New KBFRG4-5 industrial hydraulic valve from Danfoss Power Solutions delivers high power capacity, superior durability

NORDBORG, Denmark – Danfoss Power Solutions today announced the expansion of its Vickers® by Danfoss portfolio of proportional valves with the launch of the KBFRG4-5 valve. The new single-stage, four-way hydraulic valve features a round solenoid design and delivers high power capacity and superior durability. The valve is designed for a range of industrial applications, including wind turbines, machine tools, plastic molding, metal forming, pulp and paper processing, and more. 

The KBFRG4-5 proportional valve features a market-leading maximum pressure rating of 350 bar and a maximum flow of 290 liters per minute at 57 bar, delivering higher power capacities than other valves on the market. Its competitive step response of 20 milliseconds further adds to its superior performance capabilities. 

Engineered to withstand the toughest conditions, the KBFRG4-5 proportional valve features an IP67 ingress protection rating and a robust metal housing for increased vibration and shock resistance (7.8 g random, 50 g shock). A high corrosion resistance option is also available. The valve complies with industry standard certifications, including CE, UKCA, REACH, RoHS, and EMI/EMC.

The KBFRG4-5 proportional valve is offered with tools and features that simplify setup, commissioning, and troubleshooting.
