Product introduction
Liquid-controlled check eccentric semi-ball valve is mainly installed in the inlet of hydropower station turbine, used as turbine inlet valve; or installed in water conservancy, electric power, water supply and drainage and other types of pump station pump outlet, to replace the check valve and gate valve. When working, the valve cooperates with the pipeline host, according to the principle of hydraulic transition process, through the effective setting of electro-hydraulic control program, realizes the reliable cut-off of pipeline, effectively eliminates the water hammer of pipeline, and realizes the automatic shut-off of the valve without electricity, which plays the role of protecting the safety of pipeline system.
