蝶式止回阀

The Hydraulically Controlled Slow Closing Check Valve is a high-performance, intelligent valve designed for large-scale water supply, power generation, and industrial systems. Developed by our company based on decades of experience and advanced technologies, this valve integrates mechanical, hydraulic, and electrical systems to provide precise flow control, water hammer prevention, and energy efficiency. Available in two control system types—Standard Hydraulic Accumulator and Locking Hydraulic Accumulator—this valve is widely used in water treatment plants, power stations, steel mills, and chemical plants. It combines the functions of a check valve and a gate valve, offering reliable sealing, low flow resistance, and intelligent...

微阻缓闭止回阀是一种专为水泵出口应用设计的节能型止回阀，具有缓闭功能。它结合了旋启式止回阀的低流阻特性与液压阻尼装置。在正向流动时，阀瓣以最小阻力开启至大角度；当水泵停止或发生逆流时，阀瓣首先快速关闭大部分行程，然后缓慢关闭剩余行程，从而大幅降低水锤压力峰值，保护水泵和管道系统。.

The Large Diameter Check Valve is a high-performance, butterfly-style non-return valve designed for large-scale piping systems requiring reliable flow control and water hammer prevention. Suitable for water supply, wastewater treatment, power generation, and industrial processes, this valve prevents reverse flow and protects pipelines and equipment from damage caused by backflow or pressure surges. Available in sizes ranging from DN300 to DN2600 (12" to 104"), this valve is constructed from durable materials such as ductile iron, carbon steel, or stainless steel, ensuring long-term performance in demanding environments. Its butterfly disc design minimizes pressure drop and provides efficient, low-maintenance operation.
