Brief: Ever wondered how the Sauer PV22 control valve delivers precise hydraulic control for heavy-duty machinery? This video showcases the integrated servo/displacement control module in action, demonstrating its stepless adjustment, pressure protection, and compatibility with Sauer Series 20 piston pumps. Watch to see how it ensures reliability in mining, construction, and industrial applications.
Related Product Features:
  • Integrated servo/displacement control module for Sauer Series 20 swash plate piston pumps.
  • Enables stepless displacement adjustment and pressure protection for precise hydraulic control.
  • Rated for 350bar pressure, suitable for demanding closed-loop hydrostatic drives.
  • Fast response time of ≤0.2s ensures quick and accurate system adjustments.
  • Available in MH, MC, HDC, and HDP variants to meet different control requirements.
  • Designed for use with MHO ISO VG32/46 hydraulic oil in temperatures from -20℃ to 80℃.
  • Robust construction provides vibration and wear resistance for long service life.
  • Ideal for mobile equipment like concrete mixers, loaders, and underground LHD machines.
FAQs:
  • How do I distinguish between the MH, MC, HDC, and HDP variants of the Sauer PV22 control valve?
    MH is a hydromechanical servo control, MC includes pressure compensation, HDC is hydraulic displacement control, and HDP is hydraulic displacement control with pressure compensation. Always verify the nameplate and consult the manual for proper selection.
  • How can high oil temperature affect the performance of the control valve?
    High oil temperature can accelerate seal aging and reduce the valve's response speed and accuracy. It is crucial to maintain oil temperature within the -20℃ to 80℃ range, regularly replace filter elements and oil, and inspect the cooling system to ensure optimal performance.
  • Can the Sauer PV22 control valve be upgraded to electro-hydraulic proportional control?
    Yes, by adding a proportional servo valve or an electro-hydraulic converter, the valve can support 4-20mA or 0-10V control signals. This upgrade requires adjusting the pump control logic and parameters and is recommended to be performed by OEM or authorized service providers.
