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...
Micro Resistance Slow Closing Check Valve
The Micro Resistance Slow Closing Check Valve is a large-diameter, high-performance non-return valve designed to prevent reverse flow and mitigate water hammer in high-flow systems such as water supply networks, power plants, and industrial pipelines. Featuring a butterfly disc design and an external hydraulic cylinder, this valve ensures smooth, controlled closure to eliminate pressure surges and protect critical infrastructure. Constructed from ductile iron, carbon steel, or stainless steel, this valve is built to handle large volumes of water, oil, or gas with minimal pressure drop. Its hydraulic slow-closing mechanism (adjustable from 5 to 60 seconds) provides precise control over closure...
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.
Mute Axial Flow Check Valve
The Mute Axial Flow Check Valve is a specialized valve designed to provide superior flow control and minimize the risk of water hammer, noise, and vibration in fluid systems. Unlike conventional check valves, the mute axial flow check valve incorporates a streamlined valve disc design and advanced internal structure to ensure smooth operation while significantly reducing the potential for water hammer, which is a common issue in many industrial piping systems. This valve is particularly suitable for applications where noise reduction and protection against system surges are essential.
