(OP)
Is Zwick Tri-Con valves the best on the Market. I have read that this triple offset buterfly valve has zero leakage.

If we learn from our mistakes I'm getting a great education!
RE: Zwick Valves
Best = Total cost over lifetime (buying, installing, maintenance and final preparing for new replacement valve) divided by total lifetime.
All compared for different valvetypes for the special application at the special location at the special plant!
With this I am sure that your valve will not be best for any application anywhere. (And perhaps even not for yours??? - And I am really for the use of high-quality valves)
RE: Zwick Valves
Lets determine whether this is now going to an offshore platform fabrication yard, a construction job site, etc. Those folks normally have to perform pipe leakage testing. Let's assume that those guys often use dirty water to fill the pipe. Assume that sometimes they let lots of water sit (or ship) within various headers etc. for a long time.
Guess the percentage of valves, whether triple offset, gate, ball etc. no longer pass a zero leakage test. I don't know the official details etc. My experience with this problem related to an offshore platform where I participated as a support engineer for over two-years in another country. Although involved, I did not head any engineers, construction technicians, commissioning or other startup type folks. All kinds of tricks were tried mostly with ball valves to move the closed position just enough that they worked. I cannot verify but my memory would suggest about 75-80% of the valves (mostly ball) were not zero leakage during commissioning and startup.

Do you have a question or are you just trying to promote Zwick valves?
