IEC 60730-2-8:2018+AMD1:2021 CSV
Automatic electrical controls - Part 2-8: Particular requirements for electrically operated water valves, including mechanical requirements
- electrically operated water valves of nominal connection size above DN 50;
- electrically operated water valves for admissible nominal pressure rating above 1,6 MPa;
- food dispensers;
- detergent dispensers;
- steam valves;
- electrically operated water valves designed exclusively for industrial applications. This document applies to electrically operated water valves, responsive to or controlling such characteristics as temperature, pressure, passage of time, humidity, light, electrostatic effects, flow, or liquid level, current, voltage, acceleration, or combinations thereof. This document also applies to actuators and to valve bodies which are designed to be fitted to each other. This document applies to individual valves, valves utilized as part of a system and valves mechanically integral with multi-functional controls having non-electrical outputs. This document applies to AC or DC powered electrically operated water valves with a rated voltage not exceeding 690 V AC or 600 V DC. This document does not take into account the response value of an automatic action of a valve, if such a response value is dependent upon the method of mounting the valve in the equipment. Where a response value is of significant purpose for the protection of the user, or surroundings, the value defined in the appropriate equipment standard or as determined by the manufacturer shall apply. This document applies also to electrically operated water valves incorporating electronic devices, requirements for which are contained in Annex H. This document applies also to electrically operated water valves using NTC or PTC thermistors, requirements for which are contained in Annex J. This document applies to the electrical and functional safety of electrically operated water valves capable of receiving and responding to communications signals, including signals for power billing rate and demand response. The signals can be transmitted to or received from external units being part of the valve (wired), or to and from external units which are not part of the valve (wireless) under test. This document does not address the integrity of the output.
