2. Classification
Mine ventilation butterfly valves are expertly crafted and categorized into two types based on their control mechanisms: electric ventilation butterfly valves and pneumatic ventilation butterfly valves.
1) The mine electric ventilation butterfly valves are further classified into split type and integrated type:
* The split electric ventilation butterfly valve, when paired with the innovative KXBC mine explosion-proof valve electric device control box, can seamlessly integrate with the DCS system, facilitating automated control of gas pipelines.
* The integrated electric ventilation butterfly valve features an autonomous control system, allowing for effortless manual operation directly on the valve or remote control for seamless switching and adjustment without requiring an additional control box.
* Equipped with advanced bus communications such as Modbus and Profibus, and a 485 bus interface, this valve ensures robust data communication and integration.
