Series 5200 is designed to provide repeatable control of abrasive or corrosive slurries. The elastomer sleeve produces a smooth venturi flow path and outlasts gate, plug, ball and satellite-coated control valves, according to the company. The sleeve is the only wetted part of the valve, eliminating the need for packing, valve seats and mechanical parts.
