PTFE Lined 90 Degree Elbow

PTFE Lined 90 Degree Elbow Manufacturer

MVS Valves PTFE Lined 90° Elbow is a precision-engineered solution for smooth directional change in highly corrosive process pipelines. Manufactured with a seamless virgin PTFE or PFA liner and housed in a robust ductile iron or carbon steel body, this elbow ensures long-lasting protection against chemical attack, permeation, and corrosion fatigue. It is available in sizes ranging from ½″ to 24″ (DN 15–600), designed to ANSI Class 150/300 or PN 10–25 pressure ratings, and operates efficiently within a broad temperature range of –40 °C to +230 °C.

Our PTFE Lined 90 Degree Elbow features raised face flanges and is fully compliant with global piping standards such as ASTM F1545, ASME B16.9, and ISO. All elbows up to 150 mm are provided as cast fittings, while larger sizes are fabricated. The lining is done using paste-extruded PTFE liners that are flared over the flange face to ensure leak-proof sealing. Additionally, FEP and PFA mouldings are standardized for cast elbows to maximize chemical resistance and durability. For sensitive applications, these elbows are also available in anti-static PTFE liners, preventing the build-up of static charges in volatile media handling.

Applications of PTFE Lined 90 Degree Elbow
