Without dispensing with the state-of-the-art technology of the BR-B valve, from which it uses the smart solutions as, concave disc with optimized geometry in order to assure high flow rate capacity, self-centering seat ring with soft or metal sealing, and disc stop on the body in order to avoid excess rotation, the BR-B2 Double Offset and the BR-B3 Triple Eccentric lines have been developed to meet industrial application needs at pressure classes ANSI 150 and 300 that can be served by a more standardized eccentric disc valve, with reduced cost and fast delivery, capable to achieve reference performance levels.
