The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCF-13F is a genuine 3-port 2-position (3/2) solenoid valve with 1/8 in ports. It either feeds its outlet or vents it to exhaust, which is what makes it the valve for single-acting cylinders, on/off air blow, clamping, vacuum switching and pilot duty.
The 3V2MNCF-13F packs thirteen normally closed 3/2 valves onto one AirTAC base, all direct-acting, single-solenoid and spring return, with a coaxial shut-off poppet that seals well cycle after cycle. Ports are PT1/8 and the flow coefficient per station is Cv 0.1. Nothing moves to the outlet until the relevant 12 V coil is energised.
Thirteen separately plumbed valves can be slow to troubleshoot; here, one shared supply and one wiring run mean a dead circuit is traced station by station in minutes, and different valve types can sit side by side on the same manifold. Budget 13 x 7.0 W = 91 W for a fully energised bank, about 7.6 A at 12 V. The exhaust is centralised, leaving through a common base port.

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.
Thirteen spring-return clamps grip fill heads on a rotary bottler; each NC station vents to the safe open state the moment its coil drops out.
A metrology bench uses isolated 3/2 channels to switch pilot air to one gauge circuit at a time without cross-bleeding between stations.
Normally closed valves hold interlock latches released only while powered, so a control failure leaves every door free to return to its safe state.
This code fixes five choices for you: NC state, DC12V coils, DIN plug entry, a 13-station base and centralised exhaust. Thread is PT by default, with G and NPT available to order.
If any single station needs more than Cv 0.1, mount an individual 3V2 beside the bank (Cv 0.18 at 1/8 inch, 0.19 at 1/4 inch, and vacuum-rated) or a 3V3 at Cv 0.62 for the highest flow in the range. Small duties can drop to 3V1 at 3.0 W DC. Remember the NC/NO state is permanent once purchased, and double-acting cylinders call for the AirTAC 4V series.
Confirm before you order
Thirteen NC 3/2 stations, Cv 0.1 per station, 0-0.8 MPa operating pressure, -20 to 70 C temperature, 7.0 W per DC12V coil (91 W all on), IP65 protection, PT1/8 ports, spring return, direct-acting coaxial poppet construction, 40 um maximum air filtration.
This assembly vents all thirteen stations through one common base port, which keeps tubing short and silencing simple. Choose the D (independent exhaust) variant instead when a station must not see back-pressure from others, for example where exhaust speed affects cylinder return time.
