Guide to selecting control valves

UK: The topic of control valves, how they work and how to size and select them, is covered in a new technical guide from the Building Controls Industry Association (BCIA).
The new guide, simply titled Selection of Control Valves, is intended to provide a better understanding of the complex topic of control valves in HVAC systems. It was put together after feedback from customers and installers suggested this subject needed a simple introduction guide.
The BCIA argues that with today’s focus on the electronics side of the controls, it is easy to neglect the importance of proper valve selection and application.
The topic of hydraulics in HVAC systems has changed considerably in recent times as affordable technology has enabled variable flow circuits and pressure independent control (PIC) valves.
“We may remember that there are many things to be considered when selecting a control valve but valve design, technology and application has changed in recent times,” commented BCIA president Terry Sharp. “This Guide provides some basic clarity to the novice and serves as an aide-memoir to the more experienced and will hopefully help HVAC engineers be more confident in their valve selection.”
