The AirTAC Airtac 3V2M Solenoid Valve 3V2MNOC-10F 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.
This 3V2MNOC-10F arrives as a built ten-station bank from AirTAC's 3V2M family: ten normally open 3/2 valve bodies matched to a 10F base with centralised exhaust, every coil taking AC110V through a DIN plug. Each station is a direct-acting, single-solenoid, spring-return valve of coaxial poppet construction, rated Cv 0.1 on a PT1/8 path.
Normally open behaviour means each outlet feeds air while its coil is off and vents to the common exhaust when energised - the right default where a machine must act or blow with power absent. One catalogue caution applies: the initial state is decided at order time. Reversing the dedicated base gasket does NOT convert NO to NC, so buy the state you need.

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.
Spring-return divert cylinders along a glass-bottle conveyor must sit up between cycles. Each normally open 3/2 station vents its pin only when the AC110V coil energises, while the single 10F base gives the whole pin bank one PT supply point and one shared exhaust route.
Chip-clearing and part-cooling jets around a machining centre should flow air by default rather than depend on a powered signal. The ten Cv 0.1 stations each run a small jet, and because supply and wiring are unified on the base, a dead station is traced from one access point.
A rotary filling machine keeps ten spring-return lid clamps retracted until each chuck is seated. The normally open state holds clamps open with power off, the AC110V coils draw 7 VA apiece - about 70 VA with all ten energised - and the manual override on each body aids chuck-by-chuck setup.
Pick 3V2M when packing stations matters more than per-station flow: the path runs through the base, giving Cv 0.1 here versus the individually-ported 3V2's Cv 0.18 at 1/8 in and 0.19 at 1/4 in (the 3V2 is also vacuum-rated). Step to 3V3 (Cv 0.62, 1/4 in) for the strongest flow in the 3V range, or to 3V1 (3.0 W DC) when coil draw is the constraint. A double-acting cylinder is beyond any 3-port valve - specify the 5-port AirTAC 4V series for that. Match five points when ordering: initial state (NO here, unchangeable after purchase), coil voltage (AC110V, 7 VA), electrical entry (DIN plug; add I for flying lead), station count (10F) and exhaust (centralised here; D for independent). Thread is PT as standard, with G and NPT available to order.
Confirm before you order
Each of the ten stations is a normally open 3/2 valve with flow coefficient Cv 0.1, operating pressure 0-0.8 MPa (0-114 psi), temperature range -20 to 70 C, AC coil power of 7 VA at AC110V, and IP65 (DIN 40050) protection. Medium is air filtered to 40 um or finer with no lubrication needed, and every valve body carries a manual override for commissioning.
No. The NO state is chosen when the valve is ordered and is built into the valve body, not the base. AirTAC states plainly that reversing or flipping the dedicated base gasket does not convert the state, and no field method exists. If a station must stay closed until energised, order that station in the equivalent NC code instead.
