threads are started. Apply Loctite #242
or equal to the threads on the studs and
install the
7 /
16
-14 UNC grade 5 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.

nuts. Torque to 40 lb-ft (54 N-m) using a
cross pattern.
B. MOUNTING OF BOTTOM (FRONT/
REAR) SUCTION VALVES
(when not
ordered as part of midship pump)
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 machined 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 interference with
other operating equipment. Refer to the
current revision of Plate 841A and Plate
842A, reprinted in Section 9 of this
manual, 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 5 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.
