This kind of hydraulic control butterfly valve is the ideal equipment for hydropower station pipeline system, suitable for installation in front of the turbine pressure pipe, as the water turbine inlet valve, its role:
1.Safety device for the guide vane can not be closed, turbine accident, emergency shut off , to prevent pipeline system.
2.On the condition of the unit shut down standby, close the valve, cut off the water flow, to prevent long-term leakage of water guide vanes, both to reduce water loss, but also to prevent generating cavitations on the gap of vane end and facade.
3.For maintenance, close the valve and cut off the water. The butterfly valve is also suitable for high-level layout at the beginning of the pressure steel pipe, used as a pressure pipe protection valve, in the case of pressure pipe burst and so on the emergency closure of the cut off the water to prevent accidents to ensure safety.
