A major municipality was facing a critical issue with its aging water distribution network. The system, fitted with decades-old gate valves and failing low-quality butterfly valves, was plagued by persistent leaks. This resulted in significant non-revenue water (NRW) losses, high maintenance costs from frequent repairs, and an increasing risk of service disruptions to residents and businesses. The city needed a reliable, long-term solution from a butterfly valve supplier who could provide a durable, tight-sealing valve butterfly valve engineered for longevity in municipal water applications.
A Custom-Engineered Solution Rooted in Foundry Expertise
Leveraging our unique position as a source butterfly valve factory, JRVAL delivered a tailored solution that addressed the client's needs for quality, performance, and budget, perfectly suiting small and medium-sized enterprises or municipal entities seeking high-value equipment.
Superior Casting & Guaranteed Materials
Our company was built on a foundation of casting excellence, with our founder being a casting expert. For this project, we utilized high-grade ductile iron for the butterfly valve casting, producing robust bodies with epoxy coatings for maximum corrosion resistance. The integrity of every industrial butterfly valve starts with the raw material, and we guarantee that our materials conform to the exact international standards specified by the client, whether it's an ASME valve or a DIN valve.
Precision Valve Machining for a Perfect Fit
A key advantage we offer is specialized, custom-dimension machining. Our precise valve machining ensures every butterfly valve provides a seamless 'drop-in' replacement for old, non-standard units. This precision, compliant with API 609 butterfly valve standards, dramatically reduced on-site installation time and labor costs. We supplied both wafer type butterfly valve models for installation between existing flanges and lug type butterfly valve units for dead-end service, all with a guaranteed perfect fit. The clear difference between lug and wafer type butterfly valve options allowed for optimal placement throughout the network.
The Right Valve Technology for Each Application
Our team specified a range of valves for optimal system performance. Large diameter mains (e.g., 12 inch butterfly valve, 24 inch butterfly valve) were fitted with a butterfly valve with worm gear for easy, controlled operation. Smaller lines used the simple and efficient butterfly valve lever operated model. We chose an EPDM seat butterfly valve, guaranteeing compliance with potable water safety standards and providing bubble-tight sealing. For higher pressure zones, our double eccentric butterfly valve design was used to reduce seat wear and lower operating torque, ensuring a longer service life. We also provided high-quality wafer check valve units to prevent backflow and protect the system.
Results: Unprecedented Reliability and Economic Value
The JRVAL solution has been a resounding success. The new installation has transformed the city's water network, drastically cutting losses and operational overhead. This project highlights the significant economic benefits of investing in high-quality, properly engineered valve solutions.
