Take H1B to open circuit applications

Introducing a new counterbalance valve CBV for our family of H1B bent-axis motors, expanding the motor’s application to open-circuit systems. The new CBV enhances system performance by improving system efficiency, and features reduced pressure drop, integrated pressure relief valves, simplifying system integration and reducing time-to-market. 

Choose DN25A for 80 and 110cc H1B, DN32A for the 160cc, or DN32B for 210 and 250cc.

Features and benefits

  1. H1B + CBV: aligned designs and proven technology to generate the perfect match – with quick and easy installation
  2. Longer spool stroke, resulting in higher performance and smoother reaction
  3. Highly flexible and configurable due to the variety of spool and damping characteristics – this means precise and repeatable control – and optimized productivity
  4. Integrated brake release for the external brake and anti-cavitation valve – modularity enabling fast adaption and customization when needed
  5. Reduced pressure drop rates gives your machine increased efficiency and improved energy efficiency


Our counterbalance valves are ideal for a wide variety of systems:

  • Wheeled and crawler excavators
  • Crawler and truck cranes
  • Drilling and pipe-handling applications
  • Rotating attachments (e.g., rotary tiller)
