Purpose
The hydraulically controlled slow-closing butterfly valve adopts an integrated form of mechanical, hydraulic, electric control, and computer systems. It can replace gate valves, check valves, and regulating valves, saving materials, energy, consumption, and space. This valve features staged opening and closing functions, allowing it to effectively control water hammer during the opening process and effectively eliminate water hammer impact during the closing process, thereby protecting pipelines and equipment safety. However, traditional valves only serve a single function: gate valves only act as gate valves, and check valves only act as check valves. They cannot effectively control water hammer during the opening and closing processes in pipelines. Therefore, hydraulically controlled slow-closing butterfly valves are widely adopted in power plants and water treatment plants.
