Installation
!
WARNING
Only qualified personnel shall install
or service a relief valve. Relief
valves should be installed, operated
and maintained in accordance with
international and applicable codes and
regulations and Emerson Process
Management Regulator Technologies,
Inc. instructions.
If using a relief valve on a hazardous
or flammable fluid service, personal
injury and property damage could
occur due to fire or explosion
of vented fluid that may have
accumulated. To prevent such injury
or damage, provide piping or tubing to
vent the fluid to a safe, well-ventilated
area or containment vessel. Also, when
venting a hazardous fluid, the piping
or tubing should be located far enough
away from any buildings or windows
so to not create a further hazard and
the vent opening should be protected
against anything that could clog it.
Personal injury, equipment damage
or leakage due to escaping fluid
or bursting of pressure-containing
parts may result if this relief valve is
overpressured or is installed where
service conditions could exceed the
limits given in the Specifications
section or where conditions exceed
any ratings of the adjacent piping or
piping connections.
To avoid such injury or damage,
provide pressure-relieving or
pressure-limiting devices (as required
by the appropriate code, regulation
or standard) to prevent service
conditions from exceeding limits.
Additionally, physical damage to the
relief valve could result in personal
injury and property damage due to
escaping fluid. To avoid such injury
and damage, install the relief valve in a
safe location.
Clean out all pipelines before installation of the
relief valve and check to be sure the relief valve
has not been damaged or has collected foreign
material during shipping. For NPT bodies, apply pipe
compound to the external pipe threads. For flanged
bodies, use suitable line gaskets and approved
piping and bolting practices. Install the relief valve
in any position desired, unless otherwise specified,
but be sure flow through the body is in the direction
indicated by the arrow on the body.
1. The pressure/temperature limits in this Installation Guide and any applicable standard or code limitation should not be exceeded.
2. Relief pressure plus maximum allowable build-up over setting.

Installation Guide
D102680X014
English – July 2017

Note
It is important that the relief valve be
installed so that the vent hole in the
spring case is unobstructed at all times.
For outdoor installations, the relief valve
should be located away from vehicular
traffic and positioned so that water, ice
and other foreign materials cannot enter
the spring case through the vent. Avoid
placing the relief valve beneath eaves or
downspouts and be sure it is above the
probable snow level.
Note
Do not adjust main valve spring.
Overpressure Protection
Maximum inlet pressures depend upon body materials
and temperatures. Refer to the nameplate for the
maximum inlet pressure of the valve. The valve should
be inspected for damage after any overpressure
condition. Fisher™ relief valves are NOT ASME
safety relief valves.
Startup
The relief valve is factory set at approximately the
midpoint of the spring range or the pressure requested,
so an initial adjustment may be required to give the
desired results. With proper installation completed
and relief valves properly adjusted, slowly open the
upstream and downstream shutoff valves (if applicable).
Adjustment
To change the set pressure, remove closing cap
or loosen the locknut and turn the adjusting screw
clockwise to increase set pressure or counterclockwise
to decrease pressure. Monitor the set pressure with a
test gauge during the adjustment. Replace closing cap
or tighten the locknut to maintain the desired setting.
Taking Out of Service (Shutdown)
!
WARNING
To avoid personal injury resulting from
sudden release of pressure, isolate the
relief valve from all pressure before
attempting disassembly.
If pressure is introduced first to
the main valve before the pilot, the
main valve may go wide-open and
subject the downstream system to full
inlet pressure.
