Bell Valve
Available for our 3 turbine ranges
Control of turbine opening and closing
Local or remote electrical control
Low-flow operation
Operating
The position of the bell affects the flow absorbed by the turbine :
- When the valve is open, the turbine operates at its nominal flow rate
- When the flow decreases in the river, the gate must be lowered to absorb a lesser flow, so as not to lower the water level upstream.
- When the valve is closed, the turbine is completely stopped and no more water passes through the blades.
Control
The stainless steel bell is set in motion by a hydraulic cylinder. The hydraulic assembly is completed by the pump of your choice:
- A manual pump
- A manually-operated electric pump
The descent speed is constant and controlled by a flow regulator.
