Download the Flowserve Cavitation document here.
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.
The Swanson Flo Blog is dedicated to provide educational and new product information on process control instrumentation, control valves, and valve automation. For more information on these products, visit SwansonFlo.com or call 800-288-7926.

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.

The Basics of Control Valve Actuators
Control Valve (Flowserve Valtek) |
Control valve actuators control fluid in a pipe by varying the orifice size through which the fluid flows. Control valves contain two major components: the valve body and the valve actuator. The valve body provides the fluid connections and a movable restrictor comprised of a valve stem and plug that is in contact with the fluid that varies the flow. The valve actuator is the component that physically moves the restrictor to vary the fluid flow.
The video below introduces the viewer to basic control valve operation concepts and the basic types of actuators.
