Sanitary Weld Butterfly-type ball valve
Forged from high-quality SS304/SS316L stainless steel, KINGMAN Sanitary Weld Butterfly-type ball valve features integrated butt-weld ends for seamless pipeline connection. It eliminates extra pipe fittings and leakage risks, suitable for long-term continuous operation. The valve inner cavity is finely processed by CNC precision turning with high precision and no residual dead space, resisting repeated CIP cleaning and high-temperature SIP sterilization. The streamlined disc handle saves installation space and ensures stable operation. Multiple FDA-compliant sealing materials are optional. It is widely applied in high-standard pipelines such as biopharmaceutical, precision clean fluid and long-cycle liquid cooling systems.

Working Principle
The Sanitary Weld Butterfly-type ball valve controls fluid on/off by 90° rotation of the ball. The butt-weld construction forms a rigid integrated piping system after welded to pipelines. Rotating the stem drives the ball to rotate coaxially. Media flows through when the ball bore aligns with the flow channel. After 90° rotation, the solid surface of the ball presses against the seat to shut off fluid. The inner cavity is CNC precision turned with streamlined flow path to minimize turbulence and support CIP/SIP cleaning & sterilization. Permanent welded connection eliminates loose joint risks, ideal for continuous closed sanitary piping with stable pressure holding and zero leakage.
Why Choose KINGMAN
Weld-End Fit Review
