2. Classification
The mine ventilation butterfly valves are expertly categorized based on their control mechanisms into electric ventilation butterfly valves and pneumatic ventilation butterfly valves.
1) The mine electric ventilation butterfly valves are further refined into split type and integrated type:
* The split electric ventilation butterfly valve, when paired with the KXBC mine explosion-proof valve electric device control box, seamlessly integrates with the DCS system, enabling sophisticated automatic control of the gas pipeline:
* The integrated electric ventilation butterfly valve is equipped with its own sophisticated control system, providing the versatility to switch operations on the body itself or opt for remote control, facilitating effortless remote switching or adjustment control without the necessity for a separate control box.
* Equipped for the future, it offers Modbus, Profibus and other advanced bus communications, complete with a 485 bus interface that ensures seamless data communication.
