Types N563 and N863 Emergency Shutoff Valves
WARNING
!
Failure to follow these instructions or to
properly install and maintain this equipment
could result in an explosion and/or re
causing property damage and personal injury
or death.
Fisher® equipment must be installed,
operated and maintained in accordance
with federal, state and local codes and
Emerson Process Management Regulator
Technologies, Inc. instructions. The
installation must also comply with NFPA
No. 58, ANSI K61.1, and DOT standards.
Only personnel trained in the proper
procedures, codes, standards and
regulations of the applicable industries shall
install and service this equipment.
Introduction
Scope of the Manual
This instruction manual covers installation and maintenance
for the Types N563 and N863 Emergency Shutoff Valves
and Accessories.
Type N563 is UL® Listed for service in Propane or Anhydrous
Ammonia (NH3).
Type N863 is intended for all other compressed gas service.
Type N863 valves are serialized for the service specied
with the order. The user should check with the factory to
make sure the Type N863 valve materials are suitable for the
intended service and temperature conditions.
Reference to Type N563 also refers to the Type N863 unless
otherwise specied.
Tank Car Connection
The Type N563 has a 2 in. FNPT coupling allowing the user
the exibility to install the desired length of 2 in. NPT piping to
t the tank dome. Replacing a worn out pipe connection is now
easier as any desired length of schedule 80 pipe can be used.
Wrenching Hex – A wrenching hex is built into the
body, minimizing wear or damage when connecting or
disconnecting. A 1/4 in. FNPT opening in the hex portion can
be used to install a bleed valve.
Hardened Threads – The 2 in. FNPT threads on the nipple
portion are of hardened stainless steel to reduce wear from
repeated use.
Fuse Plug – Melting point 212°F / 100°C. Closes valve
when melted.
Installation
General
Figure 1. Type N563 Emergency Shutoff Valve
Description
Type N563 Snappy Joe™, Figure 1, Emergency Shutoff
Valves are intended for transferring product to or from
railroad tank cars, see Figure 2. The valves are used as
temporary connections between the tank car’s primary
shutoff valves and the hose or swivel type piping.

A typical installation schematic is shown in Figure 3, where
two valves are installed on the liquid lines and one on
the vapor line. To meet NFPA Pamphlet 58 requirements,
emergency shutoff valves must have a means of closure
at both the valve and a remote location. A quick-disconnect
coupling provides manual control at the valve. A suitable
two-way or three-way closure valve is required at a remote
location, preferably near the exit of the transfer site
.

Remote Closure
WARNING
!
A bleed orice is required on the outlet of
the pressure source regulator and before
the remote closure valve. This restricts the
pressure source ow to the system. Failure to
install a bleed orice may not allow the control
pressure to exhaust quickly enough to close
the emergency valves if the remote valve is
used or the control pressure line is broken.
The Remote Closure Valve should be simple in operation
and have enough capacity to quickly exhaust pressure
between the supply source and the Type N563. A bleed
orice, Fisher® part number 1D7470, should be placed in-line
after the pressure supply regulator to restrict ow. This
allows the remote closure valve to exhaust pressure, and
thus close the Type N563.
Pressure Supply Line
WARNING
!
The manual quick disconnect valve must
be used as the primary source to open and
close the Type N563. Do not bypass the
manual quick disconnect valve by hard
piping the supply line to the Type N563.
Failure to use the manual quick disconnect
will negate a portion of the NFPA 58
requirements for Emergency Shutoff Valves.
Regardless of how many remote closure valves are installed
in the system, the quick-disconnect coupling at the valve
is the primary means to open and close the Type N563.
Do not hard pipe the supply line to the Type N563 and then
use a remote closure valve as the primary activation valve.
The pressure supply line to the Type N563 can be run
along the transfer line back to a common pressure source
and remote closure valve. In this way actuating the remote
closure valve can close all emergency shutoff valves. It is
recommended that a remote closure valve be installed on
the working level of the unloading riser for the convenience
of personnel, however, it should not be used as the primary
means to open and close the Type N563.
Pressure Source
The pressure source should be clean, dry gas such as
air, nitrogen or CO
equivalent can be used to reduce the high pressures
encountered with these compressed gases.
Approximately 50 psig / 3.4 bar is needed to open the
N563 Series. (Less control pressure is required with low
product pressures.)

