About the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V230C06A
The B03-4V230C06A is AirTAC's explosion-proof build of the 4V230C-06A, a 5/3-way closed-center solenoid valve in the 4V200 body size. The leading "B03-" prefix designates this as the hazardous-atmosphere version of the base valve, intended for environments where flammable gases or vapors may be present. This model directs compressed air to double-acting cylinders and actuators, and at its center position blocks all ports to hold the cylinder rigidly in place.
With an effective area of 13.6 mm² (Cv 0.8), this valve suits cylinders in the 32-50 mm range and operates at up to 3 cycles per second. The AC220V coil draws 4.5 VA, and the complete valve weighs 360 g. Response time is 0.05 seconds or less. Because this is the explosion-proof variant, please confirm the exact protection rating, certification, and suitability for your specific zone with us before ordering.

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 B03-4V230C06A Is Used
Mid-Stroke Positioning
Use the closed-center function to lock a double-acting cylinder at any point in its stroke for precise fixture positioning in assembly operations, holding the load until the next command.
Hazardous-Area Automation
Deploy in facilities with potentially flammable atmospheres where standard valves are not permitted, such as chemical processing or paint shops, thanks to the explosion-proof B03- build.
Clamping Operations
Energize one solenoid to clamp a workpiece, then de-energize both to hold the clamp pressure via the blocked center, ideal for machining fixtures in explosive environments.
Is the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V230C06A the Right Valve?
Choose the B03-4V230C06A when you need a 5/3 closed-center valve in an explosion-proof configuration for a double-acting cylinder in the 32-50 mm range. The closed-center function holds the cylinder position when both solenoids are de-energized, which is ideal for stopping a load mid-stroke. If your cylinder is smaller than 32 mm, consider the 4V100 series with Cv 0.6; for larger bores or faster cycling, step up to the 4V300 series with Cv 1.65.
For replacement, match the 4V200 body size, the 5/3 closed-center function, the 1/8" PT port thread, the AC220V coil voltage, and the terminal box electrical entry. If you need a different thread type (G or NPT) or a grommet lead, those are separate SKUs. For guaranteed load holding in vertical applications, add a pilot-operated check valve at the cylinder ports-the valve alone should not be relied upon as a safety brake.
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 B03-4V230C06A FAQ
The B03- prefix marks this as AirTAC's explosion-proof version of the base 4V230C-06A valve. It is built for use in hazardous or flammable atmospheres. The exact protection level, certification, and approved zones must be confirmed with us, as we do not publish those details in this listing.
In the center position, both solenoids are off and all ports are blocked. This traps air on both sides of a double-acting cylinder, holding it firmly in place. It is not a safety brake for suspended loads-use a mechanical brake or check valves if load holding is critical.
