BS EN ISO 5210:1996 is a British Standard that has been adopted from the International Organization for Standardization (ISO) standard ISO 5210. This standard pertains to industrial valves and specifically addresses the requirements for multi-turn valve actuator attachments.
In essence, this standard provides guidelines and specifications for the design, dimensions, and mounting of multi-turn valve actuators on industrial valves. Multi-turn valve actuators are devices used to operate valves that require multiple complete rotations (turns) to fully open or close, such as gate valves and globe valves.
The standard covers various aspects related to the interface between the valve actuator and the valve itself. It includes information about the dimensions and tolerances of the attachment interface to ensure compatibility between different valve types and actuator manufacturers. The goal is to facilitate the interchangeability of valve actuators and valves, which is particularly important for maintenance and replacement purposes.
Key topics covered by BS EN ISO 5210:1996 include:
Definitions and terminology related to valve actuators.
Designations and markings for different types of valve actuators.
Mounting flange dimensions and characteristics for attaching actuators to valves.
Key dimensions and tolerances for ensuring proper fit between actuators and valves.
Guidelines for the attachment of actuators to valves, including fixing methods and hardware.
It's important to note that standards can be subject to updates and revisions, so the information provided here is based on the version available up until my last knowledge update in September 2021. For the most current and accurate information, you should refer to the official British Standards Institution (BSI) or International Organization for Standardization (ISO) sources.
