1. Product Overview

This is a product specially designed forRexroth A4VG series variable piston pumps(covering displacements such as 125, 140, 180, 250, etc.) supportingIntegrated pressure control valve assembly. It is usually installed on the rear end cover or regulator of the pump, integratingHigh-pressure relief valve(Main safety valve) andLow-pressure relief valve(Charge relief valve or control pressure valve), and it is a key component to protect the pump body safety and maintain the system pressure.

2. Core Features

• System integrated design: Specifically customized for the A4VG pump, it is directly installed on the reserved interface of the pump, with a compact structure, no additional pipelines are required, and the response speed is fast.

  
  

• High pressure rating: Using high-strength materials and precision machining, it can withstand the high working pressure of the A4VG pump (usually up to over 450 bar) to ensure system safety.

  
  

• Accurate pressure setting: The spool and valve seat are precisely matched, and the pressure-flow characteristic curve is stable, which can effectively prevent pressure overshoot or fluctuation and ensure the smooth operation of the equipment.
