Oversize Relief Valve

[Dacosta]

I have an oil pot that needs a relief valve. My calculations say I need a relief valve that has at least a 2.5 lb air/min flow. The smallest relief valve I can find is a 11.11 lb air/min but its 10 weeks out! I have a 40 lbs air/min relief valve in stock. The location has no diffusion tank, nor does it have a common relief header. This relief valve will have a separate line that vents to atmosphere.

Is there a problem if I install this oversize relief valve on this oil pot?

You can do it if your pipe away is sized correctly. Did you check with Cyrus Shank? The 800 has 9.34 lbs/min of air @ 250
