Manually Operated Gas Valves For Use In Fuel Piping

.1

This Standard applies to newly produced manually operated metallic gas shut-off valves, hereinafter referred to as valves, constructed entirely of new, unused parts and materials which:

a) are for indoor/outdoor installation;

b) are for use in the gas piping between the outlet of the gas distributor's meter and the inlet connection of the pressure regulator installed upstream of the manual valve in the gas piping to each appliance;

c) are capable of operation at ambient temperatures between 32oF to 125oF (0 oC to 52 oC) if intended for indoor use only, or temperatures between -40oF to 180oF (-40 oC to 82 oC) if intended for indoor/outdoor use.

d) are to be rated for either 2 psig (14 kPa) or 5 psig (35 kPa); and

e) include sizes 1/4 through 4 inch NPS and tubing sizes ¼ in through 1 inch O.D.

1.2

A valve covered under this Standard is for use with natural gas, manufactured gas, or propane gas.

1.3

This Standard sets forth the minimum capabilities, characteristics, and properties which a valve must possess, at the time of manufacture, in order to be considered suitable for use in an indoor/outdoor gas piping system. Details of design and manufacture, other than those stated in this Standard, including such design and production tests that will produce a valve that will have the required capabilities to meet the Standard, remain the responsibility of the manufacturer.

1.4

All references to pressure throughout this Standard are to be considered gauge pressures, unless otherwise specified.

1.5

This Standard contains SI (Metric) corresponding to the yard/pound quantities, the purpose being to allow the standard to be used in SI (Metric) units. (IEEE/ASTM SI 10, American National Standard for Metric Practice, or ISO 80000-1:2009, Quantities and units– Part 1: General, is used as a guide in making metric conversion from yard/pound quantities.) If a value for a measurement and a corresponding value in other units are stated, the first stated value is to be regarded as the requirement. The given corresponding value may be approximate. If a value for a measurement and a corresponding value in other units are both specified as a quoted

marking requirement, the first stated unit, or both shall be provided.

1.6

In this Standard, “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; and “may” is used to express an option or that which is permissible within the limits of the Standard.

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.
