Hydraulic Pump Control Valve

Product Introduction

The control valve for A11VO series hydraulic pumps is an integrated module by Rexroth for this swashplate piston pump line, including load-sensing and electro-hydraulic proportional types. It enables stepless displacement adjustment and dual pressure/flow control, with a 350bar rating, suitable for open circuits, serving as the core regulation unit for construction and industrial hydraulic systems.

Product Summary

Hydraulic pump control valves are critical components in fluid power systems, responsible for precisely regulating the flow, pressure, and direction of hydraulic fluid. They act as the essential link between the hydraulic pump and the actuators (cylinders or motors), ensuring optimal system performance, efficiency, and safety.

Available in various types—such as pressure control, flow control, and directional control valves—they cater to diverse industrial applications. Their primary functions include managing system pressure to prevent overload, controlling actuator speed, and enabling complex motion sequences with accuracy.

Product Parameters

Product Application

 A11VO series hydraulic pump control valves apply to multi-actuator circuits of mining roadheaders and concrete pumps, precise regulation of metallurgical continuous casters and wind turbine pitch systems, and closed-loop pressure/flow control of high-precision injection molding machines and test benches, ensuring system stability and energy efficiency under heavy-load, multi-action conditions.

Product Features

A11VO pump control valve core features are as follows:

Integrating load-sensing and proportional control, it enables load-independent speed regulation;

response ≤0.15s with excellent dynamic performance;

vibration and wear-resistant for harsh conditions;

pump-integrated design simplifies installation.
