DUAL PLATE WAFER TYPE CHECK VALVE

SAILENT FEATURES:

  • Wafer Type Design, thus taking lesser space than the conventional
    Check Valve.
  • Being light in weight, is more rigid that the standard Swing Type Check
    Valve, which otherwise needs expensive foundation and special supports.
  • Being cylindrical in body, stresses are uniformly distributed.
  • Can be installed in Vertical or Horizontal pipe lines.
  • Much longer seat life because of Bronze / S.S to Rubber contact.
  • Low wear and tear of seat surfaces.
  • End connections are designed to suit flanges drilled to ANSI B Class-125
    / Class-150.
