Municipal water supply is the lifeline of every city. From intake and treatment to transmission and distribution, each stage relies on valves for dependable flow control and shut-off. Among all valve types, the butterfly valve has become the most widely used solution for large-diameter water pipelines, thanks to its compact structure, quarter-turn operation, low flow resistance, and easy maintenance.
Why butterfly valves for municipal water systems?
Low pressure loss: Large networks are sensitive to head loss. A fully open butterfly valve offers minimal flow resistance, significantly reducing pumping energy costs.
Reliable bidirectional sealing: Premium seat materials (EPDM/NBR) ensure zero external leakage and protect drinking-water hygiene.
Quarter-turn quick operation: Paired with worm gear, electric, or pneumatic actuators, butterfly valves enable easy remote and automated control.
Lightweight and cost-effective: Far lighter than gate valves at the same size, cutting installation and logistics costs.
