Load-holding valve

  • 09-Feb-2011 01:33 EST


Rexroth introduces a concept in load-holding and lowering valves to improve efficiency and control on mobile equipment. Green Valves reduce the need for energy-consuming high-pressure and high oil flow. Engineered to replace traditional counterbalance valves, the design allows gravity to lower the loaded or unloaded boom while increasing stability, control, boom movement, and starting and stopping. Green Valves require little oil flow to lower the boom, so more flow is available for execution of other movements, shortening machine cycle times and improving performance. By using gravity instead of engine power, the valves decrease energy requirements, saving fuel and reducing emissions. Stability and controllability integrated into the valves eliminate the need for damping devices such as orifices, reducing installation space. Compact Green Valves install easily and are suitable for any type of hydraulic circuit.
