Overview

EN IEC 60730-2-8:2020/A1:2021 is a European standard developed by the CLC (European Committee for Electrotechnical Standardization) that specifies particular requirements for electrically operated water valves, including their mechanical aspects. This standard serves as an amendment (A1) to the base standard EN IEC 60730-2-8:2020, updating and enhancing the safety, reliability, and performance criteria specifically for automatic electrical controls applied to water valves.

The document is integral to the field of automatic electrical controls and focuses on the safe design, testing, and operation of electrically operated water valves used primarily for household and general-purpose applications. It aligns with IEC 60730-1 and is intended to be implemented nationally across European countries, ensuring harmonization and compliance with electrotechnical requirements.

Key Topics

• Scope and Applicability:
  Covers automatic electrical controls for electrically operated water valves, including the mechanical design requirements necessary for safe operation.

• Mechanical Requirements:
  Detailed specifications for torque testing, mechanical endurance, and materials standards (e.g., steel grades per ISO 630-2:2011) ensure valves operate reliably under expected conditions.

• Thermal and Electrical Safety:
  Defines temperature limitations for winding insulation classes during overload and blocked conditions to prevent motor burnout or hazardous failures.

• Terminals and Connections:
  Requirements for terminals and terminations cover internal and external wiring connections, including support for special connectors (ISO 4400, ISO 6952) and pilot duty loads.

• Abnormal Operation Tests:
  Rigorously tests valves for blocked mechanical output scenarios, abnormal temperature conditions, and electrical overloads to ensure durability and user safety.

• Harmonization with IEC 60730-1:
  This part 2-8 standard is designed to work in conjunction with IEC 60730-1, the general standard for automatic electrical controls, thereby providing a comprehensive compliance framework.

Applications

• Household Water Control Systems:
  Electrically actuated valves used in domestic water heaters, boilers, and heating systems benefit from this standard to ensure safe and efficient performance.

• HVAC and Plumbing Systems:
  Used in heating, ventilation, and air conditioning equipment where precise water flow control via electrically operated valves is critical.

• Industrial and Commercial Water Control:
  Applicable to electrically controlled water valves in industrial processes requiring reliable automatic control with safety guarantees.

• Smart Building Automation:
  Valves conforming to EN IEC 60730-2-8 support integration into smart control systems for water management and energy efficiency.

Related Standards

• IEC 60730-1:
  General requirements for automatic electrical controls, which EN IEC 60730-2-8 complements with specific provisions for water valves.

• ISO 630-2:2011:
  Technical delivery conditions for structural steels used in valve construction, ensuring appropriate material strength and durability.

• ISO 4400 and ISO 6952:
  Standards covering special connector types used in terminals and wiring of electrically operated water valves.

• Other Parts of IEC 60730:
  Relevant for controls of different applications such as motors, pumps, and household appliances, providing a holistic framework for automatic control devices.

---

Adherence to EN IEC 60730-2-8:2020/A1:2021 guarantees the mechanical robustness, electrical safety, and functional reliability of electrically operated water valves, crucial for manufacturers, designers, and compliance assessors in the electrotechnical and water control domains. This standard fosters uniform safety practices and facilitates market access across Europe by harmonizing national regulations with international electrotechnical requirements.
