Specications
Specications for a given construction as it originally
comes from the factory are stamped on the main valve
and pilot nameplates. The main valve nameplate
is located on the main valve body. The pilot relief
pressure range appears on the pilot nameplate.
Principle of Operation
As long as inlet pressure remains below set pressure,
the pilot control spring keeps the pilot valve plug
closed (Figure 2). This pressure provides the loading
pressure to help the main valve spring keep the main
valve plug tightly shutoff.
An inlet pressure rise above the set pressure
overcomes the pilot control spring and opens the
pilot valve plug. Loading pressure bleeds out the pilot
exhaust faster than it can be replaced through the pilot
restriction. This permits inlet pressure to unbalance
the main valve plug and open the main valve. As inlet
pressure drops below set pressure, the pilot control
spring closes the pilot valve plug. Loading pressure
again builds up to close the main valve plug.
TYPE 63EG
Installation
WARNING
!
Personal injury, equipment damage or
leakage due to escaping gas (or liquid)
or bursting of pressure-containing
parts may result if the relief valve is
installed where its capabilities can be
exceeded or where conditions exceed
any ratings of the adjacent piping or
piping connections. To avoid this, install
a Type 63EG-98HM relief valve where:
• Service conditions are within unit
capabilities (including those given in
the Specications section)
• Service conditions are within applicable
codes, regulations or standards
Additionally, physical damage to the
relief valve could break the pilot off the
main valve, causing personal injury and
property damage due to escaping gas (or
liquid). To avoid such injury or damage,
install the unit in a safe location.

1. Call a qualied personnel when installing,
operating, and maintaining relief valves and
backpressure regulators. Before installing,
inspect the main valve, pilot and tubing for any
shipment damage or foreign material that may
have collected during crating and shipment. Make
certain the body interior is clean and the pipelines
are free of foreign material. Apply pipe compound
only to the external pipe threads with an NPT
body, or use suitable line gaskets and good bolting
practices with a anged body.
2. A Type 63EG-98HM may be installed in any
orientation, as long as ow through the valve
matches the direction of the arrow on the main
valve body.
WARNING
!
Type 63EG relief valves vent from the
main valve outlet and from the pilot
exhaust. In hazardous or ammable
gas service, personal injury, death or
property damage may occur due to re
or explosion or exposure of vented gas
(or liquid) that has accumulated. To
prevent such injury or damage, provide
piping or tubing to vent the gas (or
liquid) to a safe location. The exhaust
piping must be designed and installed to
guard against excessive ow restriction.
This piping must be protected against
condensation or anything else that could
clog it.
For safety during shutdown, vent valves
are required immediately upstream
and downstream of the main valve on a
backpressure or bypass installation.
3. If system operation is necessary during
maintenance or inspection, install isolating and
vent valves as needed.
4. A relief valve must be installed so that the pilot
exhausts properly and in a safe place. Make
sure to keep the pilot spring case vent open to
atmospheric pressure.
5. If the exhaust is to be piped to the main valve
outlet or remotely vented, install obstruction-free
tubing or piping with a minimum number of bends
into the 1/2 NPT pilot exhaust connection.

Type 63EG-98HM
6. If using pipe, apply a good grade of pipe
compound to the external pipe threads before
making the connection. Install tubing or piping into
the appropriate pilot connection.
7. Set pressure is dened as the pressure at which
the pilot starts to discharge. The set pressure
of a unit is adjusted by changing the control
spring compression on the pilot, by using the
adjusting screw.
8. Each pilot is factory set for the relief set pressure
specied on the order. If no setting is specied, set
pressure is factory set at the midrange of the pilot
control spring.
Startup and Adjustment
Key numbers are referenced in Figures 4, 5 and 6
unless otherwise indicated.
1. With proper installation and adjustment completed,
slowly open the upstream shutoff valve while using
gauges to monitor pressure. On backpressure or
bypass applications using an isolating bypass,
also open the downstream shutoff valve and close
the bypass valve.
Maintenance
Relief valve and backpressure regulator parts are
subject to normal wear and must be inspected and
replaced as necessary. The frequency of inspection
and replacement of parts depends upon the severity
of service conditions or the requirements of local, state
and federal regulations. Due to the care Emerson™
takes in meeting all manufacturing requirements
(heat treating, dimensional tolerances, etc.), use
only replacement parts manufactured or furnished by
Emerson. All O-rings, gaskets and seals should be
lightly lubricated with a good grade of general purpose
grease and installed gently rather than forced into
position. Be certain that the nameplates are updated
to accurately indicate any eld changes in equipment,
materials, service conditions or pressure settings.
WARNING
!
To avoid personal injury and
equipment damage, isolate the valve
from all pressure. Cautiously release
pressure from the valve before
attempting disassembly.
2. If set pressure adjustment is necessary,
monitor inlet pressure with a gauge during the
adjustment procedure.
Pilot Adjustment
Adjust the set pressure by loosening the pilot jam nut
(key 17) and turning the pilot adjusting screw (key 15)
clockwise to increase or counterclockwise to decrease
the set pressure. When the required set pressure is
maintained for several minutes, tighten the jam nut to
lock the adjusting screw in position.
Shutdown
Relief Installations
Slowly close the upstream shutoff valve. Release all
pressure from the main valve and pilot by opening the
upstream vent valve.
Backpressure or Bypass Installations
Slowly close the upstream shutoff valve while opening
the bypass valve if an isolating bypass is used. Then
close the downstream shutoff valve and open both
vent valves to release all pressure from the main valve
and pilot.

replacing individual parts in the trim package.
Key numbers for the Type 63EG main valve are
referenced in Figures 4 and 5.
Note
Access to the spring (key 9) or ange
O-ring (key 21) in step 1 can be gained
without removing the body ange (key 2).
1. Remove the pilot and pilot pipe nipple from the valve
body. Remove the body ange plug (key 27) and the
spring (key 9) and attached parts. Proceed to step 5 if
only performing maintenance on these parts.
2. Remove the cap screws (key 3) and pry the body
ange (key 2) loose from the valve body (key 1).
3. The valve body (key 1) can be used as a holding
xture by ipping the body ange over and anchor
it on the valve body as shown in Figure 3.
4. To gain access to the port seal (key 12), upper seal
(key 15) or valve plug parts, unscrew the seat ring

WARNING
!
To avoid personal injury, property
damage or equipment damage caused
by sudden release of pressure or
uncontrolled process uid, do not
attempt any maintenance or disassembly
without rst isolating the regulator
from system pressure and relieving all
internal pressure from the regulator.
Relief valves or regulators that have been
disassembled for repair must be tested
for proper operation before being returned
to service. Only parts manufactured by
Emerson™ should be used for repairing
Fisher® relief valves and regulators.
Note
When installing the trim package, align the
body ange and valve body side tappings.
7. Remove the upside-down body ange (key 2) if
it was anchored on the body. Lightly lubricate the
cage seating surfaces of the valve body web and
the body ange. Install the body ange on the
body (key 1) and secure it evenly with the cap
6
Due to normal wear and damage that may occur from
external sources, relief valve parts such as the O-rings,
gaskets, diaphragm, ori ce and valve plug should be
inspected periodically and replaced as necessary. The
frequency of inspection and replacement depends upon
the severity of service conditions or the requirements of
state and federal laws.
The following instructions explain the disassembly of
the Type MR98H relief or backpressure pilot. Lightly
apply a good quality lubricant when reassembling. Key
