Aug 29 2025Engineering the Giants: JRVAL's R&D Breakthrough in Ultra-Large Diameter (DN3000+) Butterfly Valves
JRVAL, a premier butterfly valve manufacturer with deep roots in foundry technology, has successfully developed and deployed an ultra-large diameter (DN3000) triple eccentric butterfly valve. This case study highlights our integrated capabilities, from expert butterfly valve casting to precision valve machining, delivering a high-performance solution for a critical infrastructure project.
The Challenge: Colossal Scale Meets Extreme Demands
A major municipal water transport project required a large diameter butterfly valve solution exceeding DN3000. The operational demands were immense: controlling massive water flow with zero leakage, ensuring long-term reliability to prevent catastrophic failures, and withstanding significant operational pressures. Standard industrial butterfly valve solutions were not viable due to the sheer scale and the stringent performance criteria. The client, a mid-sized engineering firm, needed a high performance butterfly valve (HPBV) that offered the reliability of a premium brand without the exorbitant cost, a challenge many SMEs face in the butterfly valve oil and gas industry and large-scale waterworks.
The Solution: A Fusion of Foundry Expertise and Precision Engineering
As a source butterfly valve factory, JRVAL was uniquely positioned to tackle this challenge. Our solution was not just a product, but a vertically integrated engineering process, leveraging our core strengths.
Superior Design: The Triple Offset Advantage
For this application, our triple offset butterfly valve (also known as a tri eccentric butterfly valve) was the only logical choice. Unlike a double eccentric butterfly valve, the triple eccentric geometry completely eliminates friction between the seal and seat throughout its cycle. This sophisticated eccentric butterfly valve design ensures a durable, bi-directional, zero-leakage metal to metal butterfly valve seal, which is critical for a high pressure butterfly valve of this magnitude. This design is the pinnacle of high quality butterfly technology.
Mastery in Materials and Casting
Our 20-year heritage in casting, led by our founder, a casting expert, was the cornerstone of this project's success. A flawless butterfly valve casting is non-negotiable for a DN3000 wcb butterfly valve body. We ensured the carbon steel butterfly valve material met all stringent client standards, including ASME valve and DIN valve requirements. The integrity of the cast, free from porosity or imperfections, guarantees the structural strength needed to handle immense operational stresses. This foundational expertise sets us apart from other manufacturers of butterfly valves.
Specialized Machining and Assembly
Our key advantage lies in providing specialized dimensions ("专标专供"). Using large-scale CNC butterfly valve machining centers, we achieved micrometer precision on the critical sealing surfaces of the seat ring for butterfly valves and the disc. This precision butterfly valve disc machining is essential for the laminated seal of the triple offset valve to function correctly. The final butterfly valve assembly was a massive double flanged butterfly valve, with a butterfly valve with worm gear for reliable manual operation, conforming strictly to API 609 butterfly valve and ISO 5752 butterfly valve dimensions for seamless integration.
Results: Unprecedented Reliability and Value
The DN3000 triple offset butterfly valve was successfully installed and has exceeded all performance expectations. It demonstrates how a specialized china butterfly valve supplier can deliver world-class technology, offering an ideal balance of quality and cost-effectiveness for discerning SMEs.
