Installation
!
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
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.

WARNING
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.
1
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.
