The E-valve, by Bosch Rexroth, offers high-performance and fine proportional control for heavy-duty applications like excavators and cranes.

  • Suited for 8-40-ton machines
  • Offers low pressure drop with improved controllability in a standardized, compact package
  • Removal of external hydraulic pilot line provides quicker work cycle times and significant fuel savings
  • Uses electro-proportional pilot stage to control the high-flow metering and speed control of the main stage on load lowering as well as the fine control needed for precise actuator movements
  • Operated via joystick signal and software algorithms
  • Acts as a watchdog in the background, a feature called “Ghost Mode,” is ready to take over and close the valve when a hose burst event is detected
  • Packaged in an optimized 420 bar (6,000 psi) cast housing
  • Weighs 21% less
  • Features 46% lower pressure drop
  • Comes in three cylinder connection sizes, 1/2, 3/4 and 1 in. (1.27, 1.9 and 2.5 cm) SAE code 62 flanges
  • Guarantees very low hysteresis and peaks of pressure in relief function ensuring reduced stress for the cylinders
  • Size options of 2.5 for flow rates up to 250 lpm (66 gpm) and size 5.0 for flow demands up to 500 lpm (132 gpm).
  • With electronic operation, special cut spools are no longer required, offering equipment builders the benefits of hardware standardization and performance to ISO8643 standards
