About the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V230E06A
The B03-4V230E06A is the explosion-proof build of AirTAC's 4V230E-06A, a 5/3-way double solenoid valve with an exhaust center. It directs compressed air to double-acting cylinders and actuators, and when both coils are de-energized, ports A and B vent to exhaust, allowing the actuator to float freely. This makes it ideal for applications where manual repositioning or emergency release is needed. The B03- prefix indicates a hazardous-atmosphere-rated construction, though the exact protection level and certification must be confirmed with us for your specific zone.
This valve carries a 13.6 mm² effective area (Cv 0.8) and suits cylinders in the ~32-50 mm bore range. Its AC220V coil draws just 4.5 VA, keeping control power modest. The spool responds in 0.05 seconds or less, and the aluminum-alloy body weighs 360 g. With IP65 protection and no lubrication required, it is ready for demanding industrial environments where safety and reliability are non-negotiable.

Specifications follow the official AirTAC 4V series datasheet. Lubrication not required. Confirm coil voltage and thread (PT / NPT / G) against the product label before 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 B03-4V230E06A Is Used
Hazardous-Area Cylinder Control
Operate double-acting cylinders in potentially flammable atmospheres where standard valves are not permitted. The B03- build is designed for such environments, but always verify the exact rating with us.
Manual Override Stations
Use the exhaust center function to vent both cylinder ports, letting operators manually position tooling or fixtures during maintenance, setup, or emergency interventions without fighting air pressure.
Mid-Stroke Stopping
Stop a double-acting actuator at an intermediate position by de-energizing both coils. The load can then be moved by hand, which is useful for alignment tasks in assembly or packaging lines.
Is the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V230E06A the Right Valve?
Choose the B03-4V230E06A when you need a 5/3-way exhaust-center valve in a hazardous area and your cylinder bore is between 32 and 50 mm. The exhaust center function is ideal for stopping a cylinder mid-stroke and allowing it to be moved by hand, which is useful during setup or emergency stops. If your cylinder is smaller than 32 mm, the 4V100 series (Cv 0.6) may be more economical; for bores above 50 mm or faster cycling, step up to the 4V300 series (Cv 1.65).
When replacing an existing valve, match these five points exactly: body size (4V200), function (5/3 exhaust center), port and thread (1/8" PT), coil voltage (AC220V), and electrical entry (terminal box). The B03- prefix means this is the explosion-proof version-confirm the specific protection rating and certification with us to ensure compliance for your zone 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 B03-4V230E06A FAQ
B03- marks this as AirTAC's explosion-proof version of the standard 4V230E-06A. It is built 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 and suitability for your zone.
With both solenoids de-energized, the spool returns to the center position, connecting both cylinder ports A and B to the exhaust port. This vents pressure from both sides of the double-acting cylinder, allowing the actuator to float freely and be moved manually.
