Product Introduction
Welded butterfly valves are industrial shut-off valves with welded end connections, suitable for opening and closing media and flow control in pipeline systems.
Product Features
Fully welded valve end structure reduces flange connection points and lowers the risk of pipeline leakage.
Precise fit between the butterfly plate and valve seat ensures smooth opening and closing torque and uniform sealing.
Short valve body design occupies little installation space, suitable for compact pipeline layouts.
