The ultimate dirty service trim

Fisher® Dirty Service Trim from Emerson is a multi-stage anti-cavitation trim ideal for use with many control valves. DST is used in severe services where fluid may have entrained particulate capable of plugging passages or causing erosion damage to conventional anti-cavitation trims.   Typically, the trim is used in high pressure drop applications up to 290 bar in the chemical, refining, oil and gas production and power industries.   DST uses a combined axial and radial flow path that features large openings, allowing particulate up to 19mm to pass through. It is available with up to 6-stage trim, and with a globe or angle body.
