Airtac 3V2M Solenoid Valve 3V2MNCB-8F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCB-8F 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.

About the Airtac 3V2M Solenoid Valve 3V2MNCB-8F
Eight NC 3/2 valve bodies on one dedicated 8F base make the 3V2MNCB-8F a compact switching block for spring-return circuits. Direct-acting poppets with spring return keep the outlet vented until each DC24V coil is energised, and the shared supply and shared wiring mean one air connection and one cable run for all eight stations.
Power is the figure to plan around here: 7.0 W per DIN plug coil means 56 W, roughly 2.3 A at 24 V, when every station is held energised - size the PSU for that worst case. Each stage flows Cv 0.1 across 0-0.8 MPa, protection is IP65 (DIN 40050), and PT1/8 is standard (G or NPT to order).

What a 3/2 Valve Does
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.
Where the Airtac 3V2M Solenoid Valve 3V2MNCB-8F Is Used
End-of-line test rig with eight vent stations
Eight NC valves vent eight product ports in sequence; centralised exhaust keeps one silenced outlet on the rig frame.
Register control on a printing press
Use individual stations to feed or vent spring-return register rollers, with the manual override aiding web set-up.
Divert gates on a packaging sorter
NC valves hold gates vented between shots, so a control fault stops the sorter in a known, safe state.
Is the Airtac 3V2M Solenoid Valve 3V2MNCB-8F the Right Part?
At Cv 0.1 this eight-station block trades some flow for density; stations needing more should take an individual 3V2 valve (Cv 0.18 at 1/8 in, 0.19 at 1/4 in, vacuum-rated) or a 3V3 (Cv 0.62 at 1/4 in). If the duty is light and power is the constraint, 3V1 at 3.0 W DC halves the coil load per point.
Fix five choices at order time: NC initial state, DC24V, DIN plug entry, eight stations, centralised exhaust. The NC function cannot be reworked after purchase - the dedicated base gasket converts nothing. Driving double-acting cylinders? Move to the AirTAC 4V series.
Confirm before you order
- ✓ Port size and thread (PT from stock; G / NPT to order)
- ✓ Initial state — NC or NO, ordered up front
- ✓ Coil voltage matches your controller output
- ✓ Electrical entry — DIN plug or flying lead
- ✓ Single valve, bare base, or complete assembly
- ✓ Single-acting duty, not double-acting
Installation & Wiring Notes
- check Use clean air filtered to 40µm or finer.
- check Stay within 0-0.8 MPa (0-114 psi) operating pressure.
- check Match the coil voltage to your controller output.
- check Use the manual override to test before powering up.
- check Leave the exhaust port clear, or fit a silencer.
- check Blank any unused station on the base before pressurising.
- check Wiring by qualified personnel, per AirTAC documentation.
Airtac 3V2M Solenoid Valve 3V2MNCB-8F FAQ
Eight NC 3/2 direct-acting poppet valves, single solenoid, spring return, on a shared 8F base. Cv 0.1 per station, 0-0.8 MPa (0-114 psi), -20 to 70 C, DC24V coils at 7.0 W each, IP65 (DIN 40050), PT1/8, centralised exhaust. Air filtered to 40 um or finer.
Every 3V2M DC coil takes 7.0 W, so eight energised stations draw 56 W - about 2.3 A at 24 V. Add a margin for future stations before choosing the power supply. The coil count, not the base, sets this figure.
