Hydraulic Control Valve for A11VO145/190LG1DS Axial Piston Pump

Product Overview

This Hydraulic Control Valve is the matched regulator valve for A11VO145/190LG1DS axial piston pump, a core component of the hydraulic system on heavy-duty construction Machine. It works together with the main hydraulic pump to adjust displacement and output pressure dynamically. The valve precisely controls pump flow and pressure according to load changes, stabilizing the whole hydraulic system and protecting the axial piston pump from overload damage.

Specially designed for Rexroth A11VO series pump A11VO145/190LG1DS, this control valve is a direct replacement spare part. It adopts high-precision valve spool and premium sealing parts, delivering reliable regulating performance under continuous high-pressure working conditions for engineering Machine.

Technical Specifications

- Product Name: Hydraulic Control Valve for A11VO145/190LG1DS Axial Piston Pump

- Matching Pump Model: A11VO145/190LG1DS Axial Piston Pump

- Product Type: Pump Regulator / Hydraulic Control Valve

- Working Medium: Anti-wear hydraulic mineral oil

- Rated Pressure: High pressure matching A11VO pump

- Feature: Load sensing & pressure cut-off control

- Application: Main pump regulation of construction Machine

- Fitment: Direct replacement, no extra modification required

Working Principle

Installed on the A11VO axial piston hydraulic pump, this hydraulic control valve receives pressure signal feedback from the hydraulic system. When the load of the Machine rises or falls, the internal spool of the control valve moves automatically, adjusting the swashplate angle of the piston pump. It changes pump displacement to increase or reduce oil flow, realizing load-sensing power matching. Once pressure exceeds the preset limit, the valve will cut off pressure output to prevent overload failure of the hydraulic system.

Core Advantages

1. Original mounting dimension, perfectly compatible with A11VO145/190LG1DS axial piston hydraulic pump, simple installation.

2. Precision machined valve spool, sensitive response, low internal leakage, stable regulation for the hydraulic system.

3. High quality seals, good resistance to high pressure, impact and vibration, suitable for tough construction site environment of the Machine.

4. Integrated load sensing and pressure limiting function, optimize power output and reduce energy consumption.

5. Cost-effective aftermarket spare part for pump overhaul, widely used by repair shops and global spare parts dealers.

Application Range

This hydraulic control valve is used as regulator of A11VO145/190LG1DS axial piston hydraulic pump. It is widely equipped in excavators, concrete pump trucks and other heavy construction Machine, serving for maintenance and replacement of the whole hydraulic system.
