WebSep 13, 2010 · The lack of a balancing valve creates some challenges for the TAB technician. These challenges can be overcome by understanding how PI valves work. There are two types of PI valves, mechanic and electronic. Mechanical valves use a spring-diaphragm pressure regulator and the electronic valves use a flow meter in conjunction …
Pressure independent control valves will often be abbreviated to the letters PICV. This is a type of valve found in Hydronic systems, meaning water based, which provide heating and cooling in buildings. These valves are basically a number of different valves conveniently combined into one unit. This saves … See more There are many variations of this valve.
