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.)
