About This Item

 

Full Description

This API standard specifies the requirements for a heavy-duty series of bolted bonnet steel globe valves for petroleum refinery and related applications where corrosion, erosion and other service conditions would indicate a need for heavy wall sections and large stem diameters.

This standard sets forth the requirements for the following globe valve features:
  • bolted bonnet,
  • outside screw and yoke,
  • rotating rising stems, and nonrotating rising stems,
  • rising handwheels and nonrising handwheels,
  • conventional, y-pattern, right-angle,
  • stop-check (nonreturn type globe valves in which the disc may be positioned against the seat by action of the stem, but is free to rise as a check valve due to flow from under the disc, when the stem is in a full or partially open position),
  • plug, narrow, conical, ball, or guided disc,
  • metallic seating surfaces,
  • flanged or butt-welding ends.

It covers valves of the nominal pipe sizes NPS:
  • 2, 21/2, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 24; corresponding to nominal pipe sizes DN:
  • 50, 65, 80, 100, 150, 200, 250, 300, 350, 400, 450, 500, 600;
