I am comparing the flow rates of 1.5'' and 2'' back pressure valves. I think 2'' valve should have much higher flow rate due to its bigger orifice size.
However, the flow rate of 1.5'' valve is actually a little bit higher. Both valves are installed on 2'' pipeline.
Any help?
Hello,
Does anyone know what the average pressure drop(or flow rate) of 1/4''(quarter inch) back pressure valve is?
I am having hard time finding this information for my valve.
Thank you
Hi,
I am testing a back pressure valve with water.
My valve came with 50psi factory setting which I assume that it requires 50psi to open the spring inside the valve and thus the maximum downstream pressure would not exceed 50psi.
However, no matter what the upstream pressure is downstream...
