DSI® cast steel valves are designed and manufactured for petroleum refineries, chemical processing, power generation, pulp & paper and other applications for both conventional and cryogenic service. All flanged DSI® cast steel valves come standard with 125-250 RA flange finishes. DSI® utilizes flexible graphite packing, a variety of gasket materials and exacting assembly and testing procedures to ensure compliance with the world’s emissions control standards. These valves are NACE MR0175/MR0103 compliant and are available in a wide variety of materials and exotic alloys. DSI® cast steal gate, globe and check valves are designed and manufactured to ensure leakage of less than 100 ppm (parts per million) of volatile organic compounds.
