Back pressure valve
Back pressure valve
(OP)
Hello,
I'm new here in this forum, and i find it amazing
I'm working on a bench test for testing check valves. I found some examples of this test where a back pressure is used at the outlet ( to the tank). I don't really understand what a back pressure valve does. Does it help maintain the pressure in a system? for example, if i connect my pump to it directly ( pump-> Back PV=> Tank), Would it help to rise the pressure in order for the circuit to function?
What are some of its characteristic that i need to design one.
Thank you for your time and help.

So from whay you said. it's a variable restriction changing flow to maintain to inlet pressure. Does the formula for flow in function of drop pressure apply to it? : ( Q=C.S.sqrt(drop pressure/density))) .
Thank you again
