The AirTAC AirTAC 3V310-08 Solenoid Valve, 3V300 Series (3V31008NC-X0) 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.
The 3V31008NC is the same 3-port, 2-position function written without separators: supply, outlet and exhaust, two states, normally closed, on a 1/4in PT port. Until the coil is energised the outlet stays vented, which is the behaviour you want wherever loss of control power must leave a cylinder retracted or a jet shut. The code carries no voltage letter, so the coil voltage is chosen when you order.
This is a genuine AirTAC part with DIN plug entry. The wider family spans NC and NO states, five coil voltages, flying-lead or DIN entry, and 3V-F manifold bases. Pressure, flow and coil power are not listed here; we will supply them from the datasheet against your RFQ.

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 single-acting cylinder on a tail-lift or dock leveller that must lower under spring force whenever control power is cut.
A single-acting clamp on a small bench press jig, where the operator wants air delivered only while a foot switch is held down.
Venting an air spring or pneumatic counterbalance on a test rig the instant control power is lost, so the rig settles safely.
Everything after the body code is a choice you make: 08 is the 1/4in port, NC is the normally closed state, and the missing voltage letter means you pick AC220V, DC24V, AC110V, AC24V or DC12V when ordering. PT thread is the standard on this family; G and NPT are catalogue options to order. Since we hold no published flow data for the 3V1x0/3V2x0/3V3x0 group, ask us to confirm sizing against your actuator before you commit - or, if printed figures are a requirement today, the separately documented 3V2 and 3V3 port-coded bodies publish theirs. A double-acting cylinder is a job for the 5-port AirTAC 4V series.
Confirm before you order
Not on this page. Send the RFQ and we confirm them from the AirTAC datasheet before you commit to the order. Buyers who need figures printed on the product page itself can use the separately documented 3V2 and 3V3 port-coded bodies instead.
The code carries no voltage letter, so it is specified at order - the family offers AC220V, DC24V, AC110V, AC24V and DC12V, and the coil cannot be converted later by rewiring. Tell us your panel supply and we will note the right coil on the RFQ.
