Product Introduction
Sanitary welded butterfly valve features a stainless steel body and disc,
along with a sanitary sealing design, and connects directly to sanitary piping via butt-welding.
The disc rotates approximately 90° around the stem:- 0° — Fully Closed
- 90° — Fully Open
- Intermediate Position — Flow Regulation
Sanitary butterfly valves are primarily used for on/off operation, isolation, and partial flow control in sanitary fluid piping systems.
Compared to Tri-Clamp butterfly valves, the key characteristic of the welded type is:The valve-to-pipe connection is permanently welded, eliminating external clamp joints at the valve ends.
Consequently, it is particularly well-suited for systems requiring continuous piping, high levels of cleanliness, and fewer detachable connection points.

Why is "welding" important for sanitary butterfly valves?
Tri-Clamp:
Valve → Ferrule → Gasket → Clamp → Pipe
Involves a detachable connection.
Weld End:
Valve → Weld → Pipe
Directly welded.
This approach reduces:
External connectors
Gasket interfaces
Potential leak points
Risk of external contamination
Connection points requiring periodic disassembly for maintenance
