Scope

These requirements cover 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. These requirements also cover electrically operated valves intended to be factory installed on or in certain appliances as operating or safety controls. These requirements do not cover general purpose valves that are not intended to be used with a flammable or hazardous fluid and are intended only for connection to a low voltage circuit of limited power supplied by a primary battery or a separate external Class 2 transformer. However, if a high-voltage transformer with a low-voltage secondary is incorporated as an integral part of a valve, the assembly is covered by these requirements. These requirements do not cover valves for use in hydraulic fluid power systems. These requirements do not cover valves covered by the requirements in the Standard for Automatic Valves for Gas Appliances, IAS/AGA Z21.21.
