Rexroth continues its leadership in mobile control technology by integrating the best of both worlds: high-tech M4 Series sectional valves combined in a single assembly with its modular ED family of compact directional valves. The performance requirement of any given machine function can now be perfectly matched to each valve section’s performance and price.
With its M4 technology and lower-cost, flow-rate-specific ED valve sections, Rexroth created a hybrid solution that addresses machine functions requiring high precision with high-flow output, as well as low-flow or low-precision functions such as stabilizers, counterweight lifts and locking pins.
While mobile applications require diverse flow rates for varying functions, Bosch Rexroth’s sectional control solutions match the right valve to the required flow. This means the hydraulic system can be fully optimized, potentially reducing the size and cost of components and helping to satisfy increasing requests from manufacturers for total machine weight reduction. At the same time, this assures overall cost effectiveness because valve sections are sized for a specific functional requirement; over-sized valve sections are a thing of the past.
The Rexroth ED family of modular directional valves contains both proportional and switching valves, load-sense, and standard functions, with valve sections sized for maximum flow rates from 4 to 20 gallons per minute and operating pressures up to 4,500 pounds per square inch. All ED Series valve sizes share a common mounting interface and can be combined in any order. Downstream stacking modules such as pressure controls, flow controls and load-holding elements further enhance the flexibility of this modular product line. When these options are further applied across six different flow-rate optimized proportional controls, the combinations are nearly limitless.
