How Hydraulic Valves Work?

What is a Hydraulic Valve?

It is a circuit element that determines the direction of the hydraulic fluid, changes its direction when desired, controls the pressure and flow rate of the fluid.

What are the functions of hydraulic valves?

It opens and closes the path of the fluid.
It changes the direction the fluid will travel.
It sends the fluid to the tank.
It adjusts the working speed of the receivers by controlling the flow rate of the fluid.
It protects the circuit elements against high pressures. It sends the increased pressure fluid to the tank.
By controlling the pressure of the fluid, it enables the circuit elements to work at certain pressures.
It controls the pressure, flow and direction of the fluid at certain time intervals.
Some valves can perform one or more of the tasks listed above.
PRESSURE CONTROL VALVES

These are the valves used in the pressure lines of hydraulic systems, which ensure that the pressure of the fluid is at the desired value.

Types According to the Places Used;

a) Pressure Relief valves
b) Pressure reducing valves
c) Pressure sequencing valves
d) Discharge valves
