The cylinder controlled quick-closing butterfly valve is driven by a hydraulic cylinder with an eccentric disc structure, featuring rapid cut-off capability that can achieve second-level flow interruption in emergency conditions, effectively preventing medium backflow and leakage. The opening and closing speed as well as the buffer stroke can be flexibly adjusted according to the on-site pipeline anti-shock requirements, adapting to different working scenarios. Equipped with an energy storage device, the valve can automatically link to complete quick closing in case of power failure, pressure loss or system failure, providing safety guarantee for equipment and pipelines.
The control box of hydraulic butterfly valve compatible with DCS/PLC self-control, can be operated locally and remotely, and can be manually/energy stored to close valves in case of power or voltage loss, ensuring safety and reliability.
The eccentric butterfly valve suitable for large caliber, medium and high pressure, and can be used for media such as water, sewage, circulating water, oil, gas, etc.
The flange double offset butterfly valves compact and lightweight structure, small footprint, easy maintenance, debugging, and replacement of accessories in the later stage, reducing operation and maintenance costs.
Standard export wooden case packaging
The adjusted hydraulic eccentric butterfly valves are widely used for high-performance cut-off/regulation of medium and high voltage large-diameter pipelines in water conservancy, power, municipal, chemical and other industries.
