Proven control valves for cavitation control

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.
