Draft Details

1.1  These requirements apply to electrically operated general purpose and safety valves rated 600 volts or less and intended for the control of fluids, such as air, gases, oils, refrigerants, steam, water, and the like. Electrically operated valves, other than automotive fuel valves, covered by these requirements are intended to be used in other than hazardous locations as defined by the National Electrical Code, NFPA 70 and CSA C22.1, Canadian Electrical Code, Part I. For convenience, the shorter term “valve” is used where the same requirements apply to both general-purpose and safety valves.

1.2 This standard also applies to valves intended for marine use per Annexes B, D and F.

1.3 This standard also applies to valves intended for Gasoline and Gasoline/Ethanol Blends with Nominal Ethanol Concentrations Up to 98 Percent (E0 – E98) per Annex C and for marine use per Annex D.

1.4 This standard also applies to valves intended for Diesel Fuel, Biodiesel Fuel, Diesel/Biodiesel Blends with Nominal Biodiesel Concentrations Up To 20 Percent (B20), Kerosene, and Fuel Oil, Biodiesel Fuel Blend Stock (B100) for Middle Distillate Fuels, per Annex E and for marine use per Annex F.

1.4A Valves intended for gasoline/ethanol blends exceeding 10% ethanol (E10) shall additionally comply with Annex C and D as applicable.

1.4B  Valves intended for biodiesel blends exceeding 5% biodiesel (B5) shall additionally comply with Annex E and F as applicable.

1.5  These requirements also apply to electrically operated valves intended to be factory installed on or in certain appliances as operating or safety controls.

1.6 This Standard applies to electrically powered valve actuators* that are designed to be fitted to valves by the end user.

* The term valve includes the valve actuator unless otherwise stated.

1.6A This Standard applies to modulating valves*.

* The term modulating includes inching positioning and continuously modulating unless otherwise stated.

1.7 This Standard applies to self-contained electro-hydraulic actuators, both linear and rotary type. These types of actuators are electrically operated and use hydraulic fluid as a driving medium.

* The term valve includes the electro-hydraulic actuator unless otherwise stated.

1.8 With respect to construction and tests of electrical features, the requirements of this Standard complement those of Row C of Table H.1.

1.9  These requirements do not apply to electrical parts, including coils, switch contacts and resistance elements, located in the flammable liquid or gas containing compartment of a valve.   These components shall comply with the requirements in row A1 of Table H.1, or any other applicable evaluation that shows no hazard will result (giving due consideration to the voltage involved, materials used, construction employed, and the nature of the liquid or gas involved).

1.10  When the valve assembly includes a pressure or flow regulator, its regulating ability is not covered by requirements in this standard.

1.11 When a mechanically actuated indicator is provided to indicate whether the valve is open or closed, its visibility from any distance is not covered by requirements in this standard.

1.12 Valves intended for fire protection service are additionally required to comply with Annex G, Electrically Operated Valves for Fire Protection Service.

1.13 This standard also applies to valves intended for use in fire service systems such as sprinkler systems installed in accordance with the Standard for the Installation of Sprinkler Systems, NFPA 13, per Annex G.

1.14 This Standard contains requirements for electrical and mechanical features of valves that affect their safe operation.

1.15 This standard does not apply to electrically operated damper actuators or similar devices. Those are covered by row A2 of Table H.1.

1.16 This standard does not apply to electrically operated water valves evaluated to row I of Table H.1.

1.17 This Standard does not apply to water valves of connection size larger than 2-inch pipe size or pressure rating above 1600 kPa (232 psi) for valve bodies of thermoplastic material.

Exception: drain valves are excluded from the above.

1.18 The values given in SI units are the units of record for the purposes of this Standard. Where the values are given in parentheses, they are for information and comparison only.

1.19 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.

1.20 This standard also applies to hydraulic control valves installed in elevator systems in accordance with ASME 17.1/CSA B44, Safety Code for Elevators and Escalators.
