Overview

This guide has been produced to help designers avoid problems with the selection and application of control valves used in hydronic systems. Types of valve covered by the guide include two-port, three-port, four-port and pressure independent control valves.

Proper sizing of control valves is vital to ensure:

  • Comfort Control – to ensure the heating outputs are properly regulated to meet the requirements of the application and thereby avoiding excessive temperature variations in the controlled media.
  • Control of system temperature differential – to maximise the energy efficiencies of low carbon heating and cooling sources by achieving and maintaining the required system temperature deferential under all operating conditions

Selection of Control Valves complements BTS 1/2012 Test Method for Pressure Independent Control Valves by explaining how performance data can be used to assist the selection process and ensure equipment choices are appropriate.

This guide can also be purchased as part of our Hydronic Systems Design Guide Set of 2 that also contains Energy Efficient Pumping Systems (BG 12/2011).
