Product Details

Rayflon provides a series of high quality ball valve seats made of virgin PTFE (Polytetrafluoroethylene) and reinforced PTFE (RPTFE).

Virgin and Reinforced PTFE valve seats mainly used in following application:
1.150lb～300lb floating/ fixed ball valve
2.Where there is a requirement for chemical and corrosion resistance
3.Long term using temperature:-100℃～120℃(Virgin PTFE), -100℃～150℃(RPTFE)
Reinforced PTFE has better resistance to wear and deformation under heat and load, better cold flow resistance, compressive strength, increased hardness, but tensile strength, impact strength, elongation at break, insulation, resistance to corrosion and non stick property decreased.
TFM® is a chemically modified PTFE that offers enhanced properties which retaining all the proved advantages of conventional PTFE. FDA grade. ideal for semi-conductor and high purity service.

Materials selection in ball valve seats according to different pressure, temperature, media, etc as below:
Virgin PTFE( Conventional &modified PTFE)- White color
