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;
• pressure seal bonnet;
• outside screw and yoke;
• rotating rising stems and nonrotating rising stems;
• rising handwheels and nonrising handwheels;
• straight pattern, 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, 2½, 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;
