B03 Series Explosion-proof Solenoid Valve
Class II Explosion-proof T5 Group | High Safety Encapsulation
Product Features
- Design Evolution: Engineered by taking our highly reliable standard solenoid valves (3V1, 3V, 4V, 4M series) and upgrading them with a specialized explosion-proof coil module.
- Secure Encapsulation: The explosion-proof coil utilizes an advanced potting encapsulation method combined with a hermetic sealing introduction device, ensuring total isolation from flammable external environments.
- Explosion-proof Rating: Strictly complies with Class II Explosion-proof T5 group standards. The maximum surface temperature of the coil is limited to 100°C, making it safe for volatile industrial factory use.
- Built-in Safety Protection: Equipped with a built-in thermal fuse inside the coil structure. In the event of an external electrical fault causing overheating, the fuse will instantly cut off the circuit to prevent ignition.
Valve Body & Structure Correspondence
The mechanical valve body of the B03 series is dimensionally and functionally identical to standard AirTAC directional valves. Please refer to the corresponding standard catalog for detailed flow rates, Cv values, and mechanical operating pressures.
| Explosion-proof Model | Standard Series Equivalent | Valve Function & Type |
|---|---|---|
| B03-3V1 | 3V1 Series | 3/2 Way Direct Acting |
| B03-3V | 3V Series | 3/2 Way Internally Piloted |
| B03-4V | 4V Series | 5/2 Way, 5/3 Way Internally Piloted |
| B03-4M | 4M Series | 5/2 Way Namur Standard Valve |
Note: The primary physical difference between the B03 series and standard series lies in the Coil Assembly and the overall height dimensions due to the explosion-proof housing.
