Butterfly Valve Manufacturer — World-Class Valve Engineering by SVR Global
SVR Global is recognized as a top butterfly valve manufacturer globally, delivering advanced flow control solutions for industrial, municipal, and critical service applications. Our butterfly valves are designed for tight shut-off, minimal pressure drop, and long-term durability, making them a reliable choice for large-diameter pipelines and demanding service environments.
Function & Working
Butterfly valves operate through a quarter-turn disc assembly. When parallel to the flow, the valve is fully open; when perpendicular, it provides complete shut-off. The lightweight, compact design and quick actuation make them highly efficient for isolation and throttling in a wide range of operating conditions.
Advantages
Compact, lightweight construction with reduced installation space
Low torque requirement for smooth quarter-turn operation
Cost-effective solution for large-bore pipelines
Suitable for both shut-off and throttling service
Wide pressure and temperature handling capabilities
Replaceable seats for extended service life