Roll-Away Protection
WARNING
!
It is not possible to insure that Type N563
valves will remain installed or intact in the
event of a tank car rollaway. Therefore,
additional protection for the riser piping and
valves are required.
Due to the various congurations of railcar domes, valves
and unloading risers, the Type N563 valve(s) may not remain
installed or intact during a rollaway.
It is recommended that a break-off pipe protect both the riser
hoses and the Type N563 valves. This break-off pipe should be
installed downstream of the protected tower back check valves
and ESV so that the break-off pipe threads pull out before the
hoses are pulled with more than 1500 lbs / 680 kg of force.
A schedule 80 pipe takes around 3000 ft-lbs / 4067 N•m of
torque to pull out at the threads.
Pneumatic Accessories
Use commercially available pneumatic controls, ttings and
tubing for the pressure control lines. Pneumatic 3-way valves
should quickly exhaust supply pressure to the Type N563
valves and at the same time shutoff inlet pressure.
Operation
1. Make sure the 2 in. NPT threads on the Type N563
and the Schedule 80 pipe nipple are clean and in good
condition. Use an appropriate pipe compound on the male
threads. Thread the nipple hand tight into the 2 in. FNPT
inlet end of the Type N563. Then wrench tighten the
nipple approximately two (2) additional turns. Check the
connection for leaks.
2. Tighten the 3 set screws (1/4-20 UNC x 0.25 in.) against
the pipe nipple. This helps secure the nipple to the
Type N563 so that the nipple does not unscrew at the
Type N563 instead of the tank car valve.
3. Slowly, but completely open the tank car’s primary shutoff
valves. Begin product transfer.
4. If the valve does close, stop the transfer and close the
nearest downstream valve and the tank car’s primary shut
off valve. Wait for the Type N563 valve to click open.
5. All valves should be completely open when pumping.
6. The operator must always be aware of where the remote
closure controls are located and know how to operate the
controls if an emergency requires valve closure.
7. When the transfer has been completed, close the primary
shutoff valves.
8. Bleed down the transfer hose or piping to avoid trapping
pressure between the primary shutoff valve and the
Type N563.

9. Close the Type N563 by taking off the quick-disconnect
coupling. (To remove the coupling simply pull back on the
release sleeve.)
10. Unscrew the transfer hose or piping from the Type N563,
and take the Type N563 off the primary shutoff valve.
Maintenance
WARNING
!
Only qualied service personnel should
attempt to repair these valves. Before starting
any type of repair, close off the upstream
valves and remove all pressure from both the
inlet and outlet of the Type N563 Emergency
Shutoff Valve.
At least once a month inspect and check the following things:
1. See that the remote closure valve(s) works freely.
Operate the valve to make certain it closes the
Type N563.
2. Make sure the quick-disconnect nipple is not blocked or
its exterior damaged or worn.
3. Check the quick-disconnect coupling for retention of
supply pressure when disconnected and check for leaks
when coupled.
4. Check for worn or damaged threads.
5. Check for joint leakage.
6. Retighten the 3 set screw securing the inlet piping to the
Type N563.

Replacing Internal Parts
With the exception of the quick-disconnect coupling and nipple
and the Acme coupling, the Type N563 is not designed for
eld repair. Due to the use of special re-resistant seals and
assembly techniques, repair should be made only by trained
personnel. If repair becomes necessary, contact your Fisher®
distributor or the factory for information and assistance.
Only parts manufactured by Fisher should be used for the repair
of Fisher Type N563 Valves. Be sure to give the complete type
number of the Type N563 when corresponding with the factory.
Type N563 Valves that have been disassembled for repair must
be tested for proper operation before being returned to service.
