Erreesse has its own in-house testing department: all inspections and tests are performed by qualified and experienced personnel


Quality is a word that embodies a world of meanings, all with a positive connotation; unfortunately, an abuse of this term leads us today to a sterile document but, Quality cannot exist without Passion.

Our quality is not only the use of raw materials and components certified for origin and duration over time; not only the search for stable and efficient suppliers who share the same standards as Erreesse. Our concept of quality goes hand in hand with Research and Improvement. We will never tire of seeking Perfection.

The largest test bench in Europe

ERREESSE owns the largest test bench in Europe to perform in safety conditions hydrostatic, pneumatic and high pressure gas testing on valves up to 72”. This test bench has an official capacity of 4000 tons with a very maximum capacity of 6000 served by a 100 tons overhead crane.
