Model Needle Type Valve -Synchronized Application with Turbine

It is a safety cum regulating device suitable for projects having Francis & Kaplan units in order to limit pressure rise and speed rise in permissible range. Advantages on Needle type Valve: Fail safe safety device, as mechanical / hydraulic linkages are used for synchronous operation with turbine. Lesser noise and vibrations as water is discharged through large orifice cylinder. Highly effective in energy dissipation/pressure reduction. Highly effective in flow regulation as per the control requirement of turbine transient.
