Butterfly valve seating rings PTFE
Rayflon 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°C
Color: white
RTFE (Reinforced Polytetrafluoroethylene)
RTFE (reinforced Teflon®) is mixed with a percentage of filler material (Glass fiber/ Carbon, 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°C
Color: Gray white or black
