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;
