About the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V32010A
The B03-4V32010A is the explosion-proof build of AirTAC's 4V320-10A, a 5/2-way double solenoid valve with memory. It directs compressed air to double-acting cylinders and actuators, holding its last pulsed position without power. This variant is engineered for hazardous or flammable atmospheres, making it a safer choice for demanding industrial environments.
With a 28 mm² effective area (Cv 1.65) and a 4 cycle/sec max frequency, it suits ~O50-80 mm bore cylinders. The AC220V coil draws 4.5 VA, and the valve weighs 400 g. Response time is 0.05 s or less. The B03- prefix indicates the explosion-proof version; please confirm the exact protection rating and certification for your 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 B03-4V32010A Is Used
Hazardous-Area Automation
Controls double-acting cylinders in chemical plants or paint shops where flammable vapors may be present, leveraging the B03- explosion-proof build.
Machine Tool Clamping
Operates workholding fixtures on CNC machines, holding the clamp position via the memory function even if power is briefly interrupted.
Material Handling Systems
Drives larger-bore cylinders in conveyors and lift gates, providing reliable 5/2 directional control with the 3/8-inch port capacity.
Is the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V32010A the Right Valve?
Choose the B03-4V32010A when you need explosion-proof protection for a double-acting cylinder in a hazardous area. Its Cv 1.65 handles ~O50-80 mm bores; step down to the 4V200 (Cv 1.0) for smaller cylinders or up to the 4V400 (Cv 2.82) for larger ones. The double solenoid memory function suits applications where the valve must retain its position during a power loss.
For replacement, match the 4V300 body size, 5/2 double function, PT3/8 ports, AC220V coil, and terminal box entry. Verify the explosion-proof rating with us to ensure it meets your site's requirements.
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 B03-4V32010A FAQ
The B03- marks this as AirTAC's explosion-proof version of the standard 4V320-10A. It is built for hazardous or flammable atmospheres. You must confirm the exact protection rating and certification for your specific zone with us, as we do not publish those details here.
When pulsed, the spool shifts and stays in that position mechanically, held by friction and balanced pressure-no spring returns it. It requires no holding current, but it is not a safety brake; for suspended loads, add a mechanical brake or pilot-operated check valve.
