About the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V230P06B
The B03-4V230P06B is the explosion-proof build of AirTAC's 4V230P-06B, a 5/3-way pressure-center solenoid valve. It directs compressed air to double-acting cylinders or actuators, and at its center position it applies pressure to both cylinder ports simultaneously. This valve is built for hazardous or flammable atmospheres, but you must confirm the exact protection rating and certification for your specific zone with us before installation.
This 1/8-inch PT-ported valve has an effective area of 13.6 mm² (Cv 0.8) and suits cylinders in the 32-50 mm range. Its DC24V coil draws just 3.0W, and the valve weighs 360g. The response time is 0.05 seconds or less, and the IP65-rated enclosure protects the coil and terminal box from dust and water jets.

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 B03-4V230P06B Is Used
Hazardous-Area Actuation
Controls double-acting cylinders in environments where flammable gases or vapors may be present, such as chemical processing or solvent handling lines. The explosion-proof build isolates the coil from the atmosphere.
Pressure-Hold Positioning
The pressure-center function holds a cylinder mid-stroke by applying equal pressure to both sides. Use it in clamping fixtures where a workpiece must be held firmly without drifting during a pause in the cycle.
Process Plant Automation
Suitable for automated valves and actuators in refineries or paint shops where the control air must be switched reliably despite a potentially explosive ambient. Confirm the zone rating with us before deployment.
Is the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V230P06B the Right Valve?
Choose the B03-4V230P06B when you need a 5/3 pressure-center valve in an explosion-proof enclosure for a double-acting cylinder in a hazardous area. The 1/8-inch port and Cv 0.8 flow suit smaller cylinders; if you need more flow, step up to the 4V300 series with its larger Cv. For a smaller cylinder, the 4V100 series offers a lower Cv 0.6 alternative.
When replacing an existing valve, match the body size (4V200), function (5/3 pressure center), port thread (PT 1/8"), coil voltage (DC24V), and electrical entry (terminal box). The B03- prefix indicates the explosion-proof version, so verify the specific protection level and certification with us for your application.
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 B03-4V230P06B FAQ
The B03- prefix marks AirTAC's explosion-proof build of the standard 4V230P-06B valve. It is intended for use in hazardous or flammable atmospheres. We do not list the specific protection level or certification here-please contact us to confirm the exact rating for your zone.
At the center position, a pressure-center valve (30P) applies supply pressure to both cylinder ports, which can hold a cylinder in place but also pressurizes both sides. A closed-center valve (30C) blocks all ports, trapping air and holding the cylinder with no additional pressure. The pressure-center type is often used when you need to push a load in either direction from a stopped position.
