Installation
!
WARNING
Only qualied 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.
If the regulator vents uid 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 uid
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 Specications
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 uid. To avoid such injury
and damage, install the regulator in a
safe location.
The internal relief valve in the
67C Series regulators does not provide
full overpressure protection. The
internal relief valve is designed for
minor seat leakage only.
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 anged
bodies, use suitable line gaskets and approved
1. The pressure/temperature limits in this Installation Guide and any applicable standard or code limitation should not be exceeded.
2. Silicone (VMQ) is not compatible with hydrocarbon gas.
3. Do not use in high aromatic hydrocarbon service.
