Large-diameter hydraulic butterfly valve is core control devices in high-flow and long-distance pipeline systems. Their diameter range is typically from DN300 to DN3000. They are driven by hydraulic pressure and integrate functions such as on-off, regulation, check, and water hammer protection. They are widely used in multiple key fields including water conservancy, municipal services, energy, and chemical engineering. The core advantage of this valve lies in its adaptability to high-pressure and high-flow working conditions. It can effectively address the industry pain points such as the difficulty in opening and closing traditional large-diameter valves and the large pressure fluctuations in the system. It is an indispensable key equipment in modern fluid transportation systems.

Its most prominent features are strong driving force, controllable opening and closing, and high safety redundancy. The hydraulic system can output an extremely large torque, meeting the opening and closing requirements of large-diameter and high-pressure working conditions. The opening and closing speed can be adjusted steplessly within 3 to 60 seconds. It supports two-stage closing of fast and slow, which can significantly reduce the water hammer effect and protect the safety of water pumps, pipelines and related equipment.

This customized hydraulic butterfly valve also features a compact structure, energy conservation, high efficiency and flexible control. Its flow path is unobstructed, with a small flow resistance coefficient and low operating energy consumption. It can directly replace the traditional combination of gate valves and check valves, reducing installation space and engineering costs. The control mode is flexible, supporting on-site manual and electric operation as well as remote centralized control by PLC and DCS. It can achieve automated operation and meet the requirements of unmanned stations.

In practical applications, it is often used at the intake of hydropower stations and the outlet of pumping stations in water conservancy and hydropower projects, serving to cut off, check and protect against water hammer. In the field of municipal water supply and drainage, it is often used in pump rooms of water plants and main urban pipe networks to achieve flow regulation and emergency shut-off in case of pipe burst. It is applied in the energy, chemical and metallurgical industries to circulating water systems, cooling systems and oil product transportation pipelines, ensuring continuous production and safe shut-off. In fire protection and long-distance water transmission pipelines, it can quickly respond to instructions, achieve remote control and rapid shut-off in accident conditions, and is fully adapted to various large-scale fluid transportation scenarios.
