AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCA-W)
The AirTAC AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCA-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 (3V31008NCA-W)
The 3V31008NCA-W is a 3-port, 2-position solenoid valve from AirTAC. Three ports mean supply, outlet and exhaust; two positions mean the outlet is either fed or vented. This unit is normally closed, so with the coil de-energised the outlet sits at exhaust and no air reaches the actuator. The 1/4in port is the larger of the two common connections in this body size, which is the usual pick when a single-acting cylinder has a bigger bore.
It is a genuine AirTAC part, and the family around it is wide: NC and NO states, five coil voltages, DIN plug or flying-lead entry, and 3V-F manifold bases for multi-valve panels. This page carries no pressure, flow or coil-power figures; ask us by RFQ and we will read the datasheet numbers back to you before you commit.

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 (3V31008NCA-W) Is Used
CNC clamping fixture
Switching a single-acting clamp cylinder on a milling fixture, so the workpiece is gripped only while the coil is held energised.
Chip blow-off station
Feeding a blow nozzle that clears chips and swarf from a machining table between cutting cycles.
Pilot stage
Sending a pilot signal to a larger air-operated valve on a process or washdown line.
Is the AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCA-W) the Right Part?
Decide the state first. Normally closed vents the outlet whenever power is lost, which suits a clamp that must release on failure; normally open does the opposite and keeps feeding air. The port step matters too: M5 and 1/8in suit small actuators, this 1/4in connection suits a larger single-acting cylinder, and 3/8in sits above it. Match the coil to the panel supply - AC220V here - because a coil cannot be rewired to another voltage.
We do not hold published flow figures for this family, so ask us to check the datasheet against your actuator before ordering. If you need a 3-port valve with flow and coil power already documented, the AirTAC 3V2 (1/8in and 1/4in) and 3V3 (1/4in) bodies carry published figures today. For a double-acting cylinder you need a 5-port valve - see the AirTAC 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 (3V31008NCA-W) FAQ
They are not published on this page. Send an RFQ and we will confirm operating pressure, flow and coil power from the AirTAC datasheet. If you need figures printed in front of you today, the 3V2 and 3V3 bodies in this family have published flow and coil-power data.
No. A 3/2 valve has one outlet and can only feed or vent a single chamber, so it drives single-acting, spring-return cylinders. A double-acting cylinder needs a 5-port valve such as the AirTAC 4V series.
