Proven control valves for cavitation control

14 September 2010

Cavitation with entrained particulate creates a challenging, severe condition for a control valve. If the control valve does not perform as required, your facility could experience unscheduled downtime.

Entrained particulate can shorten control valve life by plugging the cage and causing material erosion of the plug, cage and seat. Cavitation leads to unacceptable noise and vibration, and damage to control valve trim.

Emerson has introduced Fisher® cavitation control technologies ideal for dirty service applications: the Notchflo™ DST control valve, Dirty Service Trim (DST), DST-G control valve, and 461 angle valve. These technologies allow entrained particulate to pass, while resisting cavitation damage in severe liquid flow conditions.

Emerson Process Management application experts can help you select and implement the best Fisher technology for your specific application. There are no force fit solutions. Our expert recommendations are based on the specific challenges and our application experience of severe flow conditions such as catalyst fines in refineries and sand in oil production.

Additional applications in oil & gas production include water injection pump recirculation, produced/wastewater injection well control, separator letdown, and chemical injection pump bypass.
