    The Durco T4E Lined Plug Valves are Class 150 and 300 fluoropolymer-lined valves specifically designed for corrosive services. These valves feature a thick, continuous PFA liner locked to the body by T-slots, ensuring that all wetted parts are covered and eliminating the need for high alloy materials in the body. The plug is PFA-encapsulated, with the covering extending up the stem through the top cap. These bidirectional valves provide drop-tight shut-off, independent of line pressure, and are equipped with primary and secondary seals to prevent leakage.
