The following seat materials are available.MaterialFeaturesMaximum Service TemperatureVirgin PTFEHigh chemical resistance and operation efficiency200℃HYPATITE® PTFEMonomer permeability is lower and resistance against compression and creeping is higher than other PTFE materials260℃/270℃*1Carbon filled PTFEExcellent heat and abrasion resistance260℃/270℃*1FILLTITE®*Highest heat resistance among PTFE based materials300℃*2GraphiteExcellent for high temperature service500℃MetalExcellent for high tempe Wide service temperature range of −29°C (-20°F) through 270°C (518°F) SCTDZ/UTDZ(M) Series, 260°C (500°F) UTB and SCTAZ/UTAZ(M) Series.This is for standard valve design and materials used for medium to high temperature services. The lower temperature range can be extended down to −196°C (-321°F) by means of extended bonnet design and special low temperature service materials.High chemical resistance comparable to virgin PTFE.Monomer permeability lower than other PTFE materials.High mechanical st Highest heat resistance among PTFE based materials.Service temperature range: -29°C to 300°CTrim symbol: 1H Metal seated ball valves are guaranteed for a maximum service temperature of 300°C (572°F) (Trim symbol 5H) and 500°C (932°F) (Trim symbol 6H*1*2). For hard graphite seated ball valves, a maximum service temperature of 500°C (932°F) is also guaranteed (Trim symbol 3H*2). Heat resistant sealing and trim materials qualify these valves for heated and abrasive service which cannot be properl
