Airtac 3V1 Solenoid Valve 3V1M5C
The AirTAC Airtac 3V1 Solenoid Valve 3V1M5C is a genuine 3-port 2-position (3/2) solenoid valve with M5 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 3V1 Solenoid Valve 3V1M5C
The 3V1M5C is an individual AirTAC 3V1 valve with an M5 port and an AC110V coil. It is a 3/2, direct-acting, single-solenoid valve with spring return: when energised the outlet is fed, and when power drops the spring shifts it back so the line exhausts. Use it to feed or vent one line - a small spring-return actuator, an air jet, a clamp or the pilot stage of a bigger valve.
On AC110V the coil draws just 4.5 VA, so it can sit on a standard control-circuit transformer without disturbing the rest of the panel. It plugs into a DIN socket, so coil replacement means unplugging a connector rather than unwiring terminals. Construction is rated IP65 (DIN 40050). The valve is supplied in a single fixed initial state - confirm it on the datasheet before wiring your circuit. Every unit ships as genuine AirTAC product with datasheet support.

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 3V1 Solenoid Valve 3V1M5C Is Used
Bottle-guide clamping
A small spring-return clamp cylinder holds bottles against the guide rail on a filling line, releasing the instant the AC110V coil de-energises and the valve vents.
CNC mist blow-off
Between cuts on a CNC lathe, a short M5 air jet clears coolant mist and chips from the tool tip, with the coil drawing only 4.5 VA from the machine's control transformer.
Chemical dosing pilot
The valve sends an intermittent pilot signal to a larger diaphragm valve on a dosing skid, opening and closing the process line from the 110V control circuit.
Is the Airtac 3V1 Solenoid Valve 3V1M5C the Right Part?
Because 3V1 is the smallest body in the family and carries no published Cv, treat flow-critical M5 duties as a question to settle with us first. If the circuit demands more air, move up to 3V2, offered in 1/8" and 1/4" with NC or NO selectable function and Cv 0.18-0.19, or to the 1/4" 3V3 at Cv 0.62; 3V2M is the pick where manifold density beats raw flow. Remember that a double-acting cylinder calls for a 5-port valve from the AirTAC 4V range.
Match five things to your circuit before ordering: the M5 port, the absence of a separate thread code on M5, the AC110V coil, the DIN-plug entry (a flying-lead version exists), and whether a single valve is right or a manifold assembly would suit better.
Confirm before you order
- ✓ Port size and thread (PT from stock; G / NPT to order)
- ✓ 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 Wiring by qualified personnel, per AirTAC documentation.
Airtac 3V1 Solenoid Valve 3V1M5C FAQ
Pressure 0-0.8 MPa (0-114 psi); temperature -20 to 70 C; medium is air filtered to 40 um or finer, with no lubrication required. Coil powers in the 3V1 range are AC220V 4.5 VA, AC110V 4.5 VA, AC24V 5.0 VA, DC24V 3.0 W and DC12V 2.5 W, so this AC110V version draws 4.5 VA. Rating is IP65 (DIN 40050). AirTAC publishes no flow coefficient or effective area for 3V1 - verify flow suitability from the datasheet or via our RFQ desk.
It runs on a common 110V control supply at 4.5 VA, a load small enough for most panel transformers, and connects through a DIN plug so it can be swapped without touching screw terminals. If your panel is DC instead, the same M5 valve exists as 3V1M5B (DC24V, 3.0 W) or 3V1M5F (DC12V, 2.5 W). Keep in mind it performs a 3/2 feed-and-exhaust function only - single-acting loads, never double-acting cylinders.
