DR Pilot-Operated Pressure Reducing Valve Some functions introduction

  • Pressure Application:Pressure is applied to channel A, which acts on the lower side of the main spool.Simultaneously, pressure is applied to the spring-loaded side of the main spool via nozzle and to the ball in the pilot control valve via channel.The pressure also acts via nozzle, control line, check valve, and nozzle on the ball.
  • Free Flow and Check Valve:For free flow back from channel A to channel B, an optional check valve can be installed.A pressure gauge connection allows monitoring of the reduced pressure in channel A.
  • Equilibrium State:The equilibrium state is when the pressure in channel A is balanced with the pressure set at the spring. This is achieved by the control spool adjusting its position to either allow or restrict the flow from channel B to channel A, maintaining the desired reduced pressure.

Rexroth DR Pilot-Operated Pressure Reducing Valve - Technical Specifications

Hydraulic Fluid Temperature Range:

  • NBR seals: -30°C to +80°C.
  • FKM seals: -20°C to +80°C.

Viscosity Range:

  • 10 to 800 mm²/s.

Notes on Hydraulic Fluid:

  • Suitability: For hydraulic systems, the cleanliness classes stated for the components are necessary. Where the components are well filtered, faults are kept off,, ensuring their life cycles are lengthened.

Bio-degradable and Flame-resistant Fluids:

  • Dissolved zinc in biodegradable fluids and water fluids can rapidly age hydraulic fluid.
  • A chemical reaction may produce zinc soap, which can clog filters, nozzles, and solenoid valves, especially with local heating up.
  • Compared with mineral oil HLP, the lifespan of a component for flame-resistant fluids containing water may be reduced by up to 30% due to greater cavitation tendency. It is recommended that return flow pressure at ports T be backed up to about 20% of the differential pressure at the component.
