The CeraValve type KAT features an upstream seat that is spring-loaded. With no clearance between the seats, the ball consistently forms a seal, making it ideal for applications with minimal differential pressure or gradual pressure increase. Crafted from 304 Stainless Steel, the valve housing and flanges offer durability, with the flexibility for various other construction materials. Additionally, alternative ceramic materials beyond the standard Zirconia ball and Alumina seats are also available for selection.
