About the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V230E06B
The B03-4V230E06B is AirTAC's explosion-proof build of the 4V230E-06B, a 5/3-way double solenoid valve with an exhaust center. When both coils are de-energized, ports A and B vent to exhaust, letting a double-acting cylinder float freely. This makes it ideal for applications where you need to manually position a load or release pressure without moving the actuator. The B03- prefix signals a ruggedized enclosure intended for hazardous or flammable atmospheres-confirm the exact protection rating and certification for your specific zone with us before installation.
This valve delivers an effective area of 13.6 mm² (Cv 0.8) and suits double-acting cylinders in the 32-50 mm range. With a response time of 0.05 s or less, it handles rapid cycling up to 3 cycles per second. The DC24V coil draws just 3.0 W, keeping heat low in sensitive environments. The aluminum-alloy body weighs 360 g and carries IP65 protection, so it shrugs off dust and water spray in demanding industrial settings.

|---|---|
| Flow coefficient | Cv — |
| Response time | ≤ 0.05 s |
| Coil power | AC 3.5–4.5 VA · DC 2.5–3.0 W |

Where the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V230E06B Is Used
Manual Override Stations
In maintenance bays or setup areas, the exhaust center lets operators manually position a double-acting cylinder by hand when the valve is centered. This simplifies tool changes and machine calibration without fighting against trapped air pressure.
Flammable Atmosphere Zones
The B03- explosion-proof build suits facilities handling solvents, fuels, or fine dusts where standard valves could pose an ignition risk. Confirm the exact protection rating and certification with us for your specific zone classification.
Float Positioning Systems
In packaging or assembly lines, the exhaust center allows a cylinder to float freely when not actuated. This helps align components or release tension on a conveyor without complex mechanical disengagement.
Is the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V230E06B the Right Valve?
Choose the B03-4V230E06B when you need explosion-proof construction combined with 5/3 exhaust-center functionality. The exhaust center is the right pick for tool changers, manual override stations, or any process where the cylinder must be free to move when the valve is centered. If your cylinder bore is under 32 mm, step down to the 4V100 series (Cv 0.6) for a more compact, cost-effective package. For bores above 50 mm or faster cycle times, move up to the 4V300 series (Cv 1.65).
When replacing an existing valve, verify the five-point match: body size (4V200), function (5/3 exhaust center), port and thread (1/8" PT), coil voltage (DC24V), and electrical entry (terminal box). The B03- prefix means this is the explosion-proof variant-confirm the protection level and certifications with us to ensure it meets your site's requirements.
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 B03-4V230E06B FAQ
The B03- prefix marks AirTAC's explosion-proof version of the base model 4V230E-06B. It is built for hazardous or flammable atmospheres. We do not list the specific protection level or certification in our data-please confirm the exact rating and certificate for your zone with us before ordering.
When both coils are off, both cylinder ports (A and B) connect to exhaust. This means the cylinder can move freely-no air is trapped on either side. When you pulse one coil, the spool shifts and pressurizes one port while exhausting the other, moving the cylinder in that direction. It is not a load-holding valve; use a mechanical brake or pilot-operated check valve for suspended loads.
