GENERAL DESCRIPTION
The Hale Master Intake Valve is a NFPA
compliant large diameter intake valve that
is mounted in the pump suction tube
behind the pump operator panel. The valve
is a butterfly type valve that is available
either in manual or electric operation.
Safety features on the valve include an
integral relief valve and air bleeder valve
tap that vent to the atmosphere. The valve
assembly, less relief valve, is factory tested
to 600 PSI (41 Bar).
The Hale Master Intake Valve has a 6.4 inch
(163 mm) diameter bore with a butterfly
disc designed to provide minimum flow
restriction when the valve is open. The
unique design of the valve and butterfly
permits the valve to provide full water flow
up to 1500 GPM (5678 LPM) from draft
through a single 6 inch NST suction hose
when mounted on Hale pumps directly to
the main suction inlet under all standard
operating conditions. Due to the design of
the valve, there is minimum friction loss and
pressure drop across the valve.
When the valve is ordered as part of a Hale
Midship fire pump, the pump will pass UL
requirements up to 1500 GPM (5678 LPM)
from draft through a single 6 inch NST
suction hose with the valve in place. When
two valves are mounted to the fire pump
the pump can achieve UL flows up to 2000
GPM (7570 LPM) from draft through dual 6
inch NST suction hoses. The disc design also
permits easy maintenance and lubrication
of the valve disc. The disc is coated with
nitrile rubber material that is compatible
with most chemicals in use on the fire
ground.

MASTER INTAKE VALVE
The valve is available configured for
manual operation using a panel mounted
handwheel (MIV-M) or for electric
operation using a panel mounted switch
(MIV-E) for remote control operation.
Whether the manual or electric operated
valve is installed, lights on the panel placard
will illuminate to indicate if the valve is
open, closed or traversing from one position
to the other.
Also provided with the electric valve is a
manual override handwheel that permits
valve operation from outside the operator
panel. No special tools or parts removal is
required.
The valve gear actuator, manual or electric,
is designed to move the valve disc from the
fully closed to full open position using 10
turns of the handwheel. The electric
operated valve will cycle from the fully
closed to full open position in no less than 3
seconds therefore meeting NFPA
requirements. The matched gear set is
designed to permit operation with minimal
torque even at high flows and pressures.
The design of the gear actuator also
permits the valve to be placed into a
partially open position if it is necessary to
gate the intake flow.
Master Intake Valves are provided with a ¾
inch NPT suction hose priming port. This port
is located near the relief valve mounting
flange on the valve body. During pump
operations when an MIV is installed on the
main pump suction it may be desirable to
pre-prime the suction hose so fire fighting
capabilities are not lost when switching from
tank to draft operations.
Since the valve mounts behind the operator
panel, between the suction tube extension
and the suction tube, or in-line for front and
rear suction piping, there is less panel
clutter, obstruction of valve handles or
chance for damage to the valve body due
to overhang beyond the apparatus running
board.

Design of the relief valve permits the
discharge to be piped behind the operator
panel for increased operator and/or
bystander safety.

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
INSTALLATION
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
