Description / Abstract:

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.

This Standard also applies to valves intended to be incorporated into equipment that is subject to the requirements of the Canadian Electrical Code, Part II.

This Standard also applies to electrically powered mechanisms that are designed to provide the signals needed for monitoring valve operation from a remote location and to electrically powered valve actuators*, that are designed to be fitted to valves.

* For convenience the term valve includes valve actuator unless otherwise stated.

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

This Standard does not include requirements for mechanical and operational features that do not directly affect the safe operation of a valve.

With respect to construction and tests of electrical features, the requirements of this Standard complement those of ANSI Z21.21/CSA 6.5. 

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.

Electrically operated damper actuators are evaluated to the requirements of CSA C22.2 No. 24.

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

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 (nonmandatory) to define their application.
