2. Classification
Mine ventilation butterfly valves are categorized into electric ventilation butterfly valves and pneumatic ventilation butterfly valves based on control types.
1) Electric ventilation butterfly valves for mines are available as either split type or integrated type:
* The split electric ventilation butterfly valve, when paired with the KXBC mine explosion-proof valve electric device control box, can integrate with the DCS system to achieve comprehensive automatic control over gas pipelines:
* The integrated electric ventilation butterfly valve is equipped with its own advanced control system, allowing for both manual operation on the unit itself or remote control capabilities, facilitating effortless remote switching and adjustment without the necessity of a separate control box.
* It supports Modbus, Profibus, and other bus communication options, featuring a 485 bus interface to enable seamless data communication.
* Key performance metrics and parameters of electric ventilation butterfly valves.
