How to Replace Hydraulic Pressure Valves with Understanding

How to Replace Hydraulic Pressure Valves with Understanding
  • Opening Intro -

    Hydraulic systems form important part of small and big machines operating as lifts and elevators, hydraulic jacks etc.

    Therefore, the responsibility on the hydraulic systems are too high for providing the strength and operability to the systems.


Under such conditions the valves in the system needs to be cared for, carefully checked, adjusted, and replaced as needed. Hence, a sound knowledge of the different types of hydraulic pressure valves is required for people in charge of hydraulic machines and systems.

Hydraulic Pressure Valves

Hydraulic pressure valves can be of several types. Valves may come with switches or controls. While switches can instantly shut the valve on or off, controls can instantly help in reducing or increasing the valve pressure. Besides the mode of control, valves can be distinctly separated among two common types, by mode of operation. They are pressure reducing valve, and pressure relief valve.

What Are Pressure Relief Valves

Pressure relief valves are used for relieving the pressure of a hydraulic system. The flow pressure to a tank can be partly or fully relieved using such valves. The relief valves come with the capacity to regulate higher flows. When you need to regulate or limit pressure in a hydraulic system, and that’s in between some preset levels, then the pressure relief valves come into use. Overall, these valves regulate and influence the amount of pressure which is given to the hydraulic system.

What Are Pressure Reducing Valves

These are valves which substantially reduce pressure inside a hydraulic subsystem. These valves can control regulated flows and are used when you want to control the output pressure which is transferred from a hydraulic system to its subsystem. Using these valves the primary or input pressure can be reduced or the secondary or output pressure can be maintained at a lower level. Keeping the system pressure same, one part of the circuit pressure can be lowered using these valves.

Fixed Throttle Pressure Valves

Two other valve types, which fall under the fixed throttle valve category, are the sequence and the unloading valves. The unloading valves are used for changing the flow direction to a pre-set system tank. The sequence valves changes flow to a secondary unit. The specialty of these valves is that they act as switches, and immediately swaps pressure settings without bringing the process through a gradual change of pressure.

Finding the Correct Valve Type

It’s highly essential that you invest on the correct valve type. To ensure that your valve type is correct, efficient, and from a reliable and reputed source, you can consult a hydraulic pressure system or unit specialist. When you are guided correctly about the right valve type during machine settings or old valve replacement etc, then you can invest in the right valve, and save your money, time, and effort from being wasted.

Basically, you would need to partner up with a good supplier for all your hydraulic pressure valves to ensure great quality, constant and immediate supply on demand, timely checks, and warranties on all supplies. This will make sure that your unit and production do not suffer hitches and problems from any faulty valve etc.

The Dependence on Valves

Any hydraulic system is totally dependent on valves. Without valves, pressure within the system cannot be controlled or reduced. Therefore, a system is of no use without the valves. To ensure totally functionality without any problem, the hydraulic system must get its valves checked periodically, and any replacement necessary must be done as soon as the problem is detected.
