About the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V41015B
The B03-4V41015B is AirTAC's explosion-proof build of the 4V410-15B, engineered for hazardous and flammable atmospheres where standard valves are not acceptable. This 5/2-way single solenoid valve directs compressed air to double-acting cylinders and actuators, using a spring return that resets the spool the moment the DC24V signal is removed. It delivers a substantial 48 mm² effective area (Cv 2.82) - the largest flow class in the 4V400 family - making it a strong match for cylinders in the 80-125 mm range.
The B03- prefix signals the explosion-proof enclosure and coil construction, but the exact protection level, certification body, and gas/dust group are not specified in our data. You must confirm those details with us before installation in a classified area. This unit weighs 590 g, responds in 0.05 s or less, and runs on a 3.0 W DC24V coil with a standard terminal box for secure wiring.

Flow & Coil Options
| Effective area | See datasheet |
|---|---|
| Flow coefficient | Cv — |
| Response time | ≤ 0.05 s |
| Coil power | AC 3.5–4.5 VA · DC 2.5–3.0 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 B03-4V Explosion-Proof Solenoid Valve B03-4V41015B Is Used
Hazardous Process Lines
Controls double-acting actuation on chemical or petrochemical process lines where flammable vapors may be present. The explosion-proof build addresses ignition risk, though the exact zone rating must be confirmed with us.
Large-Bore Clamping
Drives heavy clamping cylinders on machining fixtures with the 48 mm² flow capacity needed for fast, positive engagement. Spring return retracts the clamp automatically when the DC24V signal drops.
Material Handling Lifts
Operates double-acting lift cylinders on palletizers or conveyors in dusty environments. The explosion-proof enclosure suits areas with combustible dust, subject to confirming the specific rating with us.
Is the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V41015B the Right Valve?
Choose the B03-4V41015B when your application demands explosion-proof construction AND the high flow of the 4V400 body. If your cylinder is smaller than 80 mm, the 4V300 series (Cv 1.65) may be more economical, but for large-bore actuators this 1/2" port valve is the right class. The single solenoid spring-return design is ideal for fail-safe retraction when power is lost - a key safety feature in many process applications.
When replacing an existing valve, verify five points: body size (4V400), function (5/2 single), port and thread (1/2" PT), coil voltage (DC24V), and electrical entry (terminal box). The B03- prefix adds the explosion-proof requirement, so also confirm that the protection rating matches your zone classification - contact us with your specific hazardous-area details before ordering.
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 B03-4V Explosion-Proof Solenoid Valve B03-4V41015B FAQ
B03- marks AirTAC's explosion-proof build of the standard 4V410-15B. It is intended for hazardous or flammable atmospheres where a standard valve could ignite the surroundings. Our data does not include the specific protection level, certification number, or gas/dust group - you must confirm those details with us for your particular zone before installation.
This 5/2-way valve has a 48 mm² effective area (Cv 2.82), which suits double-acting cylinders in the 80-125 mm range. It is a spring-return single solenoid, so it needs a constant DC24V signal to stay energized; removing power springs the spool back to its home position. The response time is 0.05 s or less.
