Airtac 3V2M Solenoid Valve 3V2MNCB-15F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCB-15F 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-15F
The 3V2MNCB-15F is a complete 15-station manifold assembly: fifteen 3/2 normally closed valve bodies, each with a DC24V coil on a DIN socket connection, factory combined on one shared 3V2M base with a PT1/8 supply port. Every valve is direct-acting with spring return and a coaxial shut-off poppet, so the outlet stays vented until its coil is energised and each station returns to the closed state on its own spring when power is lost.
Because all fifteen stations share one air supply and one wiring loom on the base, installation is a single plumbing run instead of fifteen separate valves, and a fault can be isolated station by station. Each DC24V coil draws 7.0 W, so a fully energised 15-station assembly pulls roughly 105 W, about 4.4 A at 24 V - size the power supply for that worst case. The body is rated IP65 (DIN 40050) and a manual override on each valve helps during commissioning.

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-15F Is Used
Automated assembly cell with spring-return clamps
Fifteen single-acting clamp cylinders hold small housings in a fixture. One DC24V manifold energises each clamp in sequence, and a power cut drops every clamp open safely by spring return.
Bottling line air-ejection nozzles
Each station fires a short burst of air to push a tilted bottle back onto the conveyor. The shared base feeds all fifteen nozzles from one PT1/8 supply instead of fifteen separate valves and harnesses.
Textile machine individual yarn cutters
A winding frame with fifteen cutter positions vents each cutter outlet through the centralised exhaust. Blowing one station means replacing one body on the shared base, not rewiring the machine.
Is the Airtac 3V2M Solenoid Valve 3V2MNCB-15F the Right Part?
Choose the 3V2MNCB-15F when you need fifteen 3/2 stations packed onto one manifold and each station only needs Cv 0.1. The flow path runs through the base, so if any single station needs more flow, step that station up to an individually ported 3V2 valve (Cv 0.18 at 1/8 in, 0.19 at 1/4 in) or a 3V3 (Cv 0.62, 1/4 in); where the duty is small and coil draw matters most, the 3V1 series runs at just 3.0 W on DC. Note that normally closed here means exactly that at order time: the NC state is built into the valve and cannot be converted afterwards, and reversing or flipping the base gasket does not change it.
Before ordering, match five points: initial state (NC as this SKU), coil voltage (DC24V), electrical entry (DIN plug), station count (15F) and exhaust type (centralised on this version, independent D available to order). PT is the standard thread and G or NPT are order options - confirm from the datasheet if your pipework needs them. If the actuator is a double-acting cylinder, this 3/2 assembly is the wrong tool; a 5-port valve from the AirTAC 4V series is what you need.
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-15F FAQ
It is a 15-station 3/2 normally closed manifold assembly with DC24V coils (7.0 W each; AC versions draw 7 VA). Flow coefficient is Cv 0.1, operating pressure 0-0.8 MPa (0-114 psi), temperature range -20 to 70 C, protection IP65 (DIN 40050). The medium is air filtered to 40 um or finer and lubrication is not required. Ports are PT1/8 and each valve has a manual override.
No. The NC initial state is fixed when the 3V2M valve is made; the catalogue states that reversing the dedicated base gasket does not convert NC to NO, so order NO explicitly if your circuit needs it. Each 3/2 valve has three ports and two positions - it feeds the outlet or vents it - so it drives single-acting spring-return cylinders, blow-off, clamping and pilot duty. A double-acting cylinder needs a 5-port valve from the AirTAC 4V series instead.
