The AirTAC Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V230P06A is a genuine 5/2-way solenoid valve solenoid valve with 230P06A ports and an effective area of See datasheet (Cv —). It is an internally piloted spool valve that directs compressed air to double-acting cylinders and actuators.
The B03-4V230P06A is AirTAC's explosion-proof build of the 4V230P-06A, engineered for hazardous or flammable atmospheres where a standard solenoid valve could pose a risk. As a 5/3-way pressure-center valve, it pressurizes both cylinder ports A and B when de-energized, holding a double-acting actuator in a balanced, pressurized state at the center position. This configuration suits applications requiring a firm, pressure-locked hold rather than a floating or blocked-center condition.
With an effective area of 13.6 mm² (Cv 0.8), this valve delivers reliable mid-range flow for cylinders in the 32-50 mm bore class. The AC220V coil draws just 4.5 VA, and the complete unit weighs 360 g. Response time is 0.05 s or less, and the IP65-rated enclosure protects against dust and water jets. The leading "B03-" prefix identifies this as the explosion-proof variant of 4V230P-06A; please confirm the exact protection rating and certification for your specific zone with us before ordering.

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.

Operate double-acting cylinders in chemical plants or paint shops where flammable vapors may be present. The explosion-proof B03- build provides the necessary protection layer for these sensitive environments.
Hold a work fixture or clamp in a fixed position using the pressure-center function. Both cylinder ports stay pressurized at center, keeping the actuator locked against movement until the next command.
Maintain balanced pressure on both sides of a double-acting cylinder for applications like tensioning or intermediate positioning. The 5/3 pressure-center design prevents drift when the valve is in its neutral state.
Choose the B03-4V230P06A when your application demands explosion-proof construction combined with 5/3 pressure-center functionality. The 1/8" PT ports suit compact pneumatic circuits, while the Cv 0.8 flow handles standard double-acting cylinders up to 50 mm. For smaller bores requiring less flow, step down to the 4V100 series (Cv 0.6); for larger cylinders or faster cycling, step up to the 4V300 series (Cv 1.65).
When replacing an existing valve, verify the five-point match: body size (4V200), function (5/3 pressure center), port size and thread (1/8" PT), coil voltage (AC220V), and electrical entry (terminal box). The B03- prefix specifically indicates the explosion-proof housing, so confirm your hazardous-area requirements with us to ensure the protection level matches your installation environment.
Quick checklist
The B03- prefix identifies this as AirTAC's explosion-proof version of the standard 4V230P-06A. It is built for use in hazardous or flammable atmospheres where standard solenoid valves could be unsafe. The exact protection level, certification, and zone suitability must be confirmed with us for your specific installation.
When both solenoids are de-energized, the valve shifts to its center position where both cylinder ports A and B are connected to the pressure supply. This pressurizes both sides of a double-acting cylinder equally, holding the piston in place. The effective area is 13.6 mm² (Cv 0.8), suitable for 32-50 mm cylinders.
