Every hydraulic system consists of a lot of different parts so that your system functions properly, they all need to be capable of working together. If one component is not quite right, it can affect the complete system’s performance and can hamper its proper functioning.
Hydraulic Pressure valves is a significant part of any hydraulic system, so you require to ensure that you select the right valve to meet your requirements. There are many of different valves available and it’s simple to become confused at the selection.
Definition of Hydraulic Pressure Valve and Its Function
A hydraulic Pressure valve properly controls the flow of a liquid medium, usually oil, through your hydraulic system. The direction of the oil flow is decided by the position of a spool. A hydraulic system can only work – as per requirements – by using valves. Thus, you should always search for the correct variety of hydraulic valve to fulfill your intended purpose. The needed size is decided by the maximum flow of the hydraulic system through the valve and the maximum system pressure.
Hydraulic Pressure valves are found in different sizes and according to various International Standards. Hydraulic valves are found in various mounting styles: e.g. mounting in pipelines, with the threaded connection as cartridge valves, flanged mounting. Hydraulic valves are classified into three main categories: directional control valves, pressure control valves, and flow control valves. All valves work on a various function in the hydraulic system for you, it’s always a good idea to take help of the professional advice.
In a hydraulic system, valves are used for oil control – executing the flow of hydraulic fluid throughout your system. There are many different types of hydraulic valves and are found including:
Different Types of Hydraulic Valves
Directional Control Valves
Directional control valves can regulate the start, stop, and change in direction of flow of a pressure medium (i.e. hydraulic oil). Hydraulic valves act like a poppet or spool valve.
Variety of Directional Control Valves
- Directional poppet valves
- Directional spool valves
- Check and non-return valves
- About directional control valves
- Pressure Control Valves
Pressure Control Valve
Every pressure control valve change at a predetermined pressure setting. This works either gradually with the variable throttle (control) or suddenly with a fixed throttle (switch).
Type of Pressure Control Valves
- Pressure valves, relief function
- Pressure valves, reducing function
- Pressure valves, a fixed throttle
- About pressure control valves
Proportional Control Valves
Proportional hydraulic valves are capable to handle the opening to flow proportionally rather than gradually, as is the time for most standard hydraulic valves.
Type of Proportional Control Valves
- Proportional directional control valves
- Proportional pressure control valves
- Proportional flow control valves
- About proportional control valves
Flow Control Valves
Flow control valves control the flow by decreasing or increasing the beginning at the throttling point. This helps to decide the speed of movement for the hydraulic actuators.
Type of Flow Control Valves
- Flow controls, pressure compensated valves
- Flow controls, a throttle valve
When trying to choose the right hydraulic valve type for your system, there are a few things you should consider:
- What function does the valve require to perform in your application?
- How will the valve be determined; manually (by levers or knobs), mechanically, hydraulically, pneumatically or electrically (by solenoids)?
- How will the valve be linked to your system; in-line with pipe or hose, mounted on or within a manifold?
Choosing the right hydraulic valve type needs an in-depth knowledge of your application and the function of the valve will be suggested to perform. You will also require to be cautious of certain factors including the valve’s pressure drop, frequency, adjustment range, leakage rate, and required fluid cleanliness from others.
The wrong valve selection will affect the functionality of your system and often causes problems in other areas of your system which cannot be affordable to resolve. Issues that can be the reason by poor valve choice includes over pressurization leading to component damage, poor performance, and efficiency, cavitation, malfunction, and machine damage.
