Understanding Cavitation in Valves
According to Wikipedia, "Cavitation is the formation of vapor cavities in a liquid, small liquid-free zones ("bubbles" or "voids"), that are the consequence of forces acting upon the liquid. It usually occurs when a liquid is subjected to rapid changes of pressure that cause the formation of cavities in the liquid where the pressure is relatively low. When subjected to higher pressure, the voids implode and can generate an intense shock wave."
Cavitation presents serious concerns to engineers and specifiers of control valves. Understanding ways to mitigate cavitation is important. Flowserve has put together this excellent document on understanding cavitation and offers solutions on reducing or eliminating its effects.
Comprehensive Steam in Place (SIP) Whitepaper Available
Steriflow, a manufacturer of high purity control valves, pressure regulators, piping specialties, and steam specialties has authored a comprehensive overview of SIP, including existing components, piping design, and the new technology used to reduce common problem occurrences.What are the rules and common piping practices employed to ensure that steam sterilization occurs on time without fail? What are SIP temperature validation alarms, or faults? Why do they occur? How does thermostatic steam trap operation affect the occurrence of temperature validation faults? What new technologies are available to mitigate common SIP problems? Specific answers to these questions will be covered in this white paper.
