Main features and applications
The ZB series mining explosion-proof valve electric device is specially designed and manufactured for the use conditions in coal mines. Valves suitable for linear motion of valve plates, such as gate valves, distribution valves, and water gates; After adding a two-stage reduction gearbox, it can also be used for valves with a 90 degree rotation of the valve plate, such as butterfly valves, dampers, etc. After being matched with the KXBC mining explosion-proof valve electric device control box, it can be connected with the DCS system to achieve automation control.
