hydraulic pressure limiting valve

Then are you interested to know a hydraulic limit valve? Sometimes called a "clapper valve," this valve is integral to machines that involve liquid, such as hydraulic systems. It makes sure that the pressure of the fluids within the system remains intact which is critical to making things function properly.

The primary function of hydraulic valve assemblys is to maintain the pressure of the hydraulic fluids within an acceptable range. These valves serve to ensure that the pressure does not fall outside this range. Pressure is (like) a balloon. You can blow up a balloon too much and it will pop. In a hydraulic system, excess pressure can cause serious damage as well. Too little pressure, on the other hand, and the machine may not run at all. And so when the pressure gets high enough, the valves will cut off the fluid flow or allow less fluid through. This is extremely important because if the pressure is too high or too low, it can damage the entire hydraulic system and create a situation where the hydraulic system is unsafe for operation.

Function and Design

The hydraulic valve block assemblys may come in many shapes or sizes, but they all share the same basic function. They are all responsive to variations in pressure. Within the valve itself is a spring that allows it to open and close according to the pressure in the system. When there is too high a pressure, it opens up forcing fluid to leak out which lowers the pressure. This is analogous to opening a soda can; the fizz and gas are released, inside pressure decreases. Heat from the combustion gases inside the cylinder causes the milk to expand, and when the pressure is too low, the valve closes, and the milk will not flow until the pressure inside the cylinder returns to the normal level. This valve keeps everything in a balance and safety.
