- Scope
- 1.1 These requirements cover valves that are intended to be used for the control of flammable and
combustible liquids and their vapors. They are of the type commonly used in piping systems and in the
assembly of motor fuel dispensing and fuel burning equipment. Valves covered by this standard are for
use with flammable liquids which are handled at temperatures normally within the range of -29°C (-20°F)
to 52°C (125°F).
1.2 These requirements cover valves of the manually operated, pressure operated, or temperature
operated types, or combinations of such to the exclusion of types operated wholly or partially by electricity.
When they form a part of an assembly which provides for additional functions or service, the requirements
are outside the scope of these requirements.
1.3 These requirements do not cover the following:
a) Valves for handling liquids under cryogenic conditions.
b) Valves for general refinery service, offshore and pipe line terminals, natural gas processing
plants, gas distribution systems, petrochemical processing facilities, or the like.
c) Constant-level oil valves and electrically operated valves.
d) Relief valves and pressure regulators for liquefied petroleum gas (LP-Gas) service.
e) Shutoff, emergency shutoff and check valves for liquefied petroleum gas (LP-Gas) in the liquid
phase.
f) Manually operated gas valves of the plug and body or rotating disc type which are evaluated
under the Standard for Manually Operated Gas Valves for Appliances, Appliance Connector Valves
and Hose End Valves, ANSI Z21.15.
g) Valves covered by the Standard for Gas Appliance Pressure Regulators, ANSI Z21.18; the
Standard for Automatic Valves for Gas Appliances, ANSI Z21.21; or the Standard for Gas
Appliance Thermostats, ANSI Z21.23.
h) Hose nozzles covered by UL 2586 Hose Nozzle Valves or CAN/ULC-S620 Hose Nozzle Valves.
i) Valves covered by the Standard for Manually Operated Metallic Gas Valves for Use in Gas Piping
Systems up to 125 PSI (Sizes NPS 1/2 through NPS 2), ANSI/ASME B16.33; and Manually
Operated Metallic Gas Valves for Use in Aboveground Piping Systems up to 5 PSI ANSI/ASME
B16.44.
1.4 Products covered by this Standard are intended to be installed and used in accordance with the
applicable Codes and Regulations as determined by the Authority Having Jurisdiction (AHJ), such as, but
not limited to:
a) In the United States:
1) Flammable and Combustible Liquids Code, NFPA 30;
2) Code for Motor Fuel Dispensing Facilities and Garages, NFPA 30A;
3) Standard for the Installation of Oil-Burning Equipment, NFPA 31.
B) In Canada:
1) The National Fire Code of Canada; and or
2) CSA B139, Installation Code for Oil Burning Equipment;
3) Provincial or other Regulations.
