APPLICATION
The V4046C and V8046C Magnetic Valves provide on-off
control of gas flow in supply line.
V4046C, V8046C
Magnetic Valves
PRODUCT DATA
FEATURES
• Normally closed valves which open immediately when
energized.
• V4046C is for line voltage applications; V8046C is for
24 Vac applications.
• Provides on-off control of manufactured, Liquefied
Petroleum (LP), and natural gases with high sulfur
content.
• Used with pilot burners in industrial applications.
• All models close in one second (maximum) on power
failure.
• Heavily loaded spring plunger maintains valve seating
when the coil is de-energized, permitting the valve to
be mounted in any position.
• Valve may be pipe-mounted or mounted on bracket
support furnished by installer.
• Powerhead assembly can be rotated 360 angular
degrees.
• Solenoid coil is field-replaceable without removing the
valve body from the piping connection.

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.

Mixed 0.70 1.046
LP-Propane 1.53 1.546
LP-Butane 1.98 1.759
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.
