Oscillating pressure regulation system

[Projectitis]

Hi all,

I'm after a water system involving some sort of pressure valve (pressure regulator, relief valve etc - whichever gets the job done) where the inlet pressure is always OVER set-pressure, and the valve oscillates (opens and closes rapidly) in response. It is this oscillation that is desirable in my case :)

I am hoping for some sort of system that:
- Water flows through system
- Inlet water pressure builds up to be higher than set-pressure
- Valve opens (etc) that dumps inlet pressure
- In response to the lowered inlet pressure the valve closes again
- Process repeats ad infinitum at a fast rate to oscillate the valve

I am not concerned by the output. I am simply dumping the water.

Does a relief valve work like this by default?
If not, does anybody know of a valve, or a modification to a valve, that will produce this property?

Thanks in advance!
Peter

A relief valve will get the job done. It does work like that by default.

Don't expect great accuracy though. Also, what sort of volume are you looking to dump?

Thanks guys. The volume of water is not important - I am after the highest rate of oscillation I can get. I'm guessing I just need to tune the system so that the set pressure is much lower than the input pressure, but not too low to keep the valve open.

I would like to suggest looking into a pressure relief valve with a pilot operated design. This type of valve uses a pilot valve to sense the inlet pressure and control the opening and closing of the main valve. The pilot valve can be adjusted to release pressure at a set point, creating the desired oscillation effect. Additionally, this type of valve can be modified to have a faster response time, allowing for even faster oscillations. I would recommend consulting with a valve manufacturer or engineer to determine the best design for your specific needs.
