About the Airtac 4V100 Solenoid Valve 4V110M5B
The AirTAC 4V110-M5B is a compact 5/2-way single-solenoid directional control valve built on the 4V100 body, designed to direct compressed air to small double-acting cylinders and actuators. Its M5 threaded ports make it a natural fit for benchtop automation and miniature pneumatic systems. This DC24V model operates with a 2.8 W coil and features a spring-return mechanism: the spool shifts when the solenoid is energized and automatically returns to its home position when the signal is removed, making it ideal for applications where a fail-safe default state is required.
With an effective area of 10.2 mm² (Cv 0.6) and a response time of 0.05 seconds or less, the 4V110-M5B suits cylinders roughly in the Ø16-32 mm range. The aluminum-alloy body weighs just 120 g and requires no lubrication, while the IP65-rated enclosure and B-class insulation ensure reliable service in demanding industrial environments.

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 Is Used
Miniature Part Ejection
Controls a small double-acting cylinder to eject components from an assembly nest. The spring-return function ensures the ejector retracts safely when the cycle stops.
Benchtop Fluidic Switching
Directs air in a laboratory automation setup, actuating a small syringe or valve. The M5 ports and 2.8 W DC coil integrate easily with low-power control systems.
Compact Clamping Fixture
Operates a miniature pneumatic clamp on a desktop CNC or 3D-printing jig. The 0.05 s response provides quick, repeatable clamping with a simple on/off signal.
Is the Airtac 4V100 Solenoid Valve 4V110M5B the Right Valve?
Choose the 4V110-M5B when your circuit needs a single, electrically actuated 5/2 valve with a defined spring-return position—power loss immediately resets the spool. The M5 port size is perfect for miniature cylinders and grippers; if your application demands higher flow for larger cylinders or faster cycle rates, consider stepping up to the 4V200 series (Cv 1.0) with 1/4" ports.
For replacement, match all five key points: the 4V100 body size, the 5/2 single-solenoid function (10), the M5 port thread, the DC24V coil voltage, and the standard terminal-box electrical entry. This valve can also be mounted on an integrated manifold base if you are building a multi-valve station for a compact machine.
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 FAQ
With a 10.2 mm² effective area (Cv 0.6), this valve is typically paired with double-acting cylinders in the Ø16-32 mm range. Actual speed depends on the cylinder bore, stroke, and operating pressure, but it is optimized for small-bore actuators common in benchtop and pick-and-place systems.
No. The 4V110-M5B is a single-solenoid, spring-return valve. It requires a constant DC24V signal to hold the shifted position. When power is removed, the internal spring immediately returns the spool to its default state, exhausting the previously pressurized cylinder port.
