Hydraulic controlled slow closing butterfly valve is currently one of the more advanced pipeline control equipment both domestically and internationally. It is mainly installed at the inlet of hydroelectric power plants and used as an inlet valve for the turbine; Or installed at the outlet of water pumps in various pumping stations such as water conservancy, electricity, water supply and drainage, to replace check valves and gate valves. When working, the valve cooperates with the pipeline host, and according to the principle of hydraulic transition process, through the effective setting of the electro-hydraulic control program, it achieves reliable shut-off of the pipeline, effectively eliminates pipeline water hammer, and can achieve automatic valve closing without electricity, playing a role in protecting the safety of the pipeline system.
The intelligent heavy hammer hydraulic controlled slow closing butterfly valve produced by our company uses the potential energy of the heavy hammer as the power source for automatic valve closing, adopts a PLC intelligent control system, and can be equipped with manual and automatic locking devices according to user requirements. It has a small flow resistance coefficient, high degree of automation, complete functions, stable and reliable performance. Based on extensive collection, research and summary of the performance of similar products at home and abroad, our company has introduced multiple research results from the valve, hydraulic, electrical and other industries, and developed a new generation of intelligent energy-saving products.
