Brand: Yibiao valve    Product Model: HH

Liquid-controlled check butterfly valve is widely used in high head hydropower stations. When working, the valve cooperates with the hydraulic turbine, and in accordance with the principle of hydraulic transition process, through the preset opening and closing procedures, it effectively eliminates the pipeline water hammer, realizes the reliable cut-off of the pipeline, and plays the role of protecting the safety of pipeline system.

Installed at the water inlet of the turbine's worm shell, it provides reliable and safe working conditions when the unit is shut down for maintenance; reduces the unit's water leakage when the unit is shut down for a long period of time, and quickly fills up the water when it is turned on, so that the unit quickly enters into the working state; it also prevents the event of the unit's flying away. The valve has high degree of intelligence, complete functions, stable and reliable performance, and the flow resistance coefficient is extremely small.
