Hydraulically Controlled Slow Closing Check Valve

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

微阻缓闭止回阀是一种专为泵出口应用设计的节能型止回阀，具备缓闭功能。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，阀瓣开启至大角度，阻力极小；当泵停止或发生逆流时，阀瓣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，保护泵和管道系统。.

Large diameter check valve

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.

静音轴流式止回阀

静音轴流式止回阀是一种专用阀门，旨在提供优越的流量控制，并最大限度地降低流体系统中的水锤、噪音和振动风险。与传统止回阀不同，静音轴流式止回阀采用流线型阀瓣设计和先进内部结构，确保运行平稳，同时显著减少水锤现象（这是许多工业管道系统中的常见问题）。该阀门特别适用于对降噪和系统浪涌保护至关重要的应用场景。.
