    how to determine valve cracking pressure area?

    Thanks for your feedback. Anyways with trial and error I can find the right spring but I wanted to understand the physics.

    how to determine valve cracking pressure area?

    @SPDL310 Yes that's exactly the issue. I tested each spring in load test machine. Also parts diameters measured in CMM to be sure of stack up problems. We also tried with reduced reduced red part diameter (i.e diameter reduced from 16mm to 13mm) and still the average diameter predicted the...

    how to determine valve cracking pressure area?

    Hello SPDL310, I uploaded new picture with gasket location to prevent leakage. In the test I recorded pipe wall tapping pressure gauge reading and hence static pressure. But do you think if the valve just cracks the velocity component of flow would have significant effect to consider total...

    how to determine valve cracking pressure area?

    Hello, Fluid flow pressure from the right side. The cylindrical valve attached to spring is supposed to open at a given pressure. In the picture attached what diameter to select to calculate the area to determine valve cracking pressure? 16mm or 19.8mm diameter? Theoretical there are 2...

    CFD on check valve (spring loaded)

    Thanks for the reply. I understand the valve design may be wrong (undamped control valve,.. But test result seems to be fine. Now I need to correlate test results with CFD.

    CFD on check valve (spring loaded)

    I have attached the circuit diagram. Check valve supposed to open >4bar and transfer the fuel to reservoir.http://files.engineering.com/getfile.aspx?folder=cb297465-af35-4879-bfa9-0066e6d7b572&file=circuit.PNG

    CFD on check valve (spring loaded)

    Yes I am trying to correlate test results(flow rate through check valve with line pressure) with CFD. Check valve is not standard valve available in market, we are trying to design the valve in house to fit it over an automotive fuel line component. Since its not standard its neither dart,disk...

    CFD on check valve (spring loaded)

    Check valve(which is spring loaded) mounted on an automotive component is supposed to open above some rated pressure. I have test data on check valve. Cracking pressure and flow rate through the check valve at different line pressure is observed. Different line pressure in test is simulated...
