AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCB-W)
The AirTAC AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCB-W) 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-W)
Three ports, two states: a 3/2 valve connects supply to outlet in one state and dumps the outlet to exhaust in the other. In the 3V31008NCB-W that switching happens through a 1/4in port, one step up from 1/8in, which is the size to reach for when a single-acting cylinder or clamp has enough volume that a smaller port would slow the cycle. The coil is DC24V, and normally closed behaviour applies: no air at the outlet until the coil is energised.
This is a genuine AirTAC part. The same family covers M5, 1/8in, 1/4in and 3/8in ports, NC and NO states, all five voltages, both electrical entries and shared-supply 3V-F bases. Pressure, flow and coil-power figures live on the datasheet - ask, and we will send them.

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-W) Is Used
Jig clamp on a welding fixture
A control signal energises the valve to clamp a panel into a welding jig; releasing the signal vents the line so the spring-return clamp opens and the welded part can be lifted out.
Pneumatic stopper on a conveyor
A spring-raised stopper blade on a packaging conveyor is held down by a single-acting cylinder. This valve feeds the cylinder to let cartons pass, and vents it to raise the stopper and halt the flow.
Threaded-part blow-down
After a tapping or assembly operation, energise the valve to blow machined chips and coolant residue out of a threaded housing before the part moves to inspection.
Is the AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCB-W) the Right Part?
The port steps through M5, 1/8in, 1/4in and 3/8in across the family; at 1/4in this valve feeds bigger single-acting cylinders and clamps than the 1/8in bodies, and 3/8in exists if your actuator is larger still. NC gives you a vented, air-free outlet whenever the coil is off - the fail-safe direction for most clamping. DC24V is fixed at order time and must match the panel; DIN plug entry takes a field-fitted connector, and the default thread is PT with G and NPT available as options. If several valves on one machine could share a feed, a 3V-F manifold base consolidates supply and wiring and makes fault-finding simpler. We have no published flow figure for this family in hand, so let us confirm the size against your actuator via RFQ; the documented 3V2 and 3V3 bodies publish flow and coil power now, and the 4V series is the answer for double-acting cylinders.
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-W) FAQ
Ask what must happen when control power fails. Normally closed shuts the outlet and vents it, so a spring-return cylinder relaxes - usually the safe direction for clamps. Normally open keeps air flowing when de-energised, for jobs where loss of signal must not stop the flow. Both states exist across this 3V family.
Not on this page - we hold no published figures for this family and will not estimate. Request the datasheet through the RFQ and we will confirm pressure, flow and coil power. The documented 3V2 (1/8in and 1/4in) and 3V3 (1/4in) bodies publish those figures if you need them right away.
