used
Guard door interlocks
Releasing a spring-return interlock or lock-out cylinder on a machine guard, venting automatically when control power fails.
Pick-and-place grippers
Opening or closing a spring-return gripper on a small robot or pick-and-place unit, one valve per motion.
Tray filling heads
Switching fill or eject air to individual heads on a multi-lane tray filling machine.
Is the AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCB) the Right Part?
Check the control voltage before anything else: this coil is DC24V and cannot be rewired for another supply, so pick the matching suffix if your panel runs AC220V or one of the other three options. Then choose the state - normally closed here, venting the outlet whenever the coil drops out. The 1/4in port is the step above 1/8in for larger single-acting cylinders.
Because this family's flow figures are not available to us, ask us to confirm sizing from the datasheet with your RFQ. If your project needs a 3-port valve whose flow and coil power are already documented, the AirTAC 3V2 (1/8in and 1/4in) and 3V3 (1/4in) bodies are the ones to look at. For double-acting cylinders, move to the 5-port 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 (3V31008NCB) FAQ
Raise an RFQ and we will confirm operating pressure, flow and coil power from the AirTAC datasheet before you order. If your schedule needs published figures in hand right now, the 3V2 and 3V3 valve bodies in this family carry documented flow and coil-power data.
The coil is built for DC24V and must be fed from a matching 24V source; a coil cannot be converted to another voltage by wiring. Keep solenoid loads and sensitive sensor circuits on separate fused ways, and filter the air supply before the valve.
