WARNING
!
Failure to follow these instructions or
to properly assemble this equipment
could result in an explosion, re and/
or chemical contamination causing
property damage and personal injury
or death.

operated and maintained in
accordance with federal, state and
local codes and Emerson Process
Management Regulator Technologies,
Inc. instructions. The installation in most
states must also comply with NFPA
No. 58, and ANSI Standard K61.1.
Only personnel trained in the proper
procedures, codes, standards and
regulations of the applicable industrial
service should assemble, install and
service this equipment.
The use of non-Fisher actuators will void
internal valve warranty and may result in
leakage of the gland packing caused by
premature wear. In addition to premature
wear, the use of non-Fisher actuators
may result in lower than expected ow
rates and possible leakage across the
valve seats.

Introduction
Scope of the Manual
This instruction manual provides instruction for
the installation, operation and maintenance of
Type C477GFV foot valves for ISO containers.
www.fisherregulators.com
Product Description
Fisher Type C477GFV modular foot valves are
installed at the bottom of ISO containers to ensure
that the loading and unloading of uid products are
controlled and to prevent leakage from the container
connection during transportation. Type C477GFV
modular foot valves are available in 2 and 3 in. NPT
stainless steel bodies.

Figure 3. Type C477GFV Modular Foot Valve Assembly Drawing
Type C477GFV modular foot valve as assembled in
the factory is composed of a complete set of valves
and accessories listed in Specications table. This
includes an internal valve (Type C477G Jet Bleed
Internal™ Valve) and a hand ball valve (Type N610L
Ball Valve) connected together by a pipe nipple and a
sealing brass cap which is connected to the end of the
assembly through a stainless steel adaptor.
Installation
WARNING
!
To avoid any personal injury, make sure
to close the internal valve and ball valve
before removing the brass cap (key 5)
after any leak test procedure or when the
foot valve is already installed.
CAUTION
Do not install the modular foot valve
assembly with such extreme torque
that the ISO container coupling can cut
threads into the valve. This could cause
valve distortion and affect the internal
working parts.
Do not use excessive force to remove
the brass cap (key 5) during installation,
leak testing or while in service. If the cap
is difcult to remove, counterhold the
adaptor (key 4) while removing the cap
to prevent loosening of any joints and to
avoid leakage.
Before installing the foot valve into an ISO container,
add additional support for the valve assembly if
needed. The additional support may be necessary to
ensure the foot valve is adequately protected and a
secure connection to the container is maintained.
Apply thread sealant appropriate for the installation’s
service and temperature conditions to the internal
valve’s (key 1) male NPT threads, and if required, to
ISO container’s female threads. Install the modular
foot valve assembly into the ISO container hand
tight, then properly tighten using a wrench on the
internal valve wrench ats, but do not over torque.
After installation, test the whole unit to ensure leak
free operation.
Ensure that the handles of the ball valve and internal
valve are oriented so that they don’t interfere with each
other. The ball valve handle should not be obstructed
by the internal valve handle’s operating path. See
Figure 2 for proper positions of handles to ensure the
closing path of the ball valve handle will be directed
away from the internal valve handle.

Operation
WARNING
!
The internal valve must be closed except
during product transfer. A line break
downstream of a pump may not actuate
the excess ow valve. If any break
occurs in the system or if the excess
ow valve closes, the system must be
shut down immediately.
1. Before a uid transfer, verify that the Type N610L
ball valve (key 3, Figure 3) handle and the internal
valve is closed. See ball valve operation below.
2. Remove the Type M441 end cap (key 5) slowly
and install the connecting hose.
3. Open the internal valve (key 1) partially. Once
pressure equalization is reached, the internal
valve poppet will fully open (refer to Type C477G
Instruction Manual).
4. Open the ball valve handle (key 3) to begin the
uid transfer.
5. Once the tank uid transfer is completed, close the
internal valve (key 1) then perform any necessary
downstream bleeding.
6. Remove the connecting hose, close the ball valve
(key 3) and re-install the end cap (key 5).
Ball Valve Operation (See Figure 2)
1. To open valve from the closed position, rotate the
handle a quarter turn counter clockwise until it is
oriented parallel to valve body.
2. To close valve from the open position, rotate the
handle a quarter turn clockwise until it is oriented
perpendicular to valve body.
Maintenance
WARNING
!
Do not use these internal valves if they
leak, fail to work properly, have been
damaged or have missing parts. Prompt
repairs should be made by a properly
trained service person. Continued use
without repair can create a hazardous or
injurious situation.
A simple preventative maintenance program for
the valve and its controls will eliminate a lot of
potential problems
Fisher® recommends these steps be conducted once a
month. Also refer to applicable regulations
for further specications. For United States, refer
to the Department of Transportation (DOT) CFR 49
Sections 180.416 and 180 Appendix A and B.
1. Review and complete the recommended
maintenance procedures in the Type C477G
Internal Valve Instruction Manual.
2. Inspect the ball valve operating lever to see that
it operates freely and that there is no leakage
around the retainer nut. If there is sticking or
leakage, replace the ball valve (key 3). See below
for detailed instructions.
3. Replace the elastomeric at seal on adaptor
(key 4) as part of preventative maintenance or if it
is observed to be damaged or worn.
Replacing Ball Valves
In replacing ball valves, follow the instructions below
and reference Figure 3:
1. Conrm internal valve (key 1) is closed.
2. While rmly holding internal valve (key 1) in place,
turn ball valve (key 3) and remove it (with the rest
of foot valve).
3. Remove adaptor (key 4) from ball valve (key 3).
Clean exposed threads.
4. Remove pipe nipple (key 2) from ball valve (key 3)
(if still attached). Clean exposed threads.
5. Apply thread sealant on new ball valve (key 3) and
adaptor mating threads. Securely assemble them
together. Do not over tighten.
6. Apply thread sealant on pipe nipple (key 2)
threads, on mating ball valve (key 3) and on
internal valve (key 1) threads.
7. Loosely insert pipe nipple (key 2) between internal
valve (key 1) and ball valve (key 3).
8. While rmly holding internal valve (key 1) in place,
grab ball valve (key 3) and securely assemble it
with pipe nipple (key 2) and internal valve,
making sure valve handles will not interfere. Do
not over tighten.
9. Allow for thread sealant curing time as needed.
10. Verify there are no leaks.
