Overpressure protection in high-power applications

The FHPRV enables machine designers to leverage the benefits of the H1B motor’s compact design and outstanding efficiency while also providing overpressure protection in high-power applications.

The FHPRV is a bolt-on valve that provides high-flow pressure relief at the motor, which is critical for motor protection in demanding applications. In the event of an extended overpressure situation, the valve enables the passage of up to 600 liters per minute of flow, depending on size, preventing damage to the motor and pump. The flow rate is among the highest available for this type of valve.

The compact solution offers full-flow relief functionality without a significant increase in motor size or circuit complexity. Other solutions, such as remote-mount manifolds, require more space and can increase cost and complexity.

Commonly used in closed-circuit propel applications, axial piston motors such as Danfoss H1 motors are also ideal for high-power open-circuit systems, including drilling functions, crushing and shredding functions, heavy-duty excavator attachments, and forestry applications.

The FHPRV can be stacked with other valves, such as the CBV, providing additional functionality based on application needs. It can also be used in closed-circuit applications.
