AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCBI-W)
The AirTAC AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCBI-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 (3V31008NCBI-W)
A 3/2 valve gives you two outcomes on one outlet: air flows from supply, or the outlet dumps to exhaust. The 3V31008NCBI-W is the normally closed member of the AirTAC 3V310 body in 1/4in port size, so the outlet stays open to exhaust and no air reaches the actuator until the DC24V coil pulls in. That single behaviour is what makes a spring-return cylinder retract, a blow-off nozzle go quiet and a vented clamp stay safe the moment power drops.
This is a genuine AirTAC part. Across the family you can also order the normally open state, coils in AC220V, DC24V, AC110V, AC24V or DC12V, DIN-plug or flying-lead entry, and 3V-F manifold bases from one to twenty stations. Datasheet numbers for pressure, flow and coil power sit outside this page - raise an RFQ and we will confirm them line by line.

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 (3V31008NCBI-W) Is Used
Single-acting air press
Feeds a spring-return cylinder on a small punching or marking press; de-energising vents the cylinder so the ram lifts on its spring.
Lab suction-cup switching
Switches a compact vacuum generator on a pick-and-place cell, feeding the generator from supply and releasing it to exhaust.
Piloting a larger valve
Sends a pilot signal to a big process or directional valve, letting a 24V DC control output operate a far larger main line.
Is the AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NCBI-W) the Right Part?
Start from the actuator: the 1/4in port is the larger step in the family and is the choice when a 1/8in valve would restrict a big single-acting cylinder - but the correct check is a flow comparison, and this family's flow figures are not published here, so ask us to run the datasheet against your cylinder size before you commit. The NC state vents the outlet on power loss; NO does the opposite and is orderable in the same body. The DC24V coil suits a 24V DC control panel and cannot be altered by rewiring; flying-lead entry wires straight to terminals, DIN-plug variants take a detachable connector. For grouped valves, the 3V-F manifold bases carry several valves on one shared supply and one wiring loom, which shortens fault-finding. If you need a 3/2 valve with published flow and coil power today, the documented AirTAC 3V2 and 3V3 bodies are the answer; if your cylinder is double-acting, move to the 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 (3V31008NCBI-W) FAQ
They are not published on this page because we do not hold this family's specification sheet. Tell us your actuator and supply by RFQ and we will confirm the datasheet figures for you. If you want published numbers right now, the AirTAC 3V2 and 3V3 bodies carry documented flow and coil-power figures.
Decide what must happen when power or air is lost. NC (this valve) leaves the outlet vented, so a spring-return cylinder retracts and a nozzle stays off. NO leaves the outlet fed, suiting circuits that must keep running through a power cut. Both states exist in the 3V310 body at every voltage.
