Recommendation:<\/strong><\/p>\n

    \n
  • \n

    Water treatment?<\/strong>\u00a0\u2192\u00a0Wafer or Lug (EPDM seat).<\/strong><\/p>\n<\/li>\n

  • \n

    Oil & gas?<\/strong>\u00a0\u2192\u00a0Triple-offset (metal seat, fire-safe).<\/strong><\/p>\n<\/li>\n<\/ul>\n

    \n

    2. Material Selection (Body & Disc)<\/strong><\/h2>\n
    \n\n\n\n\n\n\n\n\n\n
    Material<\/strong><\/th>\nFluid Compatibility<\/strong><\/th>\nMax Temp<\/strong><\/th>\nApplications<\/strong><\/th>\n<\/tr>\n<\/thead>\n
    Cast Iron<\/strong><\/td>\nWater, air<\/td>\n250\u00b0C<\/td>\nHVAC, general purpose<\/td>\n<\/tr>\n
    Ductile Iron<\/strong><\/td>\nWater, mild chemicals<\/td>\n350\u00b0C<\/td>\nWater distribution<\/td>\n<\/tr>\n
    Stainless Steel (CF8M\/316SS)<\/strong><\/td>\nCorrosive fluids<\/td>\n600\u00b0C<\/td>\nChemical, marine<\/td>\n<\/tr>\n

    Key Tip:<\/strong><\/p>\n

      \n
    • \n

      For corrosive fluids (acids, chlorine), use PTFE-lined SS valves.<\/strong><\/p>\n<\/li>\n<\/ul>\n

      \n

      3. Seat Material (Sealing Performance)<\/strong><\/h2>\n
      \n\n\n\n\n\n\n\n\n
      Seat Type<\/strong><\/th>\nLeakage Class<\/strong><\/th>\nMax Temp<\/strong><\/th>\nBest For<\/strong><\/th>\n<\/tr>\n<\/thead>\n
      EPDM Rubber<\/strong><\/td>\nClass VI (bubble-tight)<\/td>\n120\u00b0C<\/td>\nWater, air<\/td>\n<\/tr>\n

      Critical Choice:<\/strong><\/p>\n

        \n
      • \n

        Zero leakage?<\/strong>\u00a0\u2192\u00a0PTFE or EPDM.<\/strong><\/p>\n<\/li>\n

      • \n

        Fire-safe?<\/strong>\u00a0\u2192\u00a0Metal seat (API 607 certified).<\/strong><\/p>\n<\/li>\n<\/ul>\n

        \n

        4. Actuation Method<\/strong><\/h2>\n
        \n\n\n\n\n\n\n\n\n\n
        Actuator Type<\/strong><\/th>\nOperation<\/strong><\/th>\nBest For<\/strong><\/th>\n<\/tr>\n<\/thead>\n
        Lever\/HANDWHEEL<\/strong><\/td>\nManual, quarter-turn<\/td>\nSmall valves, low torque<\/td>\n<\/tr>\n
        Gear Operator<\/strong><\/td>\nManual, high torque<\/td>\nLarge valves (\u226512″)<\/td>\n<\/tr>\n
        Pneumatic<\/strong><\/td>\nAutomated, fast response<\/td>\nFrequent cycling<\/td>\n<\/tr>\n

        Hydraulic<\/strong><\/td>\nHigh-force applications<\/td>\nOffshore, heavy industry<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

        Rule of Thumb:<\/strong><\/p>\n

          \n
        • \n

          Valves > 12″ usually need gear or actuators.<\/strong><\/p>\n<\/li>\n<\/ul>\n

          \n

          5. Pressure & Temperature Limits<\/strong><\/h2>\n
            \n
          • \n

            Check ASME B16.34 ratings<\/strong>\u00a0for your valve\u2019s\u00a0pressure class (e.g., 150, 300, 600 PSI).<\/strong><\/p>\n<\/li>\n

          • \n

            Example:<\/strong><\/p>\n

              \n
            • \n

              EPDM seat<\/strong>\u00a0\u2192 Max\u00a0150 PSI @ 120\u00b0C.<\/strong><\/p>\n<\/li>\n

            • \n

              Metal seat<\/strong>\u00a0\u2192 Up to\u00a01,450 PSI @ 600\u00b0C.<\/strong><\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

              Always derate for high temperatures!<\/strong><\/p>\n

              \n

              6. Certifications & Standards<\/strong><\/h2>\n
