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.
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. Use suitable line gaskets and approved piping
and bolting practices. Install the regulator in any position
desired. However, to ensure self-draining (from outlet
to inlet) the regulator should be installed with the spring
case in the upright vertical position. The arrow on the
body indicates ow direction.
Note
It is important that the regulator be installed
so that the vent hole in the spring case is
unobstructed at all times.
Tri-Clamp® is a mark owned by Tri-Clover Incorporated.
1. The pressure/temperature limits in this installation guide and any applicable standard or code limitation should not be exceeded.
2. Maximum pressure to prevent damage to internal parts and leakage to atmosphere.
3. End connection clamps and gaskets to be supplied by the user.

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. Make sure the CIP/SIP Pin (key 30, Figure 1) is
not installed in the spring case. With proper installation
completed and relief valves properly adjusted, slowly
open the upstream and downstream shutoff valves.
!
WARNING
The CIP/SIP pin must be removed before
regulator is placed in operation. The pin will
inhibit the proper operation and function of
the regulator and result in overpressure of
the downstream system.
Adjustment
To change the outlet pressure, remove the closing cap
or loosen the locknut and turn the adjusting screw or
handwheel 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.

Pressure-Loaded Construction
The spring case can be pressure loaded to adjust outlet
pressure. An optional tapped spring case, guide ring
seal and sealing washer on the adjusting screw must
be used for these applications. The loading pressure is
connected to the 1/4 NPT connection in the spring case
allowing registration on the spring side of the diaphragm.
Adjusting loading pressure will proportionally change the
outlet pressure setting of the regulator. A small amount of
mechanical spring load, in addition to the pressure load,
is recommended. Regulator set pressure achieved from
the combination of spring load and pressure load should
not exceed the outlet pressure ranges listed on Table 2.
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. Relieve all spring
compression and isolate regulator from
the pressurized system prior to removing
the clamp (key 15, Figure 1).
