Airtac 3V2M Solenoid Valve 3V2MNCB-6F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCB-6F 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-6F
Six spring-return 3/2 NC valves on one base: 3V2MNCB-6F gives you six independent on/off air outputs from a single PT1/8 supply and a single wiring run. The coaxial poppet construction seats well, and each direct-acting DC24V coil draws 7.0 W, so a worst-case all-on figure of about 42 W, near 1.75 A at 24 V, should shape your power supply choice.
Exhaust from all six stations is centralised through the base, keeping piping tidy. Flow is Cv 0.1 per station, temperature range -20 to 70 C, and coil protection IP65. The normally closed state is chosen at order and cannot be reversed afterwards by flipping the dedicated base gasket or by any other field method.

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-6F Is Used
Ejector pins on an injection mould
Six spring-return ejector or core-pull cylinders on an injection mould tool, sequenced from one 6-station manifold.
Press brake clamps
Quick-action clamps on a press brake that release the sheet the instant power is lost, since the NC valve vents the outlet.
Paint booth purge valves
Purge-air valves in a paint booth interlock, all venting to a safe state through one centralised exhaust.
Is the Airtac 3V2M Solenoid Valve 3V2MNCB-6F the Right Part?
Five points to lock in: state NC (ordered once, unchangeable afterwards - reversing the base gasket does not convert it), voltage DC24V, entry DIN plug, station count 6, exhaust centralised, and thread PT standard with G or NPT as order options. Cv is 0.1 per station through the base; for a higher-flow station, an individual 3V2 offers Cv 0.18 at 1/8 and 0.19 at 1/4 (vacuum rated), 3V3 offers Cv 0.62 at 1/4 (vacuum rated), and 3V1 cuts coil power to 3.0 W DC.
Double-acting cylinders need five ports, not three - route that requirement 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-6F FAQ
Per valve: Cv 0.1, 0-0.8 MPa (0-114 psi) operating pressure, -20 to 70 C temperature, PT1/8 ports, IP65 (DIN 40050). Coil power is 7.0 W at DC24V - about 42 W if all six run at once (AC coils in the family are 7 VA). Supply air filtered to 40 um or finer; no lubrication needed.
They are 3/2 valves with three ports, so they drive single-acting spring-return cylinders, blow duty and pilots - not double-acting cylinders, which need a 5-port valve from the AirTAC 4V series. Also note the NC state is ordered, not converted: reversing the dedicated base gasket does not change NC to NO.
