CAN/CSA-E730-2-8-94 PDF Download

CAN/CSA-E730-2-8-94 is a standard that lays out the specific specifications for electrically operated water valves. It covers home appliances and related devices that utilize electricity, gas, oil, solid fuel, solar thermal energy, or a combination of these. The standard covers electrically operated water valves for appliances covered by IEC 335 as well as electrically operated water valves used in heating, cooling, and related applications.

The standard specifies standards for the mechanical and electrical elements of water valves that affect how they are supposed to function. The testing of automatic electrical controls used in household and comparable equipment, operating values, operating sequences related to equipment protection, and intrinsic safety are all covered. Additionally, it consists of electrically powered valves for machinery utilized by the general public in stores, small businesses, and farms.

The electrically driven water valves created specifically for industrial purposes—those with a nominal connection size above DN 50, those with an allowable nominal pressure rating above 1.6 MPa, food dispensers, detergent dispensers, and steam valves—are exempt from the standard's requirements.

Certain terms used in the document are defined in the standard, including "valve" to refer to an electrically operated water valve, "actuator" to denote an electrically operated mechanism or prime mover, "valve body" to denote the valve body assembly, and "equipment" to include appliances and control systems.

The standard also applies to valve bodies and actuators that are made to fit together. Additionally, it includes valves that are employed singly or as a component of a system and that are mechanically connected to multipurpose controls with non-electric outputs.

The standard notes that water authorities or businesses may create extra test requirements and bylaws in various nations.
