PTFE/PFA/PEEK/PVDF/PCTFE Molded Ball Valve Seats | DCW

Ball Valve Seats

Seats and inserts, which are important components in the valve industry, as a critical component, PTFE is very often to choose as the raw material. PTFE provides a low friction seat, with excellent media compatibility. Filled grades provide wear resistance and can support seating loads of the higher class of valves.
