See body sizes, Fig. 2. 55 cfh (1.56 cmh) is for large body valve with 1/4-18 NPT threads; 67 cfh (1.90 cmh) is for large body
valve with 3/8-18 NPT threads.

Natural gas, 1000 btu/cu ft measured at one inch pressure drop, 0.64 specific gravity. See Gas Capacity Conversion Factors.

Gas Valve Sizing
1. Check the burner nameplate for:
a. the type of gas used, and
b. the gas flow capacity. The capacity will be listed in
British thermal units per hour (Btuh)) or in cubic feet
per hour (cfh).
2. Contact the local gas utility for information regarding:
a. the specific gravity (sp gr) and
b. the Btu per cubic foot (Btucf) for the type of gas
used.
3. Find the capacity in cfh. If the capacity is listed in Btu,
convert to cfh using the following formula:
Capacity in cfh = Btuh (burner nameplate)
Btu/cu ft (gas utility)
4. For gases with specific gravity other than 0.64, multiply
the burner cfh using the proper conversion factor in
Table 4.
Table 4. Gas Conversion Factors.
5. Use the corrected burner capacity in cfh when
determining the gas valve size in Fig. 1.
6. Determine the maximum pressure drop to be taken
across the valve. If pressure drop is not in pounds per
square inch (psi), multiply the value in known pressure
units by the conversion factor.
7. Plot the capacity (cfh) vs. pressure drop (psi) in Fig. 1 to
find the proper valve size.
NOTE: Use the corrected cfh for gas other than 0.64 sp gr.
