  • Rated to ASME 800 limited class for use in all applications requiring 800 limited class ratings or below.
  • Available in 1" nominal pipe size with ⅛", 3/16", ¼" or 5/16" orifice, depending on desired flow capacities.
  • A micrometer dial position indicator allows fast, precise and repeatable settings.
  • Socket weld end connections.
  • Both disc and disc seat are hard faced with Stellite for erosion resistance.
  • Seating surfaces are ground and lapped for tight shut off, eliminating double valving requirements.
  • The integral stem disc is faced with stellite, then ground and lapped for accurate, leak-free sealing.
  • The disc is tapered for maximum controllability over the full stroke of the valve.
  • Standard material is carbon steel (ASME SA 105) body with 13% chrome stainless steel trim.
  • One-piece drop forged body.
  • Graphite packing, complete with braided graphite filament yarn anti-extrusion rings, is standard.
  • All 5505 series valves comply with ASME B 16.34 and the ASME boiler and pressure vessel code, section 1.
