Compliance with other, not particularly emphasised
notes, with regard to transport, assembly, operation and
maintenance and with regard to technical documentation
(e.g. in the operating instruction, product documentation
or on the product itself) is essential, in order to avoid
faults, which in themselves might directly or indirectly
cause severe personal injury or property damage.
1.3 Protective clothing
FLOWSERVE products are often used in problematic
applications (e.g. extremely high pressures, dangerous,
toxic or corrosive mediums). In particular valves with
bellows seals point to such applications. When performing service, inspection or repair operations always
ensure, that the valve and actuator are depressurised and
that the valve has been cleaned and is free from harmful
substances. In such cases pay particular attention to
personal protection (protective clothing, gloves, glasses
etc.).
1 Using Flowserve Valves, Actuators and Acces-
sories Correctly
1.1 General usage
The following instructions are designed to assist in
unpacking, installing and performing maintenance
as required on FLOWSERVE products. Product users and maintenance personnel should thoroughly
review this bulletin prior to installing, operating or
performing any maintenance.
In most cases FLOWSERVE valves, actuators and
accessories are designed for specific applications
with regard to medium, pressure and temperature.
For this reason they should not be used in other applications without first contacting the manufacturer.
1.2 Terms concerning safety
The safety terms DANGER, WARNING, CAUTION
and NOTE are used in these instructions to highlight
particular dangers and/or to provide additional information on aspects that may not be readily apparent.
DANGER: indicates that death, severe personal
injury and/or substantial property damage will occur
if proper precautions are not taken.
WARNING: indicates that death, severe personal
injury and/or substantial property damage can occur
if proper precautions are not taken.
CAUTION: indicates that minor personal injury and/
or property damage can occur if proper precautions
are not taken.
1.4 Qualified personnel
Qualified personnel are people who, on account of their
training, experience and instruction and their knowledge
of relevant standards, specifications, accident prevention
regulations and operating conditions, have been authorised by those responsible for the safety of the plant to
perform the necessary work and who can recognise and
avoid possible dangers.
1.5 Installation
DANGER: Before installation check the order-no.,
serial-no. and/or the tag-no. to ensure that the valve/
actuator is correct for the intended application.
Do not insulate extensions that are provided for hot or
cold services.
Pipelines must be correctly aligned to ensure that the
valve is not fitted under tension.
Fire protection must be provided by the user.
1.6 Spare parts
Use only FLOWSERVE original spare parts. FLOWSERVE
cannot accept responsibility for any damages that occur from using spare parts or fastening materials from
other manufactures. If FLOWSERVE products (especially
sealing materials) have been on store for longer periods
check these for corrosion or deterioration before using
these products. Fire protection for FLOWSERVE products
must be provided by the end user.
NOTE: indicates and provides additional technical
information, which may not be very obvious even
2
to qualified personnel.

1.7 Service / repair
To avoid possible injury to personnel or damage to
products, safety terms must be strictly adhered to.
Modifying this product, substituting nonfactory parts,
or using maintenance procedures other than outlined
in this instruction could drastically affect performance
and be hazardous to personnel and equipment, and may
void existing warranties. Between actuator and valve
there are moving parts. To avoid injury FLOWSERVE
provides pinch-point-protection in the form of cover
plates, especially where side-mounted positioners are
fitted. If these plates are removed for inspection, service
or repair special attention is required. After completing
work the cover plates must be refitted.
Apart from the operating instructions and the obligatory
accident prevention directives valid in the country of
use, all recognised regulations for safety and good
engineering practices must be followed.
WARNING: Before products are returned to FLOWSERVE
for repair or service FLOWSERVE must be provided
with a certificate which confirms that the product has
been decontaminated and is clean. FLOWSERVE will
not accept deliveries if a certificate has not been provided (a form can be obtained from FLOWSERVE).
1.10 Unpacking
Each delivery includes a packing slip. When
unpacking, check all delivered valves and accessories
using this packing slip.
Report transport damage to the carrier immediately.
In case of discrepancies, contact your nearest
FLOWSERVE location.
1.8 Storage
In most cases FLOWSERVE products are manufactured
from stainless steel. Products not manufactured from
stainless steel are provided with an epoxy resin coating.
This means that FLOWSERVE products are well protected
from corrosion. Nevertheless FLOWSERVE products
must be stored adequately in a clean, dry environment.
Plastic caps are fitted to protect the flange faces to
prevent the ingress of foreign materials. These caps
should not be removed until the valve is actually mounted
into the system.
1.9 Valve and actuator variations
These instructions cannot claim to cover all details of
all possible product variations, nor can they provide
information for every possible example of installation,
operation or maintenance. This means that the
instructions normally include only the directions to
be followed by qualified personal where the product
is being used for is defined purpose. If there are any
uncertainties in this respect particularly in the event of
missing product-related information, clarification must
be obtained via the appropriate FLOWSERVE sales office.

Introduction
The RG Series is a fully modular design, scotch-yoke ac-
tuator; with torque range from 2000Nm to 250,000Nm
(2,800 in-Lbs to 2.2 M in-Lbs) in eight models, RG1
through RG8, with maximum actuator torque and
mounting base in compliance with ISO 5211.
The RG series Spring Return Actuators, in contrast with
R-series, use Pull-to-Compress the spring design.
2 Installation
2.1 All actuators are factory lubricated for life, but still
should be protected from the elements and stored indoors until ready for use. The ports of the actuator are
plugged as supplied from the factory. If actuators are
stored for a long period of time prior to installation, follow the Long Term Storage instructions.
2.2 Prior to assembly, manually open and close valve (if
possible), to ensure freeness of operation. Be sure,
valve and Automax actuator rotate in the same direction
and are in the same position (i.e., valve closed, actuator
closed).
2.3 Check the mounting surfaces, the stem adaptor and
the bracket to assure proper fit. Secure the valve in the
closed position with the stem vertical. Bolt the bracket
to the valve and place the stem adaptor on the valve
stem. Position the actuator over the valve and lower, to
engage the stem adaptor to the actuator’s bore. Continue to lower until the actuator seats on the bracket
mounting surface. In order to align the bolt holes, it
may be necessary to loosen the valve-to-bracket bolting
to allow more play in the bracket. The mounting bolts
should easily fit into the bolt holes without any binding.
If needed, turn or stroke the actuator a few degrees and/
or adjust the actuator travel stops. Bolt the actuator to
the bracket.
tor several times to assure proper operation. The stem
adaptor should not bind during operation. If the actuator is equipped with an UltraSwitch or other accessories, adjust them at this time.
2.5 To prolong actuator life use only clean, dry plant air. Lubricated air is not required, however it is recommended
particularly for high cycle applications. Do not use lubricated air with positioners.
CAUTION! Lifting bolts holes on the actuator are for
lifting the actuator modules only with eye bolts, not a
complete valve and actuator assembly.
3 Travel Stop Adjustments
All actuated valves require accurate travel-stop adjust-
ments at both ends of the stroke to obtain optimum
performance and valve seat life. The accumulation of
tolerances in the adaption of actuators to valves is such
that there must be a range of adjustments for both ends
of the stroke to achieve optimum performance.
The RG actuators have travel stop adjustments in both
the clockwise and counter-clockwise directions. The
+/- 3 degree adjustment feature provides shaft rotation
from 84 to 96 degrees.
