3. Apply a coating of Loctite® #243 or equal thread locking compound and install the 7/16-
14 UNC X 5-¼ inch long studs into two holes of the suction tube extension. Torque the
studs to 40 lb-ft (54 N-m). These studs are used to support the valve and suction tube
during installation. The studs are installed in the holes located at the 1 o’clock and 7
o’clock position on the suction tube extension. (See figure 3)
4. Make sure the O-ring seals are seated in the grooves on the valve body and coat all seal-
ing surfaces with a light coat of general-purpose grease.
5. Install the valve body and suction tube over the studs taking care not to damage the
threads on the studs. Apply a coat of Loctite® #243 or equal thread locking compound
and insert the (8) 7/16 -14 UNC x 4-¾ inch long grade 8 zinc plated steel cap screws
through the holes in the suction tube and thread into the holes on the suction tube exten-
sion. DO NOT tighten the cap screws until all threads are started. Apply Loctite® #243 or
equal to the threads on the studs and install the 7/16-14 UNC grade 8 zinc plated steel
nuts on the studs.
NOTE
WHEN INSTALLING THE HALE MASTER INTAKE VALVE 8 SUCTION TUBE CAP SCREWS, 2
STUDS AND 2 NUTS WILL BE USED. CAP SCREWS CANNOT BE INSERTED WHERE THE
GEARBOX ADAPTER (9 O’CLOCK POSITION) AND TRUNNION (3 O’CLOCK POSITION) ARE
LOCATED. SEE FIGURE 3.
6. Tighten all suction tube cap screws and nuts. Torque to 40 lb-ft (54 N-m) using a cross
pattern.
2.2.2 Mounting of Bottom (Front/Rear) Suction Valves
The Hale MIV-E can be mounted to the bottom opening of Hale suction tube extension P/N 178-
0063-01-0 for use in front and/or rear suctions. The bottom opening of this extension is ma-
chined to accept Hale 2417 series 12 bolt flanges. A special 6 inch NPT threaded flange Hale
P/N 115- 0441-00-0 must be used when mounting the Hale MIV-E on the bottom opening of this
suction tube extension. Ordinary flanges will not provide proper clearance for the valve disc.
When installing the Hale MIV-E in front or rear suction piping do the following:
1. Determine the location of interference on the fire pump and the pump operator panel.
Proper planning and layout of the pump operator panel will reduce the potential interfer-
ence with other operating equipment. Refer to the current revision of Plate FSG-PL-
01491, for the overall mounting dimensions for the Hale MIV.
NOTE
USE ONLY 7/16-14 UNC X 5-¾ INCH LONG GRADE 5 ZINC PLATED STEEL CAP SCREWS,
7/16-14 UNC X 6-¼ INCH LONG GRADE 8 ZINC PLATED STEEL STUDS AND 7/16- 14
UNC ZINC PLATED STEEL NUTS TO INSTALL THE MASTER INTAKE VALVE AND FLANGE TO
THE SUCTION TUBE EXTENSION.
NOTE
ALL CAP SCREWS, STUDS AND NUTS MUST BE LOCKED IN PLACE USING LOCTITE® #242
OR EQUAL THREAD SEALING COMPOUND.
