The AirTAC AirTAC 3V210-08NC Solenoid Valve 3/2 NC 1/4in NPT DC24V 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.
A 3/2 solenoid valve has three ports - supply, outlet and exhaust - and two positions, so at any moment it either feeds air to the outlet or vents the outlet to exhaust. This SKU is the normally closed version: with the coil de-energised the outlet is closed and vented, and air only reaches your actuator or outlet line while the coil is energised. That makes it a natural fail-safe choice, because a power cut or an emergency stop drops the outlet back to exhaust. The 1/4in port gives you a step up from the 1/8in size, suited to a larger single-acting cylinder or a bigger blow line, and the NPT thread matches North American pipework and fittings.
We carry this part as a genuine AirTAC valve and ship it as coded: DC24V coil, DIN plug electrical entry, NPT thread. Across the wider family you can also order the normally open state, other coil voltages (AC220V, AC110V, AC24V and DC12V), flying-lead entry, and 3V-F manifold bases for multi-valve installations. Anything you need verified - pressure range, flow, coil power, protection rating - we will read straight off the datasheet and confirm on request.

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.
Energise to clamp a workpiece with a single-acting spring-return cylinder; de-energise or lose power and the 3/2 vents the clamp side, letting the spring release. NC behaviour keeps the fixture in a defined vented state between cycles.
A 1/4in port feeds an air nozzle that clears rinse water or dust from bottle necks before filling. The valve gives clean on/off air at the station and exhausts the downstream line the moment the coil drops out.
Use the 3/2 to switch the control line to a bigger pneumatically actuated valve on a water treatment or food plant skid, so a single DC24V panel signal governs a much larger air consumer.
Choose this code when three things line up. First, the fail-safe direction: normally closed means no air at the outlet until you energise the coil, so the machine stays vented on power loss - if your safety case needs the opposite, order the NO variant of the same body. Second, the port: 1/4in NPT suits a larger single-acting spring-return actuator than the 1/8in and M5 sizes; the family also steps up to 3/8in. Third, the coil: DC24V must match your panel supply, because a solenoid coil is wound for its voltage and cannot be converted by rewiring - the same valve is offered for AC220V, AC110V, AC24V and DC12V. The DIN plug entry means you fit a connector on site; the suffix-I flying-lead version arrives pre-wired if that suits your loom better.
One honest caution before you order: published flow figures for this family are not in our hands, so send us your actuator details and we will confirm sizing against the datasheet before you commit. If you want a fully specified 3-port valve today, the documented AirTAC 3V2 (1/8in and 1/4in) and 3V3 (1/4in) bodies carry published flow and coil-power figures. And remember the rule of function: a 3/2 valve cannot drive a double-acting cylinder - that job needs a 5-port valve from the AirTAC 4V series.
Confirm before you order
We hold no published figures for this family on this page, and we will not guess them. Tell us your application via the RFQ and we will confirm the pressure range, flow, coil power, protection rating and temperature limits directly from the AirTAC datasheet. If you need those numbers published today rather than confirmed, the documented AirTAC 3V2 (1/8in and 1/4in) and 3V3 (1/4in) bodies are the 3-port valves with full published figures.
No - a double-acting cylinder needs air to both sides alternately, which takes a 5-port 4-position-relevant valve such as the AirTAC 4V series. A 3/2 valve feeds one outlet or vents it, so it belongs with single-acting spring-return cylinders, blow lines and control-signal switching. On the state: pick NC if the outlet must be vented and dead when power is lost; pick NO if it must stay supplied through a power failure. The same body is available in both states in this family.
