It combines the functions of a check valve and a gate valve, offering reliable sealing, low flow resistance, and intelligent...

The Micro Resistance Slow Closing Check Valve is an energy‑saving check valve specifically designed for pump discharge applications, featuring a slow‑closing function. It combines the low flow resistance characteristics of a swing check valve with a hydraulic damping device. During forward flow, the disc opens to a large angle with minimal resistance; when the pump stops or backflow occurs, the disc first closes rapidly for most of its travel, then closes slowly for the remaining travel, thereby greatly reducing water hammer pressure peaks and protecting the pump and pipeline system.

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.
