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.
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.
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 flanged bodies, use
suitable line gaskets and approved piping and bolting
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.
