What is the valve trying to do?
What does API 602 say?
Do these two things have anything to do with each other?

My reply to your email (Friday, February 10, 2012 7:46 AM):

• API 600 "Steel Gate Valves-Flanged and Butt-Welding Ends, Bolted and Pressure Seal Bonnets

1.1 Scope

1.1.1 This standard covers steel gate valves with flanged or butt-welding ends in sizes NPS 1 through 24. These sizes correspond to nominal pipe size s in ASME B36.10M.

1.1.2 This standard covers valves in Classes 150 through 2500 as specified in ASME 16.34

1.1.3 This standard covers requirements for a heavy-duty style of bolted bonnet gate valves for petroleum refinery and related applications where corrosion, erosion, and other service conditions indicate a need for full port openings, heavy body wall sections, and large stem diameters. Covered are requirements for outside screw-and-yoke (OS&Y) valves with rising stems, nonrising handwheels, and various types of gate configurations. In addition, Appendix A of this standard covers requirements specifically for pressure seal bonnet gate valves for both a heavy-duty style and a general purpose style for applications where less arduous corrosion and erosion service conditions are confronted or materials are selected so as to ameliorate these conditions.

API 602 "Compact Steel Gate Valves-Flanged, Threaded, Welding, and Extended-Body Ends"

1 Scope

1.1 This standard covers flanged-end, threaded-end, socket-welding-end, and butt-welding compact steel gate valves, including extended-body type, corresponding to nominal pipe sizes in ASME B36.19M as follows:

(a) Flanged-end and butt-welding-end in sizes 4 and smaller,

(b) Threaded-end and socket-welding-end in sizes NPS 2 and smaller. The following valves are specifically covered by this standard:

a. Class 800 valve with threaded, socket-welding, or butt-welding ends

b. Class1500 valve with threaded, socket-welding, butt-welding, or flanged ends; an OS&Y with rising stem and bolted packing-gland flange; and a bolted, welded, or threaded-and-seal-welded bonnet.

c. Class 150, 300, and 600 flanged-end or butt-welding-end OS&Y valves with rising stem; bolted packing-gland flange; and a bolted, welded, or threaded-and-seal-welded bonnet.

d. Class 800 and Class 1500 extended-body valves conforming to items and b above, except with male by female ends in sizes NPS 1/2, 3/4, 1-1/2, and 2 and in size NPS 3/4 male by NPS 1/2 female.

e. Threaded-end male extension for Class 1500 or for size NPS 1/2 in Class 800 are not covered by this standard.

f. Class 150, 300, 600, 800, and 1500 valves with bellows stem seal with the additional requirements covered in Appendix A.
