Triple offset butterfly valve

Today, come to work on Monday, arrived when the company heard colleagues sitting together discussing what, then listened for a while before I make out what they’re talking about (electric cylinder), the beginning I did not know this Triple offset butterfly valve is something, talk to them I did not get it, but then after a while I only understand a little bit, as if to give our warehouse to install this Triple offset butterfly valve, and I also they say that if you listen to our company installed later this Triple offset butterfly valve, what to do when the job a lot easier. I did not expect a Triple offset butterfly valve is still very strong.
