Danfoss Introduces Valve for Bent-Axis Motor

Danfoss Power Solutions recently introduced a counterbalance valve for its H1B bent-axis motor, expanding the motor’s application to open-circuit systems.

Specifically designed for the motor, the counterbalance valve enables original equipment manufacturers to harness the benefits of the variable-speed H1B motor, including compact design and efficiency, in high-power drivetrain and winching applications while preventing overspeed and cavitation.

In comparison to competitive offerings, the counterbalance valve for H1B reduces pressure drop, improving system efficiency, and features integrated pressure relief valves, simplifying system integration and reducing time to market. The valve also offers a broad range of options to optimize performance through damping and overall behavior of the main spool, as well as an optional charge port for external charging or system heat-up.

Danfoss H1B motors with counterbalance valve are ideal for wheeled and crawler excavators, crawler and truck cranes, and drilling and pipe handling applications. The DN32 counterbalance valve, available in two versions, fits H1B motors with displacements ranging from 160 to 250 cubic centimeters. A DN25 valve, to be introduced in 2023, will fit H1B motors with displacements ranging from 80 to 110 cc.
