PTFE seats for angle valves

Angle valve seating seal PTFE
We offer the most complete line of valve seats across many industries for ball valve, butterfly valve, angle seat valve, plug valve, diaphragm valve. 
PTFE valve seats provide resistance to aggressive fluids, temperatures and tight sealing.

Material: Virgin PTFE or filled grades of PTFE are available.

Main fillers type and properties please refer to below table:

Filler type
Inorganic filler
Glass fiberUnchanged chemical and electrical characteristics, improve mechanical and wear resistance, but the coefficient of friction is slightly increased, for this reason, need to note the proportion of compounds.
GraphiteImproved thermal conductivity, reduce initial friction and provide general strengthening characteristics, used in compounds for chemical and mechanical service.
BronzeIncreased hardness, best wear resistance, higher compressive modulus and thermal conductivity. But poor electrical characteristics and chemical resistance for itself metallicity.
Carbon fiberLower creep, increase flex and compressive modulus, coefficient of thermal expansion is lowered and thermal conductivity is higher.
MoS2Normally used in small proportions and combined with other fillers like glass and bronze, increase the hardness while decreasing friction. Inert to most chemicals.
Organic filler
PolyimideDecreased friction and high wear resistance, when touches with copper ally and other soft metals, effects actively.



Increased compressive, flexural and mechanical properties. Also improved wear characteristics. Not damage other materials basically.
Polyphenylene   SulfideImproved creep resistance and dimensional stability.
