Moog Hydrolux

Moog Site in the Heart of Luxembourg

Specializing in Applications, Integrated Hydraulic Manifold Systems, Cartridge Valve Technology, and Pilot Valves

Moog Integrated Hydraulic Manifold Systems:

With 35 years of history in the field, cartridge valves (also known as 2/2-way logic valves, or slip-in elements) have a proven role in hydraulic applications. Some advantages commonly recognized over other technological solutions are compact design, quick response and tight sealing. Compared to subplate-mounted valves, cartridge valves are available in bigger sizes having much greater flow capacities.

Moog Hydrolux has developed vast experience with this product line, helping customers to find solutions on a variety of applications. Innovations have continued to improve this product and offer even greater functionality. For example, the open/close functionality is today state-of-the-art. Through creativity, excellence in design and manufacturing, and extensive field experience, Moog has developed a product range of cartridge families that incorporate the most modern control techniques.

Moog acquired the well-known company Hydrolux in 1998, to provide even better hydraulic motion control expertise to customers. Cartridge valve technology continues to be a focus of product development and process optimization. By combining Moog’s high performance servo and proportional valve products with integrated hydraulic manifold systems it is possible to provide leading OEM’s worldwide with the best control solutions from components to systems. In addition, a range of products is available from small to large power.

Cartridge Valve Technology:

Today, Moog Hydrolux provides cartridge technology with many related components such as covers and pilot valves (e.g. directional, check, and pressure functions). The product range includes:

  • Standard Cartridge Valves (DIN) - Please note: DIN designates a 2/2-way cartridge valve according to DIN 24342 or ISO7368.
  • High Flow Cartridge Valves (DIN) with 35% to 50% more flow than Standard Cartridge at the same pressure drop
  • Active Cartridge Valves (DIN)
  • Monitored Cartridge Valves (DIN) for Press Safety
  • Servocartridge Valves (DIN and Hydrolux standard)

Sizes for all of these products range from NG10 to NG160 with flow ranges at 5 bar [72 psi] pressure drop from 70 lpm [18.5 gpm] NG10 up to 20,000 lpm [5,300 gpm] NG160. The hydraulic valve program is one of the most complete worldwide in terms of functionality, variety, and nominal size.


  • High flow capability, far above the "subplate valves"
  • Insensitivity to high pressure drops
  • Same cavity for all functions simplifies manufacturing
  • Low flow resistance
  • Compact installation - multi function, sized to match the flow path
  • Multi-function - same device can control direction, pressure and flow

Integrated Hydraulic Manifold Systems:

Another important capability of Moog Hydrolux is the design of hydraulic manifold blocks based on vast experience in many applications. Manifold systems up to a weight of 6500 kg (14,346 lb) can be manufactured onsite or subcontracted to other facilities.

Sample of Applications Experience:

  • Injection Molding Machines
  • Blow Molding Machines
  • Die Casting Machines
  • Presses
  • Metal Forming Machines
  • Heavy Industry Machines
  • Paper Machines
  • Scrap Shear and Presses
  • Windmills

The Future:

We are pleased to announce that in 2005 Moog Hydrolux will leave its present location in the heart of Luxembourg City and move to new building in Luxembourg Bettembourg in order to take advantage of the ability to expand and develop more efficient operations. As always, Moog is focused on the evolution of our technology and sharing our know-how with customers to find the best solution to their problems.
