Installation
!
Only qualied 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
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.
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.
1. The pressure/temperature limits in this installation guide or any applicable standard limitation should not be exceeded.

Note: Maximum inlet pressure not exceeded 103 bar / 1500 psig.
1. Inlet pressure must not exceed the sum of the actual outlet pressure setting and the maximum allowable pressure drop. For example, with an outlet pressure setting of 13.8 bar / 200 psig
9.5 mm / 3/8 in. orice with a maximum allowable pressure drop of 500 psid / 34.5 bar d, the maximum inlet pressure is 48.3 bar / 700 psig.
2. Nitrile (NBR) valve disks are normally furnished for pressure drops to 13.8 bar / 200 psi, differential. For better erosion resistance, Nylon (PA) valve disks are normally furnished for higher
pressure drops. Some erosion of valve disks occurs at all pressure drops due to solid particles in the ow stream. The rate of erosion is higher with large amounts of impurities in the ow stream
and with high pressure drops. Valve disks and other regulator parts must be inspected periodically for erosion and damage and must be replaced as necessary.

1. Damage to internal parts of the regulator may occur if outlet pressure exceeds the actual pressure setting by amounts greater than those shown in this column.
2. For outlet pressure settings to 1.7 bar / 25 psig only. For pressure settings over 1.7 bar / 25 psig, outlet pressure is limited by maximum emergency outlet pressure of 3.1 bar / 45 psig.
3. For outlet pressure settings to 24.1 bar / 350 psig only. For pressure settings over 24.1 bar / 350 psig, outlet pressure is limited by maximum emergency outlet pressure of 37.9 bar / 550 psig.
4. Leakage or bursting of pressure-containing parts may occur if outlet pressure exceeds these values.

Vents
!
When the unit is installed in an enclosed
area or indoors, escaping gas may
accumulate and be an explosion hazard.
Under these conditions the vent should
be piped away from the unit to a freely
ventilated outdoor location away from
air intakes, windows, etc. Protect all
vent openings against weather or the
entrance of any foreign material that
may plug the vent or aect operation of
the regulator or relief valve. Inspect all
vent openings periodically to be sure
they are not plugged. If the vent is in
the environment where freezing rain,
ice or snow could clog the vent, it is
recommended that a weatherproof vent
be used.
Spring-loaded constructions have a screened vent
assembly (key 27, Figures 1, 2 and 3) installed in the
1/4 NPT spring case vent opening. If a remote vent
is required, remove the vent assembly and install a
remote vent line.
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.
Regular 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.
