Ball Valve Seat Materials
Virgin TFE
Virgin TFE is a good all-around, general purpose seating material. TFE has outstanding resistance to chemical attack by a broad spectrum of organic chemicals, inorganic chemicals and solvents and is generally considered chemically inert. TFE is a self lubricating polymer with a very low coefficient of friction, which makes an excellent seating material for quarter-turn ball valves.

Ball Valve Seat Materials (2)
25% Reinforced TFE
Carbon-Filled TFE
Carbon-filled TFE is an excellent seat material for steam applications as well as high efficiency oil-based thermal fluids. Other fillers, including graphite, enable this seat material to have better cycle life than other filled or reinforced TFE seats. Chemical resistance equal to other TFE and filled TFE products.

Color Code Virgin TFE resin has a natural pigment of WHITE. Temperature Range -20oF to +400oF temperature range in ball valve applications. Pressure Range 27" vacuum to 600 PSI non-shock water, oil or gas. Unique Features Best choice for low pressure sealing, lowest torque of all TFE polymers. |
Typical Applications Cold and hot potable water, HVAC chilled and hot water. Evaporative cooling systems |
Color Code 15% reinforced TFE is color coded BLUE. This pigment is permanently molded into the TFE polymer matrix. Temperature Range -20oF to +400oF temperature range in ball valve applications. Pressure Range 27" vacuum to 1,000 PSI non-shock water, oil or gas. Unique Features Greater resistance to cold-flow than virgin TFE. |
Typical Applications Mid-range steam applications. Throttling and balancing of hydraulic heating and cooling systems. |
25% Reinforced TFE
Color Code 25% reinforced TFE resin has a color code of RED. This pigment is permanently molded into the TFE resin matrix. Temperature Range -20oF to +400oF temperature range in ball valve applications. Pressure Range 27" vacuum to 2,000 PSI non-shock water, oil or gas. |
Unique Features Improved dimensional stability. Good wear properties. Typical Applications Steam service, natural and bottled gas distribution. |
Carbon-filled TFE is an excellent seat material for steam applications as well as high efficiency oil-based thermal fluids. Other fillers, including graphite, enable this seat material to have better cycle life than other filled or reinforced TFE seats. Chemical resistance equal to other TFE and filled TFE products.
Color Code Carbon filled TFE has a natural pigment of BLACK. Temperature Range -20¡ã to +500¡ã F temperature range in ball valve applications. Pressure Range 27" vacuum to 2,000 PSI non-shock water, oil or gas. Unique Features Higher cycle life than other TFE resins. |
