Airtac 3V1 Solenoid Valve 3V1M5B8F
The AirTAC Airtac 3V1 Solenoid Valve 3V1M5B8F 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 3V1M5B8F
The 3V1M5B8F places eight 3/2 direct-acting stations on one M5 manifold. Because each DC24V coil draws only 3.0 W, the whole assembly stays a light load for a small 24 V supply even when several positions are energised together.
Each station is single-solenoid with spring return, feeding or venting one line, so the block fits single-acting clamp cylinders, air-blast duties and pilot stages. Coil housings carry an IP65 (DIN 40050) rating and every valve includes a manual override.

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 3V1M5B8F Is Used
Grippers on a bench-top pick-and-place
Several small spring-return grippers on a bench-top handling unit each get their own station, so a part is released the instant its coil de-energises.
Wire-strip clamp bank
In an eight-lane wire-processing machine, single-acting clamps hold insulated conductors steady while blades strip each end, one DC24V station per lane.
Label-pad hold-down on a palletiser
A print-and-apply head uses a short-stroke spring-return ram to press each label onto cartons on the palletiser, vented between cycles by its 3/2 station.
Is the Airtac 3V1 Solenoid Valve 3V1M5B8F the Right Part?
3V1 is the entry body of the 3V family and has no published Cv, so confirm flow-critical sizing with us first. When you outgrow M5, 3V2 steps up to 1/8in and 1/4in ports with an NC/NO choice, Cv 0.18-0.19 and a vacuum rating, while 3V3 reaches Cv 0.62 on 1/4in. Where manifold density beats flow, compare 3V2M. Double-acting cylinders belong on the 5-port AirTAC 4V series, not here.
Confirm five things: the M5 port against your fittings (no thread variant exists at this size), the DC24V coil, the DIN plug entry, eight stations per shared base, and the hardware you need - 3V1-P30 connecting-screw bases, 3V1-P31 O-rings and long screws or 3V1-P32 brackets.
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 Blank any unused station on the base before pressurising.
- check Wiring by qualified personnel, per AirTAC documentation.
Airtac 3V1 Solenoid Valve 3V1M5B8F FAQ
Operating pressure 0-0.8 MPa (0-114 psi), temperature -20 to 70 C, IP65 (DIN 40050) coils. Family coil power: AC220V 4.5 VA, AC110V 4.5 VA, AC24V 5.0 VA, DC24V 3.0 W, DC12V 2.5 W; this eight-station assembly uses the 3.0 W DC24V coil per position. No Cv or effective-area figure is published for 3V1.
The 3V1 ordering code carries no NC/NO position, so the valve is not NC/NO selectable. AirTAC's catalogue describes the 3V1 as a direct-acting normally open type, and every unit is supplied in a single fixed initial state - confirm it on the datasheet before wiring your circuit. For an NC/NO choice, step up to the 3V2 series.
