Hamai BSS-22 Series Stainless Steel Butterfly Handle Ball Valve (08A~15A)<\/span><\/strong><\/h3>\n
Compact Design for High Reliability in Tight Spaces<\/span><\/strong><\/div>\n

Core Advantages<\/span><\/strong><\/h4>\n
    \n
  • Designed for Narrow Spaces:<\/span><\/strong>\u00a0Features a compact butterfly\/wing handle, perfectly suited for narrow piping layouts and integration into small-scale equipment.<\/span><\/li>\n
  • One-Piece Forged Body:<\/span><\/strong>\u00a0The main body utilizes stainless steel extrusion technology (with certain components extruded). Its seamless structure significantly minimizes external leakage risks and effectively prevents cracking at threaded connections compared to traditional cast products.<\/span><\/li>\n
  • Hexagonal Body:<\/span><\/strong>\u00a0Excellent machinability makes it highly adaptable for various equipment and industrial facility piping systems.<\/span><\/li>\n<\/ul>\n

    Key Features<\/span><\/strong><\/h4>\n
      \n
    1. Superior Sealing Reliability<\/span><\/strong>\n
        \n
      • All sealing components utilize corrosion-resistant PTFE (glass fiber reinforced).<\/span><\/li>\n
      • A conical spring (disc spring) leverages both medium pressure and elastic force to enhance sealing performance.<\/span><\/li>\n
      • An internally embedded stem design completely eliminates the risk of fluid spillage.<\/span><\/li>\n<\/ul>\n<\/li>\n
      • Ease of Operation<\/span><\/strong>\n
          \n
        • Simple 90\u00b0 handle rotation for opening\/closing; the handle position provides a clear visual indication of the valve status.<\/span><\/li>\n<\/ul>\n<\/li>\n
        • Premium Materials & Craftsmanship<\/span><\/strong>\n
            \n
          • Main body\/key components: Made from SUS316 stainless steel via extrusion (not casting), offering superior crack resistance.<\/span><\/li>\n
          • Handle materials: Chrome-plated die-cast zinc alloy (ZDC2) for sizes \u226415A; Vinyl-coated SUS430 stainless steel for sizes \u226520A.<\/span><\/li>\n<\/ul>\n<\/li>\n
          • Special Variants<\/span><\/strong>\n
              \n
            • Oil-free versions compatible with Hamai standard grades are available (Models: BSS-217\/273\/857).<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ol>\n

              Operational Limitations & Precautions<\/span><\/strong><\/h4>\n
                \n
              • Low-Temperature Installation:<\/span><\/strong>\u00a0For sizes 08A and 10A, ensure the fluid enters from the end cap side during low-temperature operations.<\/span><\/li>\n
              • Risk Warning:<\/span><\/strong>\u00a0Please consult us in advance if there is any risk of liquid vaporization inside the valve, water freezing, or abnormal pressure increases due to swelling.<\/span><\/li>\n
              • Detailed Ratings:<\/span><\/strong>\u00a0Refer to the PT rating table for comprehensive temperature and pressure specifications.<\/span><\/li>\n<\/ul>\n
