Proportional Control: The Rexroth Electro-Hydraulic Proportional Directional Valve is known for its precise and proportional control of hydraulic fluid flow.
This enables operators to finely adjust the flow rate, providing exceptional control over hydraulic systems.
Directional Control: This valve is primarily used for controlling the direction of hydraulic fluid flow in a hydraulic circuit. It can seamlessly switch between different flow paths, making it ideal for applications where precise direction control is essential.
Electro-Hydraulic Operation: The valve is operated electronically, allowing for remote control and automation. It can be integrated into various industrial control systems for seamless operation.
High Precision: Rexroth valves are known for their high precision and reliability. They are built to operate with minimal hysteresis and ensure consistent performance over time, even in demanding environments.
Pressure Compensation: Many models of Rexroth proportional directional valves come equipped with pressure compensation features. This ensures that the valve maintains consistent flow rates regardless of changes in system pressure, enhancing system stability.
Various Sizes and Configurations: Rexroth offers a wide range of valve sizes and configurations to meet the specific needs of different applications.
This includes various flow capacities, mounting options, and voltage compatibility.
The primary function of the Rexroth Electro-Hydraulic Proportional Directional Valve is to control the flow and direction of hydraulic fluid in a system. It achieves this through precise adjustment of its internal components based on the electrical input it receives. Here's how it works:
Electrical Signal Input: The valve receives an electrical signal from a controller or automation system. This signal dictates the desired flow rate and direction.
Internal Components: Inside the valve, there are various components, including spools and solenoids, that respond to the electrical input. These components adjust the flow paths and openings within the valve to achieve the desired flow rate and direction.
Hydraulic Fluid Control: As the internal components move, they control the flow of hydraulic fluid through the valve. The fluid is directed to the appropriate hydraulic actuator or circuit based on the valve's configuration.
Feedback Mechanism: Many Rexroth proportional valves include feedback mechanisms that provide information on the valve's current position and performance. This data can be used for monitoring and control purposes.
