The CeraValve KZT type features a ball design mounted on trunnions, positioned between two seats that are spring-loaded. There is minimal clearance between the ball and the seats, with the upstream seat serving as the primary seal. This configuration enables pressurisation in either direction and allows the valve to function effectively under low differential pressures. Constructed with 304 Stainless Steel for the housing and flanges, there are various material options available for customisation. Additionally, alternative ceramic materials can be chosen in place of the standard Zirconia ball and Alumina seats.
