Block Cylinder Comparison—Vega V450 CM and AHP Merkle BZ 500

There is a strange taboo in Europe, which is absent in the USA—that of comparative advertising about hydraulic cylinders.

In fact, even to simply list the major differences between products from different manufacturers can be considered offensive. But strangely enough, it seems there are no problems when it comes to comparing cars, bikes or other everyday items.

That is why Vega decided to start writing these articles, so as to give our customers and agents further insight on several specific products.

Such articles are meant to be helpful in choosing the most suitable cylinder for your applications!
