Rexroth A4VTG 71 90 HW Manual Control Valve A4VG71 90 HW100 HW200 for Mixer Trucks

1. Product Overview

This product isRexroth A4VTG/A4VG series hydraulic pumps specially designed for concrete mixer trucksand its supportingHW series manual control valves. This combination is thecore power unitof the hydraulic drive system of concrete mixer trucks. It is responsible for converting the engine's power into hydraulic energy to drive the mixing drum for actions such as loading, mixing, agitation, and unloading.

2. Core Features

• Designed specifically for mixer truck working conditions: The A4VTG/A4VG series pumps are optimized for the characteristics of frequent start - stop, large load fluctuations, and harsh working environments of mixer trucks. They feature high reliability, long service life, and good low - speed stability.

  
  

• Flexible variable control: Through the supportingHW series manual control valves (e.g., HW100, HW200), the driver can easily achieve theforward rotation (mixing), reverse rotation (unloading), and stopof the mixing drum in the cab, and can perform stepless adjustment of the rotation speed. The operation is simple and intuitive.

  
  

• High - efficiency and energy - saving: It uses an advanced variable adjustment mechanism, which can automatically adjust the output displacement according to the actual load of the mixing drum, effectively reducing energy consumption, engine load, and fuel consumption.

  
  

• Sturdy structure and easy maintenance: The pump body is made of high - strength materials, and the key friction pairs are specially treated, with strong wear resistance. The HW manual control valve has a mature structure, low failure rate, and is convenient for daily inspection and maintenance.
