To select a valve for YOUR application , use either Cv factor calculations, or this graph show- ing approximate pressure drop at various flows of #2 oil.
20000
Typically, pressure drop for fuel flows should not exceed 10% of inlet pressure.

For preheated #5 or #6 oil , multiply the required flow rate in gph by the factor in the table at right, then select a valve based upon that equivalent flow of #2 oil and the allowable pressure drop. For example: To size for 5 psig drop with a 3500 gph flow of #6 oil preheated to 140°F, the multiplier is 2. Equivalent flow of #2 oil is then 3500 × 2, or 7000 gph. Chart shows that a 5 psig drop requires a valve body with a Cv factor of at least 45.
