About the Airtac 4V100 Solenoid Valve 4V110M5B-W
The 4V110M5B-W pairs the 5/2 spring-return spool of the 4V100 family with M5 ports and a low-draw DC24V solenoid, wired through a terminal box. Because the coil needs only 2.8 W, a small PLC relay output or a 24 V battery rail can switch it without a dedicated driver stage. Pressurise the coil and the cylinder extends; remove it and the spring returns the spool, retracting the double-acting actuator every time.
The flow class stays at 10.2 mm2 effective area (Cv 0.6), which suits double-acting cylinders of about O16-32 mm bore. Switching completes in 0.05 s or less, the valve carries IP65 (DIN40050) protection with class B insulation, weighs 120 g, and runs on 0.15-0.8 MPa of filtered air without lubrication.

Flow & Coil Options
| Effective area | 10.2 mm² |
|---|---|
| Flow coefficient | Cv 0.6 |
| Response time | ≤ 0.05 s |
| Coil power | AC 3.5 VA · DC24V 2.8 W · DC12V 2.5 W |
| Protection / insulation | IP65 (DIN40050), B-class |
| Voltage options | DC24V, DC12V, AC110V, AC220V |
| Manual override | Yes (locking / non-locking) |
Size the valve so effective area / Cv is not the bottleneck for your cylinder bore and speed. Undersized valves slow the actuator. Note 5/3 (center) versions have a smaller effective area than the 5/2 of the same body size.

Where the Airtac 4V100 Solenoid Valve 4V110M5B-W Is Used
Relay-driven indexer on a tabletop labeller
The 2.8 W DC24V coil switches directly from a spare PLC relay output, advancing a small double-acting pusher cylinder through label-application indexing strokes at up to 5 cycles per second.
Reject pusher on a benchtop checkweigher
A compact O20-25 mm push cylinder nudges off-weight packs off the belt. Cv 0.6 matches this bore class, and the spring return clears the lane automatically whenever control power fails.
Portable field test kit actuation
Running from a 24 V battery, the low-power coil suits mobile diagnostic rigs; IP65 sealing and the 0.05 s response keep small double-acting test actuators crisp and dust-safe outdoors.
Is the Airtac 4V100 Solenoid Valve 4V110M5B-W the Right Valve?
Electrical choice comes first on this SKU: you have the terminal-box entry (no I in the code); if your panel would rather take a pre-wired 0.5 m flying lead, order the grommet version by adding I instead. Voltage codes run A, B, C, E, F - this one is B, DC24V. On flow, 4V100 offers nothing smaller than M5, so you sit at the bottom of the range; the same Cv 0.6 orifice is available on the 4V110-06 with 1/8 in ports, and the 4V200 body (Cv 1.0) is the step up for larger bores or quicker cycles. Mount one valve on a 4V100 base now and expand into a manifold group later.
For a drop-in replacement, verify all five: 4V100 body, function 10 (single solenoid with spring return), M5 port with no thread letter, voltage B = DC24V, and blank entry code for the terminal box.
Quick checklist
- ✓ Required flow (Cv) for cylinder & speed
- ✓ Function: single / double / 5-3 center
- ✓ Coil voltage (DC24 / AC220 …)
- ✓ Port thread (M5 / 1/8 / 1/4 / 3/8 / 1/2)
- ✓ Single valve or manifold base?
Installation & Wiring Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 0.8 MPa operating pressure.
- check Match coil voltage to your controller output.
- check Use the manual override to test before powering.
- check Fit silencers or fittings to the exhaust ports.
- check Wiring by qualified personnel per AirTAC docs.
Airtac 4V100 Solenoid Valve 4V110M5B-W FAQ
This SKU uses terminal-box entry: land the two coil leads inside the box and seal it to keep the IP65 (DIN40050) rating intact. The coil draws 2.8 W at DC24V with class B insulation, so an ordinary 24 V relay or transistor output handles it. If you would prefer a factory lead, add I to the code for the grommet version with a 0.5 m pre-wired flying lead. Manual override on the coil end lets you jog the valve during commissioning.
Yes, provided the five code points match: 4V100 body, function 10 (5/2 spring-return, double-acting service), M5 port (no thread letter exists at M5), voltage B = DC24V at 2.8 W, and blank entry code for the terminal box. Performance you can expect: 10.2 mm2 effective area (Cv 0.6), switching in 0.05 s or below, up to 5 cycles/s, 0.15-0.8 MPa working pressure against a 1.2 MPa proof rating, 120 g valve weight, and no lubrication needed on 40 um-filtered air.
