Plug Valves T4E1

The FLOWSERVE DURCO T4E plug valves are designed and developed with the latest technology and therefore very suitable for the chemical process industries and available in the ANSI Class 150 and 300 as well DIN Class PN16 and a maximum temperature of 204°C. The T4E lined plug valves provide maximum corrosion resistance and the elimination of product contamination at reasonable costs. PFA body liner is well anchored against the body by mean of machined and cast T-slots and the solid encapsulated/anchored PFA-plug liner material ensures a strong adhesion. This makes the DURCO T4E plug valve series so suitable for extreme service and vacuum conditions. A large sealing surface guarantees a bubble-tight shut-off. A secondary dynamic self adjusting, self-energized PFA reverse lip diaphragm prevents stem leakage. You never replace valve seats; you only reseat the plug with a quick and easy in-line adjustment. Standard material of construction is ductile cast iron. However, stainless steel valve bodies can be make available upon request. Optional: stainless steel diaphragm support.
