Add-on Valves for H1 Motors

Where to buy

Taking H1 Motors to even more applications

Danfoss is pleased to offer a variety of add-on valves for our family of H1B bent-axis motors, expanding the motor’s application to open-circuit systems. 

Our CBVs (counterbalance valves) enhance 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.

The new FHPRV (full-flow high pressure relief valve) is a bolt-on valve that provides overpressure protection in high-power applications.

Danfoss Power Solutions H1B with Counterbalance Valves

Take Danfoss' proven H1B bent-axis motors to open-circuit propel applications with our CBV (counterbalance valve) solution. Ideal for when propel isn't the machine's primary function, but when smooth travel and controlled braking are required.

Features and benefits

Counterbalance Valves:

  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

 

FHPRV:

  1. Provides high-flow pressure relief at the motor - critical for motor protection in demanding applications
  2. Prevents damage to the motor and pump during extended overpressure situations
  3. Full-flow relief functionality without a significant increase in motor size or circuit complexity
  4. Can be used in either closed-circuit or open-circuit applications

Our 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)
