Main Features and Uses The QMB mine is designed and manufactured specifically for the use conditions of coal mines. It is suitable for the control of valves such as ball valves and disc valves. After matching with high-voltage small-caliber special valves, automatic control is used for coal mine fire, dust drop, and underground central pump room jet pump and vacuum pump. The QMB valve electric device is small in size and light in weight and can be directly connected to the DCS system to achieve automatic control. |
