Crane ChemPharma Flow Solutions has introduced a line of Krombach® Metal seated ball valves (MSBV) designed for specialty chemical and mining applications. The valve features a two-piece design with a flange connection.
Krombach MSBV’s ball and seat are machined to such precise tolerances that ball and seat lapping does not have to be performed individually for each valve – making both the ball and seat freely interchangeable (if equal in nominal size). Its trunnion-mounted ball design offers a polygon stem-to-ball connection which reduces stress and ensures optimal torque transmission.
An additional feature is its self-cleaning system which removes excess particles, minimizes leakage, and extends product life. Other key options include a fire-safe design body gasket and removable hand lever.
To ensure that the Krombach MSBV meets the considerably higher benchmark of leak protection required for isolation service, it is typically tested for 60 minutes at 300 psig Nitrogen with a permissible leakage rate of class VI.
