This document specifies requirements and test methods of valve-actuator assemblies in individual zone control of water-based HVAC applications.
This document does not apply to control valves of nominal diameter larger than DN50.
This document is applicable to pressure independent and pressure dependent control valve-actuator assemblies of relevant categories: 2-port, 3-port and 6-port valves (if they incorporate a control valve function).
Where a certain control loop as a combination of controller and valve-actuator assembly was assessed under EN 15500-1 [3], this document 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 control loops, can be replaced with products that provide comparable or better performance.
In hydronic system, valve-actuator assembly is a component of control loop that controls water flow rate according to the application control demand.
