Main Features and Applications
MD mining explosion-proof electric butterfly valve is used for water pipelines such as coal mine fire protection and environmental purification. There are two types: split type and integrated type:
After being used in conjunction with the KXBC mining explosion-proof valve electric device control box, the split type electric butterfly valve can be connected to the DCS system to achieve
Automated control of gas pipelines;
The integrated electric butterfly valve comes with a control system, which can be switched on and off or remotely on the body, achieving remote switching or adjustment without the need for a separate control box.
Modbus, Profibus and other bus communication can be configured, with 485 bus interface to achieve data communication.
