2. INTRODUCTION
This section provides an overview of the Hale Master Intake Valve (MIV) currently in production.
Additionally, the section provides information about How to Use This Manual and the Principles
Of Operation for the Master Intake Valve.
2.1. Overview
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 de-
signed 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 require-
ments 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.
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 illumi-
nate 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 part 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 cy-
cle 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 lo-
cated 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
firefighting 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.
The surface between the mounting flanges and Hale MIV valve body are sealed using reliable O-
ring seals in grooves machined in the Hale MIV body.

8
Design of the relief valve permits the discharge to be piped behind the operator panel for in-
creased operator and/or bystander safety.
2.2. Installation
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 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 mount-
ing flange of the MIV valve to permit remote mounting of the relief valve.

Figure 2. Component Part Identification (Manual 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 connec-
tions on the pump. The plate drawing, FSG-PL-01491, provides 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 appa-
ratus it will be necessary to install the relief valve discharge piping, air bleeder, suction hose
priming and drain valve (steps 2.2.3 through 2.2.9 in this section).
2.2.1 Mounting of Side Suction Valves
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 RE-
QUIRED. REFER TO MIV PARTS MANUAL, FSG-MNL-00218, FOR MOUNTING DIMEN-
SION 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 interfer-
ences for other operating equipment. The plate drawing, FSG-PL-01491, provides 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 suction tube extension and suction tube mating surfaces.
NOTE
USE ONLY 7/16-14 UNC X 4-¾ INCHES LONG GRADE 8 ZINC PLATED STEEL CAP
SCREWS, 7/16-14 UNC X 5-¼ INCHES LONG GRADE 8 ZINC PLATED STEEL STUDS AND
7/16- 14 UNC ZINC PLATED STEEL NUTS TO INSTALL THE MASTER INTAKE VALVE AND
SUCTION TUBE TO THE SUCTION TUBE EXTENSION.
Figure 3. STUD PLACEMENT FOR MIV INSTALLATION
NOTE
ALL CAP SCREWS, STUDS AND NUTS MUST BE LOCKED IN PLACE USING LOCTITE® #242
OR EQUAL THREAD SEALING COMPOUND.
NOTE
WHEN THE VALVE BODY IS INSTALLED MAKE SURE THE VALVE DISC IS NEXT TO THE
SUCTION TUBE EXTENSION. THE RELIEF VALVE, DRAIN VALVE, AIR BLEEDER VALVE AND
PRIMING VALVE MUST BE LOCATED ON THE INLET SIDE OF THE VALVE.

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
