4 offset Butterfly Valves ( Quadruple Eccentric )
(OP)
Hi,
I was wondering if anyone can provide me with manufacturers (name, brand and location) of 4 offset Butterfly Valves - Quadruple Eccentric.
I had Literature of an European manufacturer, however i let a colleague borrow it and is lost. I don't remember the name ether.
I also tried searching on Google without success.
Thank you in advance for your help on this.

I could imagine there being four physical eccentrics, arranged as two pairs, at extremes of the disc and shaft.

it is only six years I'm in the valve business, but I've never heard about Quadruple Offset valve design, me too.
Whatever it is, to me it sounds like a fancy mistake or a marketing invention without much technical meaning...(?)
In any case, many good discussions have been carried out within this Forum about Triple Offset valve design already. See, for example:
- thread408-64692: butterfly valve about the type of design in general;
- thread408-145006: Butterfly valve design: conc, ecc, doubl ecc or triple eccentric? about advantages and disadvantages;
- thread408-135872: The top three sellers for butterfly valve? about the most important Manufacturers;
- thread408-141966: Triple offset butterfly valves for a trouble-shooting case study;
- thread408-149142: Characteristics for triple offset butterfly valve about the control characteristic;
- thread819-149326: Butterfly Sealing Techniques (Metal Seat Type) about the sealing mechanism.
