  • Valve Seat Seal Selection Guide - Flo-Tite
    Ball valves are well suitable for steam service if the material selection and valve design are properly selected However, like all other valves, ball valves are generally rated at a lower pressure for steam service than for liquid or dry gaseous service Steam Rating (PTFE SuperTek) Steam Rating (S-Tek SuperTek III) Steam Rating (RPTFE)
  • Ball Valve Seat Seal Material Selection Guide
    Ball valve seat and seal material specifications: hardness, temperature range, pressure rating, compressive strength for the soft seat ring: PTFE, RPTFE, PEEK, Nylon, Devlon, Molon, etc Seal material: viton AED etc
  • BALL VALVE SEAT-SELECTION - stayflowproducts. com
    Devlon is used in many valve seats which require a broad range of working temperatures, excellent corrosion resistance and outstanding resistance in high pressure applications Temperature Range -50°F to 350°F Carbon Graphite Filled TFM offers exceptional chemical heat resis- tance properties
  • Soft Seat Options for Ball Valves - A-T Controls
    TFMTM-1600 is the standard seat material in Series F9R valves, and Series HP H78 High Purity Ball Valves TFMTM-1600 resists “popcorning” in monomer and polymer services, such as Butadiene because of its lower porosity and permeability compared to PTFE
  • Ball Valve Seat Selection Guide - Triad Process
    When selecting seats, always consult the pressure temperature charts and corrosion resistant guide or contact the factory for engineering help Not all seats are available for use in all our valves PTFE (P) Made from Virgin Teflon, this is the most common sealing material; its chemical compatibility is excellent for almost all media
  • Valve Seats - Valve engineering - Eng-Tips
    I require a 6" 1500# ball valve the current datasheet specification gives the seat material as REINFORCED TEFLON(PTFE + 15% FIBER GLASS) This valve is now obsolete and I'm being offered 2 differing types of replacement
  • L T Valves Process Ball Valves
    L T Ball Valves are available in single-piece, two-piece and three-piece constructions In these valves, line pressure forces the floating ball against the downstream seat to effect bubble-tight sealing Blowout Proof Stem The side-entry stem of L T Ball Valves has a shoulder that bears against a matching shoulder
  • Tech Bulletin Page 180-13 FLO TITE TM Valve Seat Seal Selection Guide
    When equipped with S-Tek or Super-Tek III seats, Flo-Tite valves are good for 250 psig saturated steam Other seat options will bring Flo-Tite valves to higher steam pressure rating, see chart below
  • Ball Valve Seat, Seal, Gasket Material Specifications
    Seat, seal, and gasket material selection guide for ball valves, including application fluid, temperature range, and pressure range, etc The seat is called seat insert in trunnion ball valves , while it is called seat ring in floating ball valves
  • Valve Seat Material Selection for Your Application
    A valve seat is a critical component in a valve that provides a sealing surface for the valve disc or ball, ensuring proper shutoff and flow control It plays a key role in preventing leakage and maintaining the efficiency of a system
