Airtac 3V2M Solenoid Valve 3V2MNCEI-4F
The AirTAC Airtac 3V2M Solenoid Valve 3V2MNCEI-4F 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 3V2MNCEI-4F
The 3V2MNCEI-4F is a complete four-station manifold: four 3/2 NC valve bodies pre-mounted on a shared 3V2M base. Normally closed means each outlet stays vented and passes no air until its coil is energised, so a de-energised machine is a safe machine on this bank. Every valve is direct acting with a single solenoid and spring return, built around a coaxial poppet that shuts off cleanly.
Because the bodies sit on one dedicated base, the whole bank draws from a single PT1/8 supply and one wiring run, and fault-finding moves station by station instead of valve by valve. Each AC110V coil takes 7 VA, so the fully energised worst case is 28 VA - size the control transformer for that. A manual override on every body helps you prove plumbing before power-up.

Model Code: Airtac 3V2M Solenoid Valve 3V2MNCEI-4F
| 3V2M | Body — sets the flow, the coil power and whether vacuum is rated. |
|---|---|
| 1/8 in | Port size. M5, 06 = 1/8 in, 08 = 1/4 in, 10 = 3/8 in. |
| NC | Normally closed: no air at the outlet until the coil is energised. |
| AC24V | Coil voltage. A = AC220V, B = DC24V, C = AC110V, E = AC24V, F = DC12V. |
| I | Electrical entry: I = flying lead, otherwise a DIN plug. |
| 4F | 4 stations in one assembly, centralised exhaust. |
| PT | Port thread. PT ships from stock; G and NPT are available to order. |
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 3V2MNCEI-4F Is Used
Pick-and-place gripper bank
Four NC valves vent four suction or gripper circuits until commanded, so a dropped part cannot be held by a pressurised circuit after an E-stop.
Rotary indexing table clamps
Each station's clamp fixture gets its own 3/2 output from the shared base, keeping four clamp circuits on one supply and one wiring run.
Benchtop leak-test rig
Test chambers stay open to exhaust between cycles; energising the coil applies air only during the measured test window.
Is the Airtac 3V2M Solenoid Valve 3V2MNCEI-4F the Right Part?
This assembly is the density play: Cv 0.1 per valve keeps ports tight so four stations fit where individual valves would not. When one circuit needs more flow, fit an individual 3V2 instead (Cv 0.18 at 1/8 in, 0.19 at 1/4 in, and vacuum rated); step to 3V3 (Cv 0.62, 1/4 in) for the highest flow in the family, or to 3V1 at 3.0 W DC when coil draw matters most.
Confirm these points before ordering: NC initial state, AC110V coil, flying-lead entry, four stations, centralised exhaust, PT thread (G and NPT are catalogue options). The NC/NO choice is fixed at the factory - the dedicated base gasket cannot be reversed to convert the state later. Double-acting cylinders need the 5-port AirTAC 4V series, not this valve.
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 3V2MNCEI-4F FAQ
Each valve: 3/2 normally closed, direct acting, spring return, Cv 0.1, PT1/8 port, operating pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, AC110V coil at 7 VA, protection IP65 (DIN 40050), manual override fitted. Air must be filtered to 40 um or finer; lubrication is not required.
No. The 3V2M NC and NO versions use a dedicated base gasket, and reversing that gasket does not convert the state. Initial state is set at order time, so specify NC or NO when you buy; if a circuit later needs NO action, order a 3V2MNO valve body for that station.
