A new single-stage, four-way hydraulic valve from Danfoss Power Solutions 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.
The KBFRG4-5 proportional valve features what Danfoss describes as 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 step response of 20 milliseconds is also touted as a superior performance capability.
Engineered to withstand the toughest conditions, the KBFRG4-5 proportional valve z 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.
“Vickers has long been the trusted name in industrial hydraulics, and Danfoss will continue to invest in the portfolio to meet the evolving needs of our customers. The KBFRG4-5 proportional valve is just one example. With its robust design, high performance, and advanced features, the valve is an ideal choice for a wide range of demanding applications,” said Dr. Peter Lauer, Global Product Manager, Industrial division, Danfoss Power Solutions.
The KBFRG4-5 proportional valve is offered with tools and features that simplify setup, commissioning, and troubleshooting. The valve features CAN communication and configurable control modes, which can be programmed using Danfoss’ Pro-FX™ Configure software. Optional valve test kits are available to simplify on-site commissioning. The valve’s built-in health monitoring and LED indicator lights simplify diagnostics.
With its round solenoids and external linear variable differential transformer (LVDT) plus standard CETOP 5 body and spools, the valve features a cost-effective design.
Multiple spool options with various flow ratings are available.
The expansive portfolio of Vickers by Danfoss proportional valves offers a wide variety of features and performance levels. From standard performance valves without feedback to servo performance valves with dual motion control, valves are available to meet the demands of a wide variety of industrial hydraulic applications.
