API 6D \/ BS 1868 Flanged Swing Check Valve<\/h2>\n

Yang WDL Valve API 6D tipe swing check valve<\/strong> is designed to allow flow in one direction and automatically prevent reverse flow when the upstream pressure decreases. It protects pumps, compressors and other pipeline equipment from backflow and pressure reversal.<\/p>\n

The valve features a swing-type disc and a straight-through flow passage for low flow resistance. Depending on the selected design and flow direction, it can be installed in horizontal piping or vertical piping with upward flow.<\/p>\n<\/div>\n

Design Features<\/h2>\n
    \n
  • Swing-type disc provides automatic non-return operation.<\/li>\n
  • Saluran aliran langsung membantu mengurangi kehilangan tekanan.<\/li>\n
  • Internal hinge pin construction reduces potential external leakage points.<\/li>\n
  • Bolted cover construction provides convenient inspection and maintenance.<\/li>\n
  • Pressure-seal cover construction is available for Class 900 and higher-pressure configurations.<\/li>\n
  • Renewable or welded seat surfaces are available according to material and service requirements.<\/li>\n
  • RF, RTJ and butt-weld end connections can be supplied.<\/li>\n
  • Carbon steel, stainless steel and special-alloy materials are available.<\/li>\n<\/ul>\n
