PTFE Lined Concentric Reducers

Flow-Tech Valves and Engineers  PTFE Lined Concentric Reducers are manufactured in Ductile Iron, Cast Steel and Stainless Steel with PFA, FEP, PVDF and PP Lining having Flanged End connection as per ASME B 16.5 class 150 and DIN dimensions.

Our PFA Lined Concentric Reducer can be supplied with virgin unpigmented liners or static dissipating (Anti-static) liners to prevent static build up within piping on site.

Typically supplied as a transfer moulded PFA lined investment cast steel construction, we use fabrications and PTFE liners for reducers fitted with rotating flanges etc. Reductions by the use of combined reducers and reducing flanges. The overall length would be that of the reducer plus the reducing flange thickness.
