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
67DFSR Series regulators do 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 piping and bolting practices.
Install the regulator in any position desired, unless
otherwise specied, but be sure ow through the body
is in the direction indicated by the arrow on the body.

67D Series
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
trafc 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.
Startup
The regulator 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 shut-off valves.
Adjustment
To change the outlet pressure, remove the closing
cap or loosen the locknut and turn the adjusting
screw clockwise to increase outlet pressure or
counterclockwise to decrease pressure. Monitor
the outlet pressure with a test gauge during the
adjustment. Replace the 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 regulator from all pressure before
attempting disassembly.
