Description / Abstract:

GENERAL

This standard applies to newly produced manually operated shut-off volves for gas piping systems and constructed of entirely new, unused ports and materials which:

a. are intended for use downstream of the distributors meter or regulator, for operation at a maximum pressure of 1/2 psig (3.4 KPa),

b. are capable of operation at ambient temperatures between 32°F (0°C) and 125°F (52°C) and in addition are also capable of operation at a higher temperature, a lower temperature or both when so specified by the manufacturer.

c. are valves substantially of the plug and body, or rotating disc type, and volves of other types which will provide equivalent performance.

Constructional provisions for spring loaded type manually operated gas shut-off volves are covered in Part 2 "Spring Loaded Type Valves-Construction".

Performance provisions for spring loaded type manually operated gas shut-off valves are covered in Part 3 "Spring Loaded Type Volves Performance,"

Constructional provisions for solid bottom type manually operated gas shut-off valves are covered In Part 4 "Solid Bottom Type Valves-Construction."

Performance provisions for solid a bottom type manually operated gas shut-off valves are covered in Part t 5 "Solid Bottom Type Valves-Performance,

Room temperature. when specified in this standard. shall be considered at 77 + 10°F (25 + 5.6°C).

This standard contains SI (Metric) equivalents to the yard/pound quantities, the purpose being to allow the standard to be used in SI (Metric) units. If a value for o measurement as given in this standard is followed by an equivalent value in other units, the first stated is to be regarded as the requirement. The given equivalent may be approximate. If a value for a measurement and an equivalent value in other units are both specified as a quoted marking requirement. the first stated unit, or both units shall be provided.
