Ball Valve Seats
Our polymer ball valve seats aid in distributing the seating stress uniformly and is usually soft enough to conform to the shape of the ball so that a solid seal is achieved. Ball valve seats involve a collection of material requirements to work correctly. Essential properties include:
All parts are measured on our Zeiss O-Machine and or Keyence CMM, which utilize optical and contact measurement technology in a comprehensive analysis. The O-Machine includes multi-sensor coordinate measuring, white light sensors for non-contact assessments and extremely accurate 3D scanners.
We follow AQL 2.5 levels 1 and 2 sample size quantities, and all molded parts are manufactured to RMA A2 tolerances.
Our rubber and plastic materials supply is diversified amongst the top compounders in North America. Each polymer has been qualified to meet typical exploration and production well conditions, including mechanical, tribological, thermal, and specific immersive properties.

| CFP | Carbon Fiber Filled PTFE– (polytetrafluorethylene) material. It exhibits improved creep and wear resistance. Increased thermal conductivity and low coefficient of friction ensure low wear rate even under dry running conditions. It is suitable for gaskets, valve seals, packings, bearings, and piston rings. | 150°F | 1600 psi | 50.0 % | 1300 psi | |
| GFP | Glass-fibre Filled PTFE. Glass-fibre improves the wear properties of PTFE, lowers the deformation under load at both high and low temperatures, and increases the impact resistance while leaving the electrical and chemical characteristics of PTFE essentially unchanged. It is suitable for piston rings, valve seats, shaft seals, electrical insulators, bearing pads and gaskets. This material should not be used in contact with strong alkalis and hydrofluoric acid. | 150 °F | 1750 psi | 175.0 % | 2600 psi | |
| MGFP | MolyGlass PTFE– a glass fiber and molybdenum disulfide filled polytetrafluorethylene (PTFE). It is used for bushings, bearings, and sealing elements where low creep properties with good sealability and low wear rates are desirable. | 150 °F | 3600 psi | 200.0% | 1800 psi | |
| CGTP | Carbon-graphite Filled PTFE (polytetrafluorethylene) material. Its ability to run under dry or wet conditions along with its low wear rate makes it an ideal high-temperature bearing material. It also offers high load-bearing capability, relative to other fluoropolymers, for many general-purpose industrial applications. | 150 °F | 2300 psi | 105.0 % | 2500 psi | |
| BFP | Bronze-filled PTFE (polytetrafluoroethylene). It provides better creep resistance than most of the PTFE alloys. It possesses high compressive strength and good wear and sliding properties. Most common applications include piston rings (compressors), bushes, bearings, and wear pads for high compression sliding applications. Certain chemicals may easily attack bronze. | 175 °F | 2000 psi | 100.0 % | 1700 psi | |
| MFP | Mica-filled PTFE (polytetrafluorethylene) material. It exhibits very low coefficient of friction and low wear rate under dry running conditions. It is an ideal non-abrasive sealing material against soft metal surfaces in dynamic applications. Compared with other filled PTFE materials, it exhibits excellent sealability at high temperatures. It offers excellent dimensional stability, unparalleled chemical resistance and continuous use temperature of 500 oF. | 210 °F | 2200 psi | 250.0 % | 3000 psi | |
| 1130 | 1130 is a polymer and carbon-filled PTFE (polytetrafluorethylene) material that is significantly softer than VERTEC 1030, but it is a much better sealing material with good wear properties. This material has excellent tensile strength and elongation for PTFE-based materials. This material is specifically designed for demanding sealing/wear applications where PTFE is deemed appropriate. | 150 °F | 2700 psi | 60.0 % | 1500 psi | |
