Angle Pattern Gland Packed N230

Angle Pattern Gland Packed N230

Design:

  • API 623 and MSS SP-53
  • Size: 2” to 8 “
  • Connection Type: Flanged or Threaded
  • Bonnet Type: Bolted bonnet or Welded bonnet
  • Stem Sealing:
  • Gland Packing: As the name suggests, gland packed valves utilize compressible materials (like PTFE, graphite, or asbestos) to create a seal around the valve stem.
  • Gland: This is the adjustable fitting that compresses the packing material against the stem, creating a tight seal.
  • Seat Sealing:
  • The primary sealing surface is between the valve plug (or disc) and the valve seat.
  • Materials for these surfaces are carefully selected based on the application and the fluid being handled. Common materials include:
  • Stainless Steel: For general-purpose applications.
  • Stellite: A hard-facing alloy known for its wear resistance, often used in high-temperature or corrosive service.
  • Trim
  • Valve Plug (or Disc): The moving part that controls the flow.
  • Valve Seat: The stationary surface that the plug contacts to create the seal.
  • Stem: The component that connects the plug to the valve operator (e.g., handwheel)
