Rexroth R901377826 Pressure Reducing Valve FTDRE 4 K1X/30AG24N0K40V - 8 Excavator Parts

1. Product Overview

This product isRexroth FTDRE series three - way pressure reducing valve with proportional solenoid.This valve is in the hydraulic system of the excavator.A key pilot control elementused to "reduce the pressure" of the relatively high system pressure and stabilize it at a lower value, which serves as the pilot control pressure for subsequent hydraulic valves (such as the main control valve) to achieve precise proportional control.

2. Core Features

• Proportional control and precise pressure reduction: Different from traditional on - off pressure reducing valves, the FTDRE series isa proportional pressure reducing valve. By inputting an analog electrical signal (such as 0 - 10V or 4 - 20mA), it canlinearly and steplessly adjust the output pressure, thus achieving fine control of the speed and force of the actuating elements (such as cylinders and motors), which is the key for the excavator to achieve "micro - motion" and "compound actions".

  
  

• Three - way design, energy - saving and efficient: With a three - way structure, the excess flow can directly flow back to the oil tank instead of generating heat through the throttle valve port. Therefore,it generates less heat and has high system efficiency.

  
  

• Integrated electronic components, rapid response: The valve integratesa proportional solenoid and a displacement feedback sensor (such as the "K40V" in the model), forming a closed - loop control to ensure that the spool position is precisely controllable. It responds very quickly to the input signal and operates smoothly without impact.
