Components for BAC Control Loops - Valve and actuator assemblies - Part 1: Water-based HVAC applications prEN 17691-1

Scope

This document specifies requirements and test methods for valve-actuator assemblies in individual zone control of water-based HVAC applications.

Where a certain control loop as a combination of controller, Valve-Actuator assembly is assessed under EN 15500, this standard allows the assessment of the performance of combinations of that controller with different valve-actuator assemblies. The tests in this document ensure that valve-actuator assemblies as components of certified control loops based on EN 15500 can be replaced with products that assure the achievement of a comparable or better performance.
