2. Classification
Mine ventilation butterfly valves are expertly categorized based on the control type into two primary types: electric ventilation butterfly valves and pneumatic ventilation butterfly valves.
1) Mine electric ventilation butterfly valves are further classified 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 for automated gas pipeline control.
* The integrated electric ventilation butterfly valve features an inbuilt control system, offering flexible operation directly from the valve body or via remote control, thereby enabling effortless remote switching or adjustment without necessitating an additional control box.
* It supports Modbus, Profibus, and other bus communications, featuring a 485 bus interface for robust data communication.
