Flowserve Durco Plug Valves
Flowserve's Durco range of lined plug valves offers robust solutions for demanding corrosive applications. The T4E series features PFA-lined bodies and comes in three standard configurations: the T4E2 (DIN) with face-to-face dimensions per DIN EN 558 Series 1 and flanges per DIN EN 1092-2 PN16 from DN 15 to DN 150; the T4E1 (ANSI) with a short ASME B16.10 pattern and ASME B16.5 Class 150 flanges from ½" to 14"; and the T4E3 (ANSI) with an ASME B16.10 pattern and ASME B16.5 Class 300 flanges from ½" to 12"; all feature a reduced bore. For high-purity services, the Sleeveline G4 series eliminates the cavity. The G4E (ANSI) combines a DIN EN 558-1 face-to-face with DIN EN 1092-2 PN40 flanges (DN 15-150). The G411 (ANSI) and G431 (ANSI) models follow ASME B16.10 dimensions with Class 150 and Class 300 flanges per ASME B16.5, respectively, both ranging from ½" to 8" with a reduced bore.
