- The hydraulic control ball valve is currently a relatively advanced pipeline control equipment both domestically and internationally, mainly installed at the inlet of hydroelectric turbines to replace the functions of check valves and gate valves. During operation, the valve cooperates with the pipeline host. According to the principle of hydraulic transient processes, through preset opening and closing programs, it effectively eliminates pipeline water hammer, achieves reliable shut-off of the pipeline, and plays a role in protecting the safety of the pipeline system.
- The heavy hammer-type hydraulic control ball valve for hydropower has comprehensive electro-hydraulic control functions and can operate as an independent system for local high-level control without additional configuration. At the same time, it can serve as a device unit in a distributed control system (DCS), managed centrally by a computer via I/O channels, enabling coordinated operation with pumps, turbines, bypass valves, and other pipeline equipment. It is also equipped with manual valve opening and closing functions to meet valve debugging and control requirements under special working conditions.
- The heavy hammer-type hydraulic control ball valve for hydropower offers excellent control performance, a wide adjustment range, and strong adaptability. The electro-hydraulic control system features multiple adjustment points, allowing opening and closing programs to be set according to different pipeline control requirements. Under both normal power supply and sudden water interruption conditions, the valve can automatically close in two stages—fast and slow—according to preset time and angle settings. This not only eliminates destructive water hammer but also controls the reverse speed and reverse time of the pump, effectively reducing pressure fluctuations in the pipeline network, preventing runaway accidents in pumps and turbine units, and ensuring the safe and reliable operation of pipeline system equipment.
- The heavy hammer-type hydraulic control ball valve for hydropower can replace the functions of the original gate valve and check valve at the pump outlet (serving dual purposes). The mechanical, electrical, and hydraulic systems are integrated into a single unit, reducing the footprint, volume, and weight. It features a small flow resistance coefficient, low energy consumption, and simple operation.
- The heavy hammer-type hydraulic control ball valve for hydropower can be used for flow regulation.
- The heavy hammer-type hydraulic control ball valve for hydropower has a PTFE-structured sealing surface, ensuring easy opening and closing and reliable sealing.
Applications
The hydraulic control ball valve is currently a relatively advanced pipeline control equipment both domestically and internationally, mainly installed at the inlet of hydroelectric turbines to serve as the inlet valve for turbines, or installed at the outlets of pumps in various pump stations for water conservancy, electricity, water supply, and drainage. The hydraulic control ball valve features a small flow resistance coefficient, a high degree of automation, comprehensive functions, and stable performance.
