ASTM Valve Seals Ppl Seals

Model NO.: FYV Application: Valve Performance: Temperature Standard: Standard Trademark: FYV Origin: Wenzhou, Zhejiang Material: PTFE Type: Oil Seal Shape: O-Ring Pressure: 150lb-300lb Specification: CE, SGS HS Code: 8481804090 PPL: Added some synthetic material into PTFE, WHOSE performance is better than the pure PTFE. PPL can continuous use at 280 º C, the highest temperature 290-300 º C, low friction coefficient, good wear resistance and excellent chemical stability.


PTFE Product Description:
Excellent chemical resistance and ageing resistance
Fine self-lubrication
Wide usage range of temperature (depends on the specific usage)
Not resistant to radiation
Cold flow(creep under normal temperature)
Instability of size

Application:
150lb-300lb Floating/Fixed Ball Valve seat/sealig ring
The occasion requires corrosion resistance and chemicals
Fillings/gaskets/O-type Ring(-250º C ~260º C )
Sealing ring of other type valves
M-PTFE has better range of elastic deformation and the resistance of cold sprasing.
