What is a key function of selector valves in a hydraulic system?

The primary role of selector valves in a hydraulic system is to control the flow of fluid. These valves are essential components that determine the specific pathway of hydraulic fluid through the system, allowing for the activation or deactivation of different hydraulic circuits. By directing fluid flow, selector valves enable the operation of various hydraulic actuators, such as cylinders and hydraulic motors, facilitating precise control over equipment movement and function.

In a typical application, a selector valve can be used to switch hydraulic fluid flow from one circuit to another, allowing operators to selectively engage different hydraulic functions as needed. This capability is crucial for achieving operational flexibility and efficiency in hydraulic systems, which are commonly used in a variety of applications including aviation, construction machinery, and industrial equipment.
