Individual drain lines should be used on each check valve. The waterway
check valves must be rated for 500 PSIG (34.5 BAR) test pressure.
Hale 3” (76mm) “115” flange-type check valves (p/n: 038-1570-00-0) can be
used for most installations on pumps with “115” style flanges. The Hale
“115” flange type check valve has a 4-3/8” (111mm) bolt circle that fits stan-
dard Hale “115” flanges, as well as 4-3/8” (111mm) bolt circle discharge
flanges on other pumps. These check valves are rated for pressures up to
500 PSI (34 BAR) and flows up to 750 GPM (2,839 LPM). Use 2-1/2” or 3”
(64mm or 76mm) NPT threaded “115” flanges for mounting these check
valves in piping runs.
Where higher flows and larger diameter piping is required, Hale offers a 4”
(102mm) “2433” flange-type check valve (p/n: 038-1570-04-0). The “2433”
valve has an 8 bolt, 5-3/4” (146mm) bolt circle and fits pump discharge
openings and flanges having this configuration. The “2433” check valve has
a pressure rating of 500 PSI (34 BAR) and a flow rating of 1,250 GPM
(4,731 LPM). The Hale “2433” style flange (p/n: 115-0040-00-0) has an 8
bolt, 5-3/4” (146mm) bolt circle and 4” (102mm) NPT threads for in-line
mounting of the 4” (102mm) check valve.
Flushing Water Hose
Flushing water connections for the Hale ADT, MDT II or MST require using
1/2” (13mm) inside diameter tubing and appropriate fittings. The tubing and
fittings used must be capable of withstanding the maximum fire pump dis-
charge pressure (500 PSI [34 BAR] minimum) and must be compatible with
foam concentrates being used in the system.
When the ADT, MDT II or MST is installed, a check valve is used integral to
the flushing water line connection. This provides protection against water
system contamination with foam concentrate.
Note: The installer/builder should provide an additional check valve and shut-off
valve where the flushing water hose connects to the water pump.
Hale recommends the use of one of the above selector options to provide
foam system flushing capabilities. However, if the Hale FoamLogix system
is ordered with the “no tank” option the system installer must maintain NFPA
compliance. To be NFPA compliant, when flushing is required, the system
installer must provide proper
