Types of hydraulic valves and their functions

The hydraulic valves direct the liquid medium with respect to the hydraulic system. They come in variable sizes, as per the International Standards. In a particular hydraulic system, the hydraulic valves perform different functions and allow the system to operate well. The three basic models of hydraulic valves are pressure control, flow control, and directional control hydraulic valves. They all have a specific function in the hydraulic system and their names are self-explanatory. These three types of valves are smooth in operation and performance and work as a whole system.

Pressure control Hydraulic valves

These valves tend to change and regulate the pressure within the tubes of the hydraulic system. They maintain the preset pressure settings, manually given by the operator. The pressure change generally comes suddenly and there are various reasons responsible for the pressure variations.

Sometimes the pressure can be too high and these hydraulic valves help in relieving the necessary pressure by preventing from leakages and bursting of the pipes. The hydraulic valves successfully release the excess pressure and maintain the internal pressure. Sometimes the internal pressure is too low for operations and with the help of pressure valves, one can also increase the working pressure for better operations.
