VOLZ
  • Offer Profile
  • Hydraulic connectors in carbon steel and stainless steel
    Only a handful of manufacturers serve the market segment of tube couplings and connections for hydraulic systems. All of them are specialists. So are we. However, the Volz Group offers products both in carbon and stainless steel. And this, combined with the breadth and depth of our production, is unique amongst suppliers producing in Germany.

    In addition to our solutions for tube couplings and connections, Volz has made a name for itself as a market leader in the field of balls for ball valves. So you will find our balls in many ball valves of all pressure ranges.
