    Description

    The hydraulic control butterfly valve is the most advanced pipeline control equipment at home and abroad, mainly installed in the hydro power station turbine outlet, used as a turbine inlet valve; or installed in water conservancy, electricity, water supply and drainage and other pump station pump outlet.

    The valve and the pipeline work with the host, in accordance with the principle of hydraulic transition process, through the default opening and closing procedures and the effective elimination of pipeline water hammer, to achieve reliable pipeline cut off and play a protective pipeline system security role.
