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
Specications 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.
1. The pressure/temperature limits in this installation guide or any applicable standard limitation should not be exceeded.
2. For stability or overpressure protection, a pressure reducing regulator may be installed upstream of the pilot according to the Installation section.
3. Type 61H pilot used with a 99 Series regulator can handle a maximum inlet pressure of 27.6 bar / 400 psig.

WARNING
61 Series
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 specied, but be sure ow 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
trac 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 shuto 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.
