Main Features and Applications
QBY Partial Rotary Mining Explosion proof Integrated Valve Electric Device (hereinafter referred to as the electric device) is a new generation of intelligent control mechanism for mining valves. It comes with an intelligent control unit and is designed with an electromechanical integration mechanism. It can achieve on-site control, centralized control, and remote control of mining valves without the need for a dedicated control box. Modbus, Profibus and other bus communication can be configured, with 485 bus interface to achieve data communication. This series of electric devices is very convenient for users to install, debug, and maintain, which can greatly save installation costs and shorten installation cycles. It is specially designed and manufactured for the use conditions and intelligent development of coal mines. QBY electric installation is suitable for valves with 90 degree rotation of valve plates, such as butterfly valves, dampers, etc.
