Airtac 3V2M Solenoid Valve 3V2MNCA-20F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCA-20F 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 3V2MNCA-20F
Twenty 3/2 NC poppet valves, all direct-acting with spring return, ride on a single 20F base in the 3V2MNCA-20F. One PT1/8 inlet charges the whole manifold, and one DIN wiring strip powers all twenty AC220V coils - the densest configuration this family offers.
Plan the electrics around the arithmetic: 7 VA per coil means roughly 140 VA if every station energises at once, so your control transformer should handle that peak. Stations combine and expand freely, and the valve count can even be mixed with other 3V2M types on the same block. Exhaust is centralised through one common port. Every station stays closed until its coil is energised, an NC condition set at the factory that no gasket reversal or field trick can alter.

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 3V2MNCA-20F Is Used
Carousel assembly machine
Twenty single-acting clamp stations around a rotary indexing table run off one manifold, so a station change means swapping a valve, not re-piping the cell.
Can-line reject ejectors
A high-speed can line with twenty ejector fingers vents instantly whenever a coil drops out, exactly the fail-safe behaviour the NC state provides.
PCB test fixture array
Twenty spring-return test pins on an electronics fixture press and release in programmed groups, all switched from one consolidated air and wiring point.
Is the Airtac 3V2M Solenoid Valve 3V2MNCA-20F the Right Part?
At Cv 0.1 each of the twenty paths concedes flow to the base architecture. A station that must move more air deserves an individually ported 3V2 - Cv 0.18 at 1/8 in and vacuum rated - or the 3V3 at Cv 0.62 for 1/4 in duty (vacuum rated too). Where a task is light and coil heat matters, 3V1 sips 3.0 W on DC. Double-acting cylinders remain the domain of the 5-port AirTAC 4V series, never a 3/2 valve.
Verify five things against your design: NC initial state (fixed for life), AC220V coil, DIN plug entry, 20-station count, centralised exhaust. PT is the standard thread on the 3V2M family, with G and NPT available as options you specify when ordering.
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 3V2MNCA-20F FAQ
20-station 3/2 NC assembly on a 3V2M base, PT1/8 ports, Cv 0.1 flow coefficient, pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, AC220V coils at 7 VA each (about 140 VA all energised), IP65 protection to DIN 40050, air filtered to 40 um or finer.
Centralised exhaust, as on this 20F version, sends all twenty stations to one common port - fewer pipes, simpler routing. Independent exhaust (the D option) gives each station its own port, useful when a hot or oily station must not contaminate the shared line. The choice is made at ordering; the block cannot be re-plumbed afterwards. PT is the standard thread, with G and NPT as order options.
