Low Temperature Ball Valves – Erreesse Srl Valves
Low Temperature Ball Valves: ball valves for temperature range from 0° to -29°C (32° to -20,2°F) can have soft seated construction with a wide range of possible thermoplastic inserts (Devlon V, Nylon, RPTFE, PEEK, PCTFE) and elastomer seals O-ring (FKM, FFKM, HNBR, EPDM, FEPM); particular care should be given to Charpy Impact testing of carbon steel, low temperature carbon steel and ferritic, martensitic and duplex alloys to verify that selected material is suitable for required minimum design temperature; carbon steel and low temperature carbon steel, stainless steel and duplex materials are acceptable if suitable to other service conditions and pressure ratings.
