ITT Engineered Valves
Pure-Flo Bypass Valve
The Pure-Flo Bypass valve optimizes fill rate of large vessels used in WFI storage, media hold and buffer preparation by combining two flow paths: a larger main valve for fast filling and a smaller bypass valve for slow, precise top-off. Standard valve sizes run 0.5-2 inch (DN15-50) with a 0.25 inch (DN8) bypass of 0.18 inch internal diameter. Bodies are always wrought and are compatible with standard Pure-Flo topworks.
