Advantages

BIOPRO® forged bodies are manufactured from ASTM A182 GR F316L material with additional controls in regards to chemical content. The sulfur content is maintained to meet and exceed the stringent requirements of BPE. All forgings are solution annealed to maintain the ferrite content to be .05% or less. This low ferrite content eliminates the concern for contaminants and migration of oxides throughout the system. Machining of the contours are performed by using state of the art cad/cam system assuring repeatability of the weir and valve cavity profiles for full drainability. Each forging contains two hash marks clearly indicating the drain angle plane for ease of installation. BIOPRO® forged bodies are in compliance with FDA guidelines as well as cGMP principles, and are specifically designed for use in ultra pure applications where sterility is critical. Top Line provides these bodies with heat numbers etched into them for full traceability. Mill test summaries are provided with each shipment. BIOPRO® forged diaphragm valves are available in sizes ranging from 1/2” through 6” with clamp or weld end connections and surface finishes ranging through 10 RA.
