Hydraulic valves in a system are sometimes known as the hydraulic component. These components are divided into many different categories and the main categories are further divided into subsystems. They are described below.
1. Directional Control Valves: These appropriate hydraulic valve help in controlling the direction of the flow. The types of valves in this category are: Check valves, Spool valve, Poppet valve.
2. Pressure Control Valve: They have a set pressure value that helps in the performance of the valve. They can provide the system with the control of pressure across the system and help in switching the pressure value in the system.
