High-pressure hydraulic valves

40 years’ experience for unparalleled performance 
The successive integration of the Auxim and Delta Delage brands gives Ades Technologies group the benefit of 40 years’ experience in hydraulic valve high-pressure solutions.

ADES Technologies group was a pioneer in this field, introducing “between-flange” solutions from the outset, which were adapted to the SAE standard and floating sealing, which have often been copied but still have the technological lead. In addition, special care has also been taken in the design of high-pressure valves up to very large sizes.

Under the Delta Delage brand, these valves with special seals are among the best-performing valves on the market.
