Introducing the stainless steel "KM200 type" and the cast iron "C201R type" butterfly valves!
We would like to introduce our "2 products" of butterfly valves! The stainless steel high-performance butterfly valve "KM200" is designed to accommodate a wide range of fluids with its reinforced PTFE seat. The drive shaft of the disc is double-eccentric, ensuring that the disc and seat remain non-contact until just before fully closed, resulting in minimal wear on the seat and a long lifespan. The cast iron butterfly valve "C201R" features a concentric contact surface on the seat, creating a self-sealing mechanism that generates contact pressure on the sealing surface of the disc due to fluid pressure, allowing for effective sealing from vacuum to high pressure. For more details, please refer to the related products and catalog, or feel free to contact us. 【Product Lineup】 ■ KM200: Stainless steel high-performance butterfly valve ■ C201R: Cast iron butterfly valve *For more details, please refer to the related products and catalog, or feel free to contact us.
