Common Hydraulic Schematic Symbols



Have you ever looked at a hydraulic schematic and wondered what all the symbols mean? Understanding common hydraulic schematic symbols can help you troubleshoot your system with accuracy and speed. From directional control valves to pressure relief valves, here’s an overview of some of the most common hydraulic schematic symbols and their meanings.

A hydraulic system is composed of several components that work together in order to move fluid to where it needs to go. The key to successful troubleshooting of hydraulic systems is devising a plan of attack, based on understanding the components involved and how they interact. In order to do this, you need to understand the symbols used to represent various components.

There are many symbols used in hydraulic schematics, and they can vary considerably from manufacturer to manufacturer. However, the most common symbols are standardized, so it pays to get familiar with them.

The first symbol you’ll come across is the directional control valve, which is usually represented by two parallel vertical lines, with an arrowhead pointing outwards. This is the component used to route the pressurized fluid to the various cylinders or motors.

Next up is the pressure relief valve, which is represented by a curved line with an arrowhead pointing outwards. This valve is designed to release excess pressure in order to protect the system components.

Then there’s the flow control valve, which is usually represented by a curved line with an arrowhead pointing inwards. This valve is used to regulate the flow of fluid in the system.

Finally, the check valve is represented by an arrowhead pointing towards the valve body. This is used to keep fluid from flowing back into the system.

These are some of the most common symbols used in hydraulic schematics. As you can see, understanding these symbols is essential if you want to effectively troubleshoot a hydraulic system. And while the symbols may vary slightly between manufacturers, the general principles remain the same. So, if you want to get the most out of your hydraulic system, you need to be familiar with these symbols.
