Types of Rexroth Valves

Rexroth offers various types of valves, each designed with specific functionalities to cater to different system requirements. Understanding these types will help users to select the most appropriate valving solution for their applications.

1. Directional Valves

Directional valves manage the path of fluid flow within hydraulic circuits. They ensure that hydraulic oil is directed to the appropriate actuator at the right time, which is vital for systems requiring precise motion control. Rexroth's directional valves come in several configurations, including solenoid-operated and mechanically actuated versions, allowing for flexibility in installation and control methods.

2. Pressure Control Valves

Pressure control valves are essential for regulating pressure levels within hydraulic circuits. By maintaining preset pressure thresholds, these valves help protect hydraulic components from damage due to overpressure situations. Rexroth's pressure valves can adjust automatically to changing operating conditions, ensuring that system integrity is preserved while maximizing efficiency.

3. Flow Control Valves

Flow control valves are responsible for managing the flow rate of hydraulic fluids. By adjusting the flow, these valves optimize the speed of actuators and other components within the hydraulic system. Rexroth provides options like throttling valves, which allow for adjustable flow settings and enable fine control of movement within a system. This type of control is vital for applications such as mold clamping or lifting operations, where speed must be carefully managed.

4. Proportional Valves

Proportional valves enable smooth and precise control over flow rate and pressure, adjusting in accordance with electrical signals. This feature makes them highly suitable for applications demanding gradual motion changes and coordination across multiple actuators. Rexroth’s proportional valves enhance responsiveness and control, leading to improved operational accuracy and performance in industrial settings.
