CSA C22.2 No. 139-13 (R2018)

This Standard applies to electrically operated, general-purpose valves* and safety valves* that are intended to be used in ordinary locations in accordance with the Canadian Electrical Code, Part I, for the control of fluids (e.g., air, gases, oils, refrigerants, steam, water, etc.), and rated 600 V and less.
* For convenience, the shorter term "valve" is used where the same requirements apply to both general-purpose and safety valves.
