About the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V230P08A
The B03-4V230P08A is the explosion-proof build of AirTAC's 4V230P-08A, a 5/3-way pressure-center solenoid valve that routes compressed air to double-acting cylinders and actuators. At its center position, both cylinder ports are pressurized simultaneously, which can be used to balance a load or hold a position with equal force on both sides. The B03- prefix marks this as the hazardous-atmosphere version of the base valve, built for use in environments where flammable gases or vapors may be present.
This valve delivers a 13.6 mm² effective area (Cv 0.8) and weighs 360 g, suiting it to double-acting cylinders in the 32-50 mm range. The AC220V coil draws 4.5 VA, and the valve responds in 0.05 s or less. The terminal-box electrical entry simplifies wiring in fixed installations. Because the B03- prefix indicates an explosion-proof construction, confirm the exact protection rating and certification for your specific zone with us before ordering.

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 B03-4V230P08A Is Used
Hazardous-Area Actuation
Controls double-acting cylinders in zones where flammable vapors may be present. The B03- explosion-proof build is suited to chemical processing and solvent-handling stations.
Balanced Pressure Holding
The pressure-center function pressurizes both cylinder ports at rest, which can hold a piston in position with equal force on both sides. Useful for tool changers or positioning fixtures.
Process Valve Control
Operates pneumatic actuators on process valves in plants where explosion-proof equipment is specified. The 0.05 s response time supports consistent cycle rates.
Is the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V230P08A the Right Valve?
Choose the B03-4V230P08A when you need a 5/3 pressure-center valve with explosion-proof construction for a double-acting cylinder in a hazardous area. The 13.6 mm² effective area (Cv 0.8) suits 32-50 mm cylinders; step down to the 4V100 series (Cv 0.6) for smaller bores, or up to the 4V300 series (Cv 1.65) for larger cylinders or faster cycling. The pressure-center function is ideal for applications that require equal pressure on both sides of a piston at rest.
When replacing an existing valve, match the body size (4V200), function (5/3 pressure center), port size and thread (PT 1/4"), coil voltage (AC220V), and electrical entry (terminal box). The B03- prefix confirms this is the explosion-proof variant, but you must verify the specific protection level and certifications for your installation with us.
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 B03-4V230P08A FAQ
B03- marks this as AirTAC's explosion-proof version of the standard 4V230P-08A. The valve is built for use in hazardous or flammable atmospheres. We do not publish the protection level or certification details in this listing - confirm the exact rating and certification for your zone with us before purchasing.
In the center position, both cylinder ports A and B are pressurized simultaneously. This creates equal pressure on both sides of a double-acting cylinder piston, which can hold the piston in place or balance a load. The valve has a 13.6 mm² effective area (Cv 0.8) and suits 32-50 mm cylinders.
