A11VO190/260 Integrated Control Valve Pilot Hydraulic Control For Metallurgical Equipment

Product Introduction

This integrated control valve for Rexroth A11VO190/260 swashplate axial piston pumps integrates constant power (LR), pressure cut-off, load-sensing (LS) and differential pressure compensation, designed for open circuits. With a rated pressure of 350 bar and peak pressure of 400 bar, it adopts pilot hydraulic control to achieve stepless displacement adjustment from 0 to Vgmax, accurately matching high-power pump operating conditions and providing stable pressure and flow output for high-pressure heavy-load systems.

Product Summary

Hydraulic valves are the "control center" of a hydraulic system, responsible for regulating and controlling the direction, pressure, and flow of hydraulic oil, thereby ensuring that hydraulic actuators (such as cylinders and hydraulic motors) function as intended. Hydraulic valves are generally classified into three main categories based on their function: directional control valves, pressure control valves, and flow control valves. In addition, there are some combination valves and special-purpose valves.

Product Parameters

Product Application

This pump control valve is mainly suitable for construction machinery (large excavators, crawler cranes, concrete pump trucks), mining machinery (heavy roadheaders, mining dump trucks), metallurgical equipment (forging machinery) and port machinery (container cranes). Especially ideal for high-power hydrostatic transmission systems, it ensures efficient and stable equipment operation in high-pressure heavy-load environments with variable working conditions.

Product Features

1. Load-sensing control for high energy efficiency.

2. Pressure limiter function for system safety.

3. Good dynamic response and control stability.

4. Modular design for easy integration and service.

5. Suitable for high-pressure applications (up to 350 bar+).
