Industry-leading precision-engineered valves for global projects.
Bridging the Gap Between Cost-Efficiency and High-Integrity Flow Control.
In the modern industrial landscape, the Custom Double Flanged Butterfly Valve has emerged as the cornerstone of reliable fluid management. Unlike standard wafer or lug type valves, the double flanged design provides superior structural integrity and ease of maintenance for large-diameter pipelines. As a leading manufacturer, we recognize that the demand for "Information Gain" in procurement is higher than ever. Engineering teams are no longer just looking for a component; they are seeking a solution that minimizes "Total Cost of Ownership" (TCO) through material science and precision manufacturing.
The double flanged configuration is particularly critical in applications where the valve must withstand high pressure and significant pipeline stress. By utilizing two sets of bolts for each flange, the valve body remains securely anchored even during downstream maintenance. Our R&D department focuses on "Triple Offset" geometry to ensure zero-leakage performance, reducing friction during operation and significantly extending the service life of the EPDM or Metal seals.
Supply Chain Advantage: Operating from the heart of China's valve manufacturing hub, KR Valve Group leverages a sophisticated ecosystem of raw material sourcing and high-precision CNC machining. This allows us to offer customization at a scale that local Western manufacturers often cannot match, providing significant lead-time advantages for massive infrastructure projects in Europe, Asia, and the Americas.
Our products strictly adhere to international standards including ISO 9001, ANSI, API 609, AWWA C504, and DIN F4/F5. We provide full traceability reports for every batch produced.
We provide localized technical documentation and 24/7 remote engineering support to ensure seamless integration into municipal water systems and chemical plants worldwide.
Streamlined logistics and DDP/CIF shipping options reduce the complexity for global enterprises, ensuring that our valves arrive ready for immediate installation.
KR has more than 20 years of experience in producing standard and non-standard valves of various types. We supply a wide selection of over 500 valve products, including butterfly valve, gate valve, check valve, water control valve, as well as all their matching and accessory products. These products have applications in various industries such as water treatment, dam construction, commercial buildings, energy and heating, chemical engineering, etc.
Today, KR VALVE’s products have been exported to over 50 countries and regions in Europe, Asia, Africa, and Oceania, providing project construction and brand marketing services to thousands of customers.

Industry Expertise
Our technicians continuously design and develop products that meet market requirements, with over 20 series and 500 varieties currently in production.
Manufactured under ISO-9001. We utilize over 30 advanced production units to ensure timely delivery and inventory management.
"Zero Leakage" is our core principle. Every valve undergoes pressure, appearance, and dimension checks before shipping.
Used in main distribution lines in Italy and Brazil for reliable potable water flow.
Corrosion-resistant materials (SS316/Duplex) for high-salinity environments.
Precision control for commercial heating and cooling in high-rise buildings.
Lined valves for handling aggressive media with zero risk of leakage.
The double flanged design allows for dead-end service and easier installation in large-scale pipelines where structural stability is paramount. It provides higher pressure ratings and is more resilient to thermal expansion.
We offer custom body materials (WCB, CF8, CF8M, Ductile Iron), various seat materials (EPDM, NBR, PTFE, Metal), and actuation methods (Manual, Pneumatic, Electric, Hydraulic).
By integrating ISO-9001 management with international certifications and utilizing 100% pressure testing protocols, we guarantee that our products exceed the performance of traditional European and American brands at a more competitive price point.
Depending on the series and customization, standard orders are fulfilled within 4-6 weeks, with monthly inventory updates ensuring rapid response for urgent replacements.
