Pressure Independent Characterized Control Valve.
Pressure Independent Characterized Control Valve.
(OP)
Does anybody have experience with this new valve?
I would like to include in a new installation, but first I would like to know some opinions, If this kind of valve is a better option? the site is www.belimo.com
Thanks for the help

Is a sustitute for the 3 way valve, the circuit setter and the isolation valves.
Is a two way valve, it gives a specific flow, no matters the pressure variations,
I downloaded a spanish version( yes I'm live at the south of the border)of one power point presentation based in the article "Balancing Variable Flow Hydronic Systems”, Steven T. Taylor y Jeff Stein; del ASHRAE Journal, Octuber 2002. I guess you have more oportunity to get the article
Well, what I need is to know practical experiences and installation tips about it
thanks again and sorry for my imperfect english

While we're talking about it, the article doesn't have any good to say about the automatic balancing valve concept. Anyone have any other experience?

Disadvantages that the autohors state include:
- small orifices in the valves which plug easily, thus requiring strainers (another maintenance item)
- Higher installed cost and operating cost due to higher head required from valves themselves as well as strainers
- The valves are more complex (read: they eventually gonna break)
There generalized conclusion was: use standard control valves and NO balancing.
