installation

WarNiNg
Only qualified personnel should install
or service a regulator. regulators should
be installed, operated and maintained
in accordance with international and
applicable codes and regulations, and
emerson process Management regulator
technologies, inc. instructions.
1. The pressure/temperature limits in this Installation Guide and any applicable standard or code limitation should not be exceeded.
If the regulator vents fluid or a leak
develops in the system, it indicates that
service is required. Failure to take the
regulator out of service immediately may
create a hazardous condition.
personal injury, equipment damage or
leakage due to escaping fluid or bursting of
pressure-containing parts may result if this
regulator 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
regulator could result in personal injury
and property damage due to escaping fluid.
to avoid such injury and damage, install
the regulator in a safe location.
Clean out all pipelines before installation of the regulator
and check to be sure the regulator 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 regulator
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.
Note
it is important that the regulator be installed
so that the vent hole in the spring case
is unobstructed at all times. For outdoor
installations, the regulator 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 regulator beneath
eaves or downspouts and be sure it is above
the probable snow level.
overpressure protection
The recommended pressure limitations are stamped on
the regulator nameplate. Some type of overpressure
protection is needed if the actual inlet pressure
exceeds the maximum operating outlet pressure rating.
Overpressure protection should also be provided if the
regulator inlet pressure is greater than the safe working
pressure of the downstream equipment.
Regulator operation below the maximum pressure
limitations does not preclude the possibility of damage from
external sources or debris in the line. The regulator should
be inspected for damage after any overpressure condition.
