How many types of Hydraulic valve are there ? Diffenciate between pressure relief and pressure reducing valve.

Question

Accepted Answer

There are various types of hydraulic valves, including pressure relief and pressure reducing valves.

Types of hydraulic valves include directional control valves, flow control valves, pressure control valves, and check valves.
Pressure relief valves are designed to limit the pressure within a hydraulic system by diverting excess fluid when the pressure reaches a certain level.
Pressure reducing valves, on the other hand, are used to maintain a constant pressure in a branch of a hydraulic circuit by diverting excess fluid back to the reservoir.
Examples of pressure relief valves include pilot-operated relief valves and direct-acting relief valves.
Examples of pressure reducing valves include pilot-operated reducing valves and direct-acting reducing valves.
