Applications
Suitable for chemical plant, marine pipeline, seawater treatment, metallurgy and waste incineration system. Used for shut‑off and throttling control of corrosive gas, high‑temperature flue gas, salt‑containing medium and abrasive fluid.
Working Principle
Stainless Steel Metal Seated Butterfly Valve completes opening and closing by 90‑degree rotation of stainless steel disc. When disc is parallel to pipeline, medium flows through; rotating 90 degrees makes disc tightly press metal seat to realize tight shut‑off. Stainless steel material prevents chemical corrosion, metal hard‑seat guarantees reliable sealing under high‑temperature abrasive conditions.
