PTFE Seating Rings For Butterfly Valve
Butterfly valve seating rings PTFERayflon is specialized in manufacturing and exporting various valve seats and seals made from high quality PTFE and filled PTFE.PTFE or Teflon® as it is commonly known is a fluorocarbon based polymer and is usually the most chemically-resistant of all plastics while retaining excellent thermal and electrical insulation properties. This material is non-contaminating and accepted by many agencies for use in food services. It is used as a seat material in many steam and high temperature & pressure solenoid valves as well as some of ball valves and butterfly valves.Temperature range: -10°C to 120°CColor: whiteRTFE (Reinforced Polytetrafluoroethylene)RTFE (reinforced Teflon®) is mixed with a percentage of filler material (Glass fiber/ Carbon,Website:, Graphite) to provide additional strength, stability and resistance to abrasive wear, and less permeation. This reinforcement permits higher pressures and temperatures than unfilled PTFE. Temperature range: -20°C to 180°CColor: Gray white or black
