AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NOB)
The AirTAC AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NOB) 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 (3V31008NOB)
The 3V31008NOB is a 3-port, 2-position (3/2) solenoid valve from the AirTAC 3V3 body group. A 3/2 valve holds one supply port, one outlet and one exhaust, and it sits in one of two states: feed the outlet, or vent it. Because this version is normally open, air passes to the outlet for as long as the coil is de-energised; switching the DC24V coil on shuts the supply and dumps the outlet to exhaust. That is the behaviour you want wherever air must be present until the control system says otherwise, or where losing power should leave the line blowing or vented rather than sealed.
This is a genuine AirTAC part, and the rest of the code is fixed too: a 1/4in (08) PT port, a DC24V coil and a DIN plug electrical entry. Within the same family you can order normally closed versions, any of five coil voltages (AC220V, DC24V, AC110V, AC24V, DC12V), flying-lead entry instead of the DIN plug, and 3V-F manifold bases for multi-valve panels. Pressure, flow and coil-power figures for this group are not in our kit - tell us the application and we will confirm them from the AirTAC datasheet on request.

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 (3V31008NOB) Is Used
Bottle rinsing blow-off
A nozzle bank on a bottling line that strips rinse water from PET bottles before the labeller: air reaches the outlet the whole shift, and the coil only interrupts it when the controller calls a stop.
Fail-vent clamp circuit
A spring-return clamp on a press brake whose jaw must release rather than stay locked when the machine is switched off - with a normally open valve, cutting power leaves the outlet dumped to exhaust.
Clutch drop-out at shutdown
An air-engaged clutch on a packaging machine that must not stay engaged overnight: the normally open state vents the clutch line the moment the 24V control supply is removed.
Is the AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NOB) the Right Part?
Normally open is the fail-air choice: de-energised, the valve feeds the outlet; energised, it shuts the supply and exhausts the outlet. Choose it when the machine must keep blowing, feeding or venting while powered down, and choose normally closed when the reverse is true. The 1/4in PT port sits above the 1/8in size in this family, so it suits a bigger single-acting actuator; the DC24V coil must match a 24 volt DC panel supply, and the DIN plug entry takes a socket connector instead of flying leads. We do not hold published flow figures for this family in our kit, so ask us to confirm sizing against your actuator before ordering - and if you want a 3-port valve with flow and coil power published today, the documented AirTAC 3V2 and 3V3 bodies are where those figures live. Driving a double-acting cylinder is outside any 3/2 valve; that job belongs to 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 (3V31008NOB) FAQ
Not on this page. We hold no datasheet extract for the 3V3x0 family in this kit, so we publish no performance numbers rather than guess them - send the RFQ and we will read the pressure range, flow and coil power off the genuine AirTAC datasheet for you. If you need figures on screen straight away, the documented AirTAC 3V2 and 3V3 port-coded models have them published.
No. Three ports and two positions are enough to feed and vent a single-acting (spring-return) cylinder, switch a blow line or pilot a bigger valve, but a double-acting cylinder needs pressure on both sides in turn. That takes a 5-port valve - use the AirTAC 4V series for that job.
