Hi Eld,

If you want I can design the hydraulic circuit for you on Matlab. If you have the details of the types of valves you are going to check and the range of the parameters of the valve, may be I can optimize the hydraulic system's design parameters.

Besides, as PWASS, has rightly mentioned, your relief valve will operate at bit higher pressure then the preset value.(Its called as cracking pressure).

 

Hello!
I have done some research and found that PRV are generally set while not in service. do you guys have any idea where i can find those prv for low pressure applications?
thank you

 

What pressure do you require and at what flow rate.

 

I m working between 1bar to 10 bar with a flow rate from 0 to 400 liters per hour.

 

I suggest a SUN hydraulics valve Part No. RPECLEN-FEV

If you're going to use it with water, I recommend using a stainless steel body option /AP

It has a pressure range of 1.7 - 28 Bar with a maximum flow rate of 6750 litres per hour.
