Case Study: Reliable Butterfly Valves in a European Municipal Water Supply Project

Background

In 2024, a European city embarked on a major municipal water supply upgrade to improve the reliability and efficiency of its pipeline network. The project aimed to modernize the system, which serves more than 200,000 residents, ensuring a consistent and safe water supply for the growing population.

The city required large-diameter butterfly valves and resilient seated gate valves that could withstand continuous operation, provide tight sealing, and allow for easy on-site maintenance.

Challenges

• High demand for leak-free sealing in large-diameter pipelines

• Need for long service life under continuous water supply operation

• On-site maintenance and replacement flexibility to minimize downtime

• Compliance with European municipal water standards

Our Solution

Our engineering team supplied a combination of Flanged Butterfly Valves and Resilient Seated Gate Valves, specifically designed for municipal water pipeline applications.

Flanged Butterfly Valve – Ideal for large-diameter pipelines, offering compact design, low torque operation, and tight shut-off.
Resilient Seated Gate Valve – Ensures bubble-tight sealing and easy operation for critical sections of the water distribution system.

Both valve types were manufactured with high-grade ductile iron body, epoxy coating for corrosion resistance, and replaceable sealing elements to extend service life.

Results & Benefits

After installation, the valves demonstrated outstanding performance:

Leak-free operation – Prevented water loss and improved system efficiency
Easy maintenance – Reduced downtime and minimized maintenance costs
Reliable supply – Ensured consistent water delivery to over 200,000 residents
Long service life – Robust design suitable for long-term municipal applications

Customer Feedback

The municipal engineering department expressed high satisfaction, highlighting the valves’ durability, reliable sealing performance, and easy field serviceability as key advantages.

Conclusion

This project showcases how our butterfly valves and gate valves play a vital role in municipal water supply infrastructure. By delivering safe, durable, and efficient flow control solutions, we help cities around the world provide residents with reliable access to clean water.
