The AirTAC AirTAC 3V106B-14 Solenoid Valve, 3V1 Series (3V106B14F) 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.
A 14-station 3V106B14F puts fourteen AirTAC 3V1 direct-acting 3/2 valves behind one panel cutout. Every station is a three-port, two-state device: it either pressurises its outlet or dumps it to exhaust - the switching pattern behind single-acting cylinders, clamping fixtures, air blow and pilot signals.
The DC24V coils are the power story here - 3.0 W each, roughly 42 W across fourteen stations, comfortably inside a modest 24 V PSU budget. Ports are 1/8in PT with IP65 coils (DIN 40050), and each valve's manual override helps during commissioning. AirTAC supplies the valve in a single fixed initial state, stated on the datasheet.

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.
Fourteen single-acting stopper cylinders hold or release totes, each triggered by its own station on the shared base.
Spring-return swing clamps clear the robot path between screws; one small valve per clamp keeps wiring to a single 24 V drop.
Each station routes flush air to one reagent channel; 40 um filtered instrument air and no lubrication keeps the lab supply simple.
Work through the ladder before buying fourteen stations. 3V1 is the smallest body and lists no Cv, so flow-hungry circuits should step up to 3V2 (1/8in or 1/4in, NC or NO selectable, Cv 0.18-0.19, vacuum rated) or 3V3 (1/4in, Cv 0.62); 3V2M is the pick when manifold density beats flow. Any double-acting cylinder needs a 5-port valve - the AirTAC 4V series.
Ordering checklist for this code: 1/8in PT ports (G and NPT exist as catalogue options), DC24V coils at 3.0 W, DIN plug entry, and a fourteen-station manifold assembly. Keep air filtered to 40 um or finer; lubrication is unnecessary. Flow-critical duties carry no published Cv, so raise them in your RFQ.
Confirm before you order
Pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, IP65 (DIN 40050). DC24V coils take 3.0 W each - about 42 W for fourteen. Elsewhere in the 3V1 family: AC220V 4.5 VA, AC110V 4.5 VA, AC24V 5.0 VA and DC12V 2.5 W. AirTAC publishes no Cv for 3V1.
No. A 3/2 valve has three ports and two states - it feeds or vents one line - so it matches single-acting cylinders, air blow, clamps and pilot duty. Double-acting cylinders need pressure on both sides, which is the job of a 5-port valve like AirTAC's 4V series.
