The AirTAC Airtac 3V Solenoid Valves 3V31010NOFI is a genuine 3-port 2-position (3/2) solenoid valve with 3/8 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.
The 3V31010NOFI is a three-port, two-position solenoid valve in the AirTAC 3V310 body. Its normally open state means air sits at the outlet while the coil is off; energising the DC12V coil shuts the supply and vents the outlet to exhaust. That makes it the natural pick where a machine must keep receiving air when control power is lost - a fail-to-feed behaviour no normally closed valve can give. The 3/8in port leaves headroom for a larger spring-return cylinder than an M5 or 1/8in body would.
This is a genuine AirTAC part. Across the 3V1, 3V2 and 3V3 ranges the same 3/2 function is offered normally closed as well as normally open, in AC220V, DC24V, AC110V, AC24V and DC12V coils, with DIN plug or flying-lead entry, and with manifold bases that carry several valves on one shared supply. Pressure, flow and coil-power figures are not printed on this page; send the SKU by RFQ and we will read them off the datasheet for you.

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.
A spring-extended stopper on a filler infeed stays up through a power cut, holding bottles safely; energising the DC12V coil vents the line and lets the spring retract it.
An air knife over a green-lumber conveyor that blows continuously until the coil is energised to stop it - the right default where a jet must stay on for belt cleaning.
DC12V coils suit vehicle battery supplies, and the normally open feed keeps a tailgate lock cylinder engaged even with the engine switched off.
Your first decision is the fail-safe direction: this SKU is normally open, so the outlet keeps its air when power drops; choose the NC variant of the same body if the actuator must instead go to exhaust. Next, the coil: DC12V matches mobile and battery-backed panels, and the flying-lead entry arrives pre-wired, saving the DIN socket wiring step. A 3/8in port suits a bigger single-acting actuator; step down to 1/8in or 1/4in on smaller jobs. Because we hold no published flow data for this series, ask us to confirm sizing against your cylinder before ordering - and if you need figures printed today, the documented AirTAC 3V2 and 3V3 valve bodies carry published flow and coil-power specifications. A double-acting cylinder needs a 5-port valve, which is the 4V series, not this one.
Confirm before you order
Pressure range, flow, coil power, response time and temperature limits are not printed on this page. Quote the SKU in an RFQ and we will confirm each figure from the AirTAC datasheet. If you need published numbers before you enquire, the 3V2 and 3V3 bodies are the documented alternatives in this family.
No. A 3/2 valve has one outlet, so it can only feed or vent a single-acting, spring-return actuator. For a double-acting cylinder you need a 5-port valve - the AirTAC 4V series covers that.
