How do ball valves compare to diaphragm valves in piping/system design?
Ball valves are widely used in process applications because of their inherent versatility. Diaphragm valves offer a limited service range for temperature and pressure and do not meet all of the standards for industrial valves. Ball valves are available for: Cryogenic serviceHigh temperature / Low temperature High velocity / Low velocityHigh pressure / Low pressure Wider range of seat materialsWider range of body materials Wider range of end connectionsFire-safe designs • In addition, ball valve center sections are removable to allow access to the inner weld bead where cleaning and/or polishing may then be performed. • What is drainability? Drainability is important for maintaining bioprocess systems in a clean and sterile condition. Fluid remaining after draining becomes a colonization site for bacteria or other microorganisms creating an unacceptable bioburden to the system. Sites where fluid accumulates also may become a corrosion-initiation site adding additional contaminants to the
