The 446 Series valves are designed to shut off liquid ow in the event of a re. A fusible link is used to hold
open a spring actuated lever. When the fusible link melts the spring actuated lever is released to close the valve.
NOTE: Valve is rated to an operating pressure of 50 psi within the temperature range of -20°F to 125°F.
Failure to follow any or all of the warnings and instructions in this document could result in a hazardous
liquid spill, which could result in property damage, environmental contamination, re, explosion, serious
injury or death.
Le fait de ne pas se conformer à l’un ou l’autre des avertissements ou à l’une ou l’autre des directives
apparaissant dans ce document pourrait donner lieu à des déversements de liquides dangereux, lesquels
pourraient engendrer des dommages matériels, des risques de contamination environnementale,
d’incendie ou d’explosion, des blessures graves ou la mort.
Installation
WARNINGS
• Fire Hazard – Death or serious injury could result from spilled liquids.
• Any modication of this unit beyond what is outlined in this instruction will void product warranty.
• Install in accordance with all applicable local, state, and federal laws.
• For your safety, it is important to follow local, state, federal and/or OSHA rules that apply to working inside,
above, or around the storage tank and piping area. Use all personal protective equipment required for working
in the specic environment.
• Maximum pressure is 50 psi.
• Piping could be under pressure. Liquid and vapors may be expelled from the piping, valves or ttings while
performing installation. Liquids and vapors could catch re or cause an explosion. Avoid sparks, open ame, or
hot tools when working on valves.
AVERTISSEMENTS
• Risque d’incendie – Un déversement de liquide pourrait entraîner des blessures graves ou la mort.
• Toutes les modications apportées à cette unité autres que celles indiquées dans ces directives engendreront
l’annulation de la garantie du produit.
• Lors de l’installation, conformez-vous à toutes les lois locales, d’État et fédérales applicables.
• Pour assurer votre sécurité, il est important de vous conformer à la réglementation locale, d’État, fédérale
ou OSHA régissant les travaux à l’intérieur, au-dessus ou autour du réservoir de stockage et de la zone de
canalisation. Utilisez tout l’équipement de protection individuelle exigé pour travailler dans l’environnement
spécique.
• La pression maximale est de 50 psi.
• Les canalisations pourraient être sous pression. Des liquides et des vapeurs pourraient être expulsés des
canalisations, des soupapes ou des raccords durant l’installation. Les liquides et les vapeurs pourraient
s’enammer ou engendrer une explosion. Évitez les étincelles, les ammes nues ou les outils chauds lors de
travaux menés avec les soupapes.

Steps
1. Inspect valve for shipping damage. Do not use if valve is damaged. Call Morrison Bros. Co. for assistance.
2. Inspect valve openings for foreign matter such as packaging material. Remove any that is found.
3. Prior to mounting the valve in the piping, manually open and close the valve several times making certain
that the handle travel is free from sticking or binding. Next open the valve handle to the fully open position and
release the handle. Keep all body parts out of handle travel path. The valve should snap shut. If any binding
or sticking is found, or the valve will not snap shut, do not use the valve. Call Morrison Bros. Co. for assistance.
4. Verify the intended direction of liquid ow. The 446 Series valves can be mounted in the horizontal plane or
the vertical plane. If installing in the horizontal plane, the valve cap MUST be pointing straight up. If installed
in the vertical plane the liquid MUST be owing downward through the valve.
5. The valve is marked with a ow direction arrow. Make certain to install the valve such that the ow of liquid
through the valve corresponds to the ow arrow indicator.
6. Install valve to piping. Apply a non-hardening, fuel resistant thread sealant to the male threads of the pipe.
When threading valve onto the piping, and piping into the valve, make certain to wrench on the valve hex
closest to the end you are threading.
7. Improper wrenching can cause separation of valve components resulting in leakage.
8. Before lling the tank, manually open and close the valve several times making certain that the valve handle
is free from interference. Also make certain that there is no sticking or binding in the travel of the handle. If any
sticking or binding is found do not use the valve. Call Morrison Bros. Co. for assistance.
9. Manually open the valve to full open position and release the handle. Keep all body parts out of handle
travel path. The valve should snap shut. If this does not occur, do not use the valve. Call Morrison Bros. Co.
for assistance.
10. The tank may now be lled. During lling, inspect the piping and valve for leaks. Repair as is necessary.
11. Do not paint valve unless necessary. If painting, extreme caution must be exercised to make sure that the
paint does not inhibit proper valve operation.
Failure to follow any or all of the warnings and instructions in this document could result in a hazardous
liquid spill, which could result in property damage, environmental contamination, re, explosion, serious
injury or death.
Le fait de ne pas se conformer à l’un ou l’autre des avertissements ou à l’une ou l’autre des directives
apparaissant dans ce document pourrait donner lieu à des déversements de liquides dangereux, lesquels
pourraient engendrer des dommages matériels, des risques de contamination environnementale,
d’incendie ou d’explosion, des blessures graves ou la mort.
Maintenance
Annual inspection, at a minimum, is required to verify proper valve function.
WARNINGS
• Fire Hazard – Death or serious injury could result from spilled liquids.
• Follow your employer’s instructions for inspecting unit.
• You must be trained to maintain this valve. Stop now if you have not been trained.
• For your safety, it is important to follow local, state, federal and/or OSHA rules that apply to working inside,
above, or around the storage tank and piping area. Use all personal protective equipment required for working
in the specic environment.
• Valves and piping could be under pressure. Liquids and vapors could be expelled from tank piping, valves or
ttings while performing maintenance. Liquids and vapors could catch re or cause an explosion. Avoid sparks,
open ame, or hot tools when working on valves.

Steps
1. Release fuse link from stud on body while holding the valve handle.
2. Manually close and open the valve several times. Make certain there is no sticking or binding during this
process. If any sticking or binding is found, call Morrison Bros. Co. for assistance.
3. Manually move the valve handle to the full open position and release the handle. Keep all body parts out of
handle travel path. The valve should snap shut. If this does not happen, repeat step 2 and try again. If the valve
still does not snap shut, call Morrison Bros. Co. for assistance.
4. Inspect the fusible link for signs of wear, damage, or corrosion. If any is found replace the parts with original
replacements from Morrison Bros. Co.
5. Inspect the valve body for damage, leaks or excessive corrosion. If any are found replace the valve.
6. Manually open the valve and secure the fuselink.
7. Do not paint valve unless necessary. If painting, extreme caution must be exercised to make sure that the
paint does not inhibit proper valve operation.
