About the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V22006B
The B03-4V22006B is AirTAC's explosion-proof build of the 4V220-06B, a double-solenoid 5/2-way valve with a memory function. It directs compressed air to double-acting cylinders and actuators, holding its last pulsed position without power. This version is engineered for use in hazardous or flammable atmospheres, making it a critical component for facilities that require specialized equipment.
This valve delivers a 17 mm² effective area (Cv 1.0) and suits cylinders in the ~32-50 mm range. With a DC24V coil drawing just 3.0 W and a response time of 0.05 s or less, it offers efficient and rapid actuation. The B03- prefix indicates the explosion-proof construction, but please confirm the exact protection rating and certification for your specific 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 |

Where the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V22006B Is Used
Hazardous-Area Automation
Controls double-acting cylinders in paint booths, chemical dosing lines, or solvent-handling stations where flammable vapors may be present. The explosion-proof build is designed for such environments.
Memory-Hold Positioning
Ideal for a transfer or indexing fixture that must stay in its last position after a control signal is lost or power is removed. The spool holds its position without holding current, ready for the next pulse.
Assembly Station Actuation
Drives clamping or pressing cylinders in a semi-automated assembly station. The 17 mm² effective area provides reliable speed for 32-50 mm actuators, and the memory function simplifies sequential control.
Is the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V22006B the Right Valve?
Choose the B03-4V22006B when you need a double-solenoid 5/2 valve with memory in an explosion-proof package for a 1/8" port system. Its 17 mm² effective area (Cv 1.0) is well-matched to double-acting cylinders in the 32-50 mm range. If your cylinder is smaller, the 4V100 series (Cv 0.6) may be more economical; for larger bores or faster cycles, step up to the 4V300 (Cv 1.65).
When replacing an existing valve, verify the body size (4V200), function (5/2 double), port and thread (1/8" PT), coil voltage (DC24V), and electrical entry (terminal). The B03- prefix is specifically for explosion-proof applications, so ensure this matches your area classification. For manifold integration, this valve can be mounted on a common base to reduce piping and installation time.
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 B03-4V22006B FAQ
The B03- prefix marks this as AirTAC's explosion-proof version of the standard 4V220-06B. It is built for use in hazardous or flammable atmospheres. The performance specs (17 mm² effective area, Cv 1.0, DC24V coil) are identical to the base model. However, you must confirm the exact protection rating and certification for your specific zone with us before installation.
When you pulse one solenoid, the spool shifts and stays there even after the signal is removed. It holds its position due to land friction and balanced pressure, with no spring and no holding current. It is not magnetically latched. A pulse to the opposite solenoid shifts it back, making it ideal for applications that must retain their last state on power loss.
