PTFE limit Tufline 600 Pressure-temperature ratings. The useful range of PTFE sleeved plug valves is -20°F to +400°F Tufline-475 sleeve: -20°F to +475°F Tufline-600 sleeve: -20°F to +600°F with maximum temperature variation of 200°F. Applications beyond these ranges can be handled effectively but may require valve adjustments at the operating temperature. Material selections are governed by the limits imposed by ASME B16.34, 1996 edition and B16.34a 1998 edition.
