General

This Standard covers steel valves primarily intended for use in oil or gas pipeline systems. The following types of valves are covered:

gate valves;

plug valves;

ball valves; and

check valves.

Size, nominal pressure class, and category

Size

This Standard covers valves in sizes from NPS 2 to NPS 60. (See Table A.1.)

Nominal pressure class

This Standard covers valves having cold working-pressure ratings designated by nominal pressure classes from PN 20 to PN 420. The standard nominal pressure classes are shown in Table 1. (ASME class designations are shown in Table B.1.)

Category

This Standard covers valves in the following categories:

Category I: valves without requirements for proven notch-toughness properties; and

Category II: valves with requirements for proven notch-toughness properties.

End configuration

This Standard covers standard end requirements for flanged, buttwelding, and wafer-type valves. Other end configurations are considered non-standard and are subject to agreement between the purchaser and the manufacturer.

Terminology

In CSA Standards, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; "may" is used to express an option or that which is permissible within the limits of the standard; and "can" is used to express possibility or capability. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
