Airtac 3V2M Solenoid Valve 3V2MNCB-17F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCB-17F 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-17F
The 3V2MNCB-17F is the flow-versus-density decision made explicit: seventeen 3/2 normally closed valves share one 3V2M base, DC24V coils, DIN plug entry, centralised exhaust, PT1/8 threads. Each station is a direct-acting, single-solenoid, spring-return poppet valve with a flow coefficient of Cv 0.1 - lower than a standalone 3V2 because the air path runs through the base. In exchange you get seventeen switch points in one compact block, fed by a single supply.
That manifold density also consolidates wiring: one harness serves all seventeen coils, cutting panel space and making each fault a station-level lookup. Manual override assists commissioning and IP65 (DIN 40050) protects the coils. A 17-station all-on draw is about 119 W at DC, near 5 A at 24 V - check your supply. NC cannot be converted to NO afterwards; the dedicated base gasket cannot be reversed to change state.

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-17F Is Used
Welding jig clamp array
Seventeen NC stations each hold one spring-return clamp on a car-body welding jig, all released the moment control power drops.
CNC chip-blow stations
Seventeen on/off air jets clear chips from machining zones in sequence, fed from one regulator and vented through one exhaust.
Trailer brake interlock pilots
Pilot-air switching on dock and trailer handling equipment, with seventeen interlock points controlled from a single DC24V harness.
Is the Airtac 3V2M Solenoid Valve 3V2MNCB-17F the Right Part?
Confirm five parameters against your schematic: initial state (NC), coil voltage (DC24V), electrical entry (DIN plug), station count (17F) and exhaust type (centralised; the D code gives per-station exhaust), plus thread (PT standard, G or NPT to order). The NC/NO state cannot be changed after purchase by flipping the gasket or any other means.
Size each station by flow, not just count: at Cv 0.1, 3V2M suits short-run clamps, pilots and blow duties. A station moving more air deserves an individual 3V2 (Cv 0.18 at 1/8 in, Cv 0.19 at 1/4 in, vacuum-rated) or a 3V3 (Cv 0.62, 1/4 in, vacuum-rated), and 3V1 (3.0 W on DC) is the economy choice for light duty. If any actuator is double-acting, that circuit needs the AirTAC 4V 5-port 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-17F FAQ
17-station 3/2 NC assembly, direct-acting, single solenoid, spring return, coaxial shut-off. Cv 0.1 per station, operating pressure 0-0.8 MPa, medium temperature -20 to 70 C, DC coil power 7.0 W per station (about 119 W all-on), protection IP65 (DIN 40050), PT1/8 ports, centralised exhaust, manual override fitted.
Cv 0.1 is a flow coefficient, not a flow rate, and it reflects the path through the base. Use 3V2M where station count matters most. Pick an individual 3V2 (Cv 0.18 at 1/8 in, Cv 0.19 at 1/4 in, also vacuum-rated) or a 3V3 (Cv 0.62, 1/4 in, vacuum-rated) for flow-hungry positions, and 3V1 at 3.0 W DC for low-power small duties. Note that no 3-port valve, including this one, can drive a double-acting cylinder - that calls for the AirTAC 4V series.
