Controlling Duct Pressure
application for this product. This article will discuss a typical application - controlling static pressure in a duct by varying fan speed with a Variable Frequency Drive (VFD). This system could also be used to control the pressure with inlet vanes, discharge dampers, bypass dampers, etc. The same
Butterfly Valves in Compressed Air & Vacuum Services
Because a butterfly valve uses a disc to control flow, much like a damper in a duct system, some people occasionally want to use it to control the flow of compressed air and other gases, or for vacuum service. Will it work in these no-liquid applications? For the most part the answer will be yes
Case Study:An Ultra Performing Weather Strip
. Industry: Heating, Ventilation and Air Conditioning (HVAC). Challenges: To improve the sealing performance of weather stripping used on ventilation duct dampers and louvers when exposed to extreme temperatures. To decrease manufacturing costs. To improve delivery lead time. Solutions: Rethink
