Airtac 3V2M Solenoid Valve 3V2MNCB-19F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCB-19F 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-19F
Nineteen normally closed 3/2 valves ride on a single 3V2M base in this assembly, sharing one PT1/8 air feed and one DIN-plug wiring loom at DC24V. Every valve is a direct-acting poppet unit with spring return: energise a coil to feed its outlet, drop the coil and the spring seats the poppet, venting the outlet to the centralised exhaust gallery.
Two engineering numbers decide whether this suits your panel. First, flow: Cv 0.1 per station, lower than a stand-alone 3V2 because the path runs through the base. Second, the worst-case load: nineteen coils at 7.0 W is 133 W, near 5.5 A on a 24 V rail, so size the PSU and DIN-rail wiring for an all-on condition, not the typical few-coils-on case.

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-19F Is Used
Dosing-skid pilot switching
Nineteen pilot lines on a chemical dosing skid are each opened by one station, with the NC layout venting every pilot the moment the skid is shut down.
Analyser sample-deck actuation
An automated analytical instrument uses single-acting air pistons to divert sample probes; one 3V2M station per probe keeps control wiring to a single 24 V run.
Assembly-cell part ejection
Nineteen eject stations along an assembly line blow or push finished parts off their nests, each firing only while its coil is energised.
Is the Airtac 3V2M Solenoid Valve 3V2MNCB-19F the Right Part?
A normally closed bank like this is the right default wherever a power failure should leave the machine vented and safe - outlets pass air only while the coil is held. Remember that NC and NO are order-time decisions on 3V2M; there is no field conversion, and turning the base gasket around achieves nothing. If one duty outgrows the base, run an individual 3V2 (Cv 0.18 at 1/8, 0.19 at 1/4, vacuum-rated) or a 3V3 (Cv 0.62, 1/4, vacuum-rated) in that circuit, and pick 3V1 (3.0 W DC) for low-power duties.
Confirm five things at ordering: NC state, DC24V, DIN plug entry, nineteen stations, centralised exhaust, plus thread (PT as standard; G or NPT are catalogue options). Double-acting cylinders fall outside 3/2 function - specify the AirTAC 4V series instead.
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-19F FAQ
Nineteen NC 3/2 stations on one base, PT1/8 port, Cv 0.1 flow coefficient per station, 0-0.8 MPa operating pressure, -20 to 70 C fluid temperature, DC24V coils drawing 7.0 W each (133 W worst case), IP65 (DIN 40050) protection. Air must be filtered to 40 um or finer; lubrication is not required.
With centralised exhaust every station vents into one shared gallery and one silencer point, which keeps the machine exterior tidy and cuts noise hardware. The trade-off is that exhaust air from all nineteen valves mixes, so if you need to capture, monitor or separately silence individual station exhausts, order the -D independent-exhaust version instead. Note that a 3/2 valve drives single-acting cylinders only; double-acting actuators need the AirTAC 4V series.
