The unique design of the Hale Master Intake
Valve permits installation in the fire pump
suction tube behind the pump
compartment panel using a minimum of
space. The valve body is only 3-
3 /
8
inches
(86 mm) wide and various suction tube
options are available to fit most standard
pump compartment widths. (Refer to Hale
Bulletin 596, reprinted in section 9 of this
manual, for various suction tube options.)
The side mounted valve is installed behind
the pump compartment panel between
the suction tube and suction tube extension
(Figures 1 and 2). The design of the relief
valve mounting flange permits rotation of
the relief valve to redirect the outlet of the
relief valve as necessary as well as remote
mounting. There are 2-½ inch female NPT
threads machined into the relief valve
mounting flange of the MIV valve to permit
remote mounting of the relief valve.
Bottom mounted valves are installed to
bottom of the suction tube extension for use
with front and/or rear suctions (Figure 4).
The valve may also be installed in-line or it
may be used with large auxiliary pumps.
Optional Hale 6 inch NPT threaded flanges
are available for use in these installations.
Whether installing the valve during new
construction or installing the valve as a
retrofit proper planning and equipment
layout will ensure smooth installation. The
Hale MIV has been designed to mount onto
a Hale midship pump without interference
to other suction and discharge connections
on the pump. The current revision of Plates
814A, 815A, 841A and 842A, reprinted in
Section 9 of this manual, provide the overall
mounting dimensions for various
configurations of the Hale MIV.
When ordered as part of a new midship fire
pump the valve will be pre-installed on the
fire pump and tested at the factory per
NFPA requirements. When installing the
midship pump on the apparatus it will be
necessary to install the relief valve
discharge piping, air bleeder, suction hose
priming and drain valve (steps A through J
in this section).
The following steps shall be followed when
installing the valve on a midship fire pump.
Steps A and B can be eliminated if the Hale
MIV is installed on the midship pump at the
factory.
A. MOUNTING OF SIDE SUCTION
VALVES
(when not ordered as part of
midship pump)
NOTE: When installing the Hale MIV as a
retrofit it is highly recommended that the
standard suction extension be replaced
with the Hale P/N 178-0063-00-0 suction
extension. This is especially important on
apparatus with panel widths of 70, 72
and 74 inches to minimize panel
modification required. Refer to Section
9 of this manual for mounting dimension
drawings for assistance in planning
retrofit installations.
1. Determine the location of interferences
on the fire pump and the pump
operator panel. Proper planning and
layout of the pump operator panel will
reduce the potential interferences for
other operating equipment. The current
revision of Plate 814A and Plate 815A,
reprinted in Section 9 of this manual,
provide the overall mounting dimensions
for the Hale MIV.
2. Remove the cap screws that hold the
suction tube to the suction tube
extension. Remove the suction tube
from the pump. Be sure to remove all
old gasket or sealing material from the
