About the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V230C06B
The B03-4V230C06B is AirTAC's explosion-proof version of the 4V230C-06B, a 5/3-way closed-center solenoid valve built for double-acting cylinders in potentially hazardous atmospheres. The 'B03-' prefix signals this hardened build, while the valve itself directs compressed air with a 13.6 mm² effective area (Cv 0.8) and a 3 cycle/sec max frequency. At center, all ports block, locking the cylinder in place - ideal for intermediate positioning.
This DC24V model draws just 3.0 W, keeping heat low inside the enclosure. The 1/8" PT ports and 360 g aluminum body suit it to compact automation cells. Response time stays at or below 0.05 s. Since the exact protection level and certification depend on your zone, confirm the rating with us before installation - we'll match the build to your hazard classification.

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 B03-4V230C06B Is Used
Intermediate Positioning
Lock a double-acting cylinder at any mid-stroke point by de-energizing both coils. The closed center blocks all ports, holding the load steady for precise assembly or inspection steps.
Hazardous-Area Actuation
Operate clamps or pushers in atmospheres where flammable gases or vapors may be present. The B03- explosion-proof build reduces ignition risk, though you must confirm the exact zone rating with us.
Dual-Coil Safety Stops
Use the two solenoid coils to drive a cylinder to either end position, then cut both signals to hold it there. This works well for press guards or fixture locks needing a positive stop.
Is the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V230C06B the Right Valve?
Choose the B03-4V230C06B when you need explosion-proof construction plus 5/3 closed-center control for a double-acting cylinder in the 32-50 mm range. The 13.6 mm² / Cv 0.8 flow handles moderate speeds; if you need faster cycling, step up to the 4V300 series (Cv 1.65). For smaller bores under 32 mm, the 4V100 (Cv 0.6) may suffice and save space.
When replacing an existing valve, match these five points exactly: 4V200 body size, 5/3 closed-center function, 1/8" PT ports, DC24V coil, and terminal-box electrical entry. The B03- prefix means you're getting the explosion-proof variant - verify the protection rating with us for your specific hazardous area 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 B03-4V230C06B FAQ
B03- marks AirTAC's explosion-proof build of the base 4V230C-06B valve. It's designed for use in hazardous or flammable atmospheres where a standard valve could ignite gases. The exact protection level and certification depend on your installation zone - please confirm the rating with us before purchasing.
With both coils de-energized, the spool returns to center and blocks all four ports (P, A, B, and both exhausts). This traps air on both sides of a double-acting cylinder, locking it in position. To move the cylinder, energize one coil to shift the spool and pressurize one side while exhausting the other.
