Product Description

The hydraulic control butterfly valve represents the pinnacle of advanced pipeline control technology both domestically and internationally. It is primarily designed for installation at the turbine outlet in hydroelectric power stations, functioning as a turbine inlet valve. Additionally, it can be installed at the pump outlet in various pump stations, including those in water conservancy, electricity, water supply, and drainage systems. The valve operates in conjunction with the pipeline and the main equipment, adhering to the principles of the hydraulic transition process. By following preset opening and closing procedures and effectively mitigating water hammer in the pipeline, it ensures reliable pipeline cutoff and plays a crucial role in safeguarding the security of the pipeline system.
