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

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.

4.2.1 Apply air pressure to port 2 on FCW (port 4 on FCCW)
actuator, raising pressure slowly, enough to release
spring pressure from the Stop Bolt (17). Back off fully
both Stop Bolts on the Torque Module and release air
pressure. This will relieve the spring preload.

4.2.2 The Spring Module is welded into an integral compo­nent and cannot be disassembled. To remove from ac­tuator, remove Spring Module end cover (60) and us­ing an extended socket spanner /tube spanner, unscrew
and disconnect the Pull Rod (54) from the Torque Mod­ule.

CAUTION! Take extra care not to drop the socket/small

tools inside the spring can. Small objects dropped in­side may fall through the spring guide and get stuck
in the spring coils.

NOTE: A retainer ring on the threaded side of the Pull

Rod stops it from being removed completely from the
Spring Module.

4.2.3 Sling the Spring Module using lifting bolts on the Mod­ule and remove the Adapter Nuts (19) and Lock wash­ers (20).Spring Module can now be removed from the
Torque Module.

4.2.4 Before reassembling Spring Module to body, make sure
stud threads are clean of any dirt, shavings, or other
debris. Clean threads with rag and solvent if required,
and lubricate threads with an anti-seize compound.

NOTE: Support the Spring Module during removal so

as not to damage the Pull Rod and the studs’ threads.

Thread Plugs (31).

4.4.4 Using the removed Body Cover Bolts, jack open the
cover by threading in the bolts in the two tapped
holes until cover is separated enough to pry apart.
Take care to jack the bolts evenly, as the cover is
positioned by four dowel pins, and cross loading
may cause bending/ breakage of pins on small ac­tuator sizes.

4.4.5 Gently tap with PU/Plastic hammer and pull off the
Guide Bar (2) from the body.

4.4.6 Lift Yoke Sub Assembly out of body bore.

4.4.7 Remove Delrin Plate (7) retaining screws. Pull out
the Yoke Pin (9), and Slider Block (10).

4.4.9 Remove Yoke Seals (5) and Yoke Bushing (4) if
worn out/damaged.

4.5 Reassembly Instructions

4.5.1 Inspect all parts for wear and replace any worn
parts as needed. Normally, all O-rings and seals
should be replaced when reassembling an actuator.
Use seal lubricant, Dow Corning 55 for all lubrica­tion in the pressure group.

Ensure the replacement seals are suitable for the

service temperature.

4.5.2 The Metal backed bronze-ptfe bearings may be in­spected and assessed for replacement, referring to
guide (see Fig.: 2) on the useful residual life

To replace the bearings, the unit or the subassembly

needs to be brought in to workshop, with suitable
facilities to carefully remove the bearing without
damaging the housing and to press new bearing
with proper pressing tools per manufacturer’s in­structions and a press.

Do not attempt to pry out any of the bearings in the

actuator with sharp tools, or hammer in a replace­ment bearing.

4.5.3 Clean thoroughly and grease all Torque Module
components with NLGI grade 2 multi-purpose
grease. Use Shell Alvania EP2 for Standard Actua­tors. For low temperature units, use Dow 55 grease
or equivalent.

chart, on the Tie Rod Locknuts, the Mounting Flange
Nuts, the Body Cover & Top Plate bolts, the Piston
Rod / Pull Rod (see tables on pafe 7.

The Tie Rod and Mounting Flange Stud threads

should be lubricated with Locktite Antiseize, 77164
or equivalent.

The Pull /Piston Rod threads and cover bolts to be

tightened with thread lock compound, Loctite 243
or equivalent.

4.5.5 Refer to parts and materials drawings for all re­quired spare parts (see pages 9 + 10).

Test the actuator for smooth operation and air

leakage at service pressure before reinstalling into
service.

5 Field Conversion from Fail CW to Fail CCW

(For Spring Return Actuators)

The RG spring return actuator can be converted from

fail CW to fail CCW easily, without having to remove the
Torque Module, mounting bracket, stem adaptor and
the shaft driven accessories, mounted on the centre
body . Simply switch the positions of the Pressure and
Spring Modules.

Actuator Designation needs to be suitably changed on

the name plate.

Follow steps below, if operating the valve is permitted:

5.1 Apply enough air pressure to the actuator to relieve
spring load on the stopper bolt.

5.2 Back off both the stopper bolts on the Torque Module
and depressurize the actuator.

5.3 Remove Spring Module end cover, unscrew and dis­connect the Spring Pull Rod.

5.4 Pressurize rod end of Pressure Module, to end of
stroke. Depressurize and remove the end cover/plug
on the Pressure Module. Use a tube/socket spanner,
loosen piston rod by one turn, fit back end cover/plug
and pressurize cap end, enough to stroke to end. De­pressurize, remove end cover/plug and fully unscrew
and disconnect the piston rod from the Torque Module.

5.5

Remove the Pressure and Spring Modules off the Torque
Module by removing the mounting flange stud nuts.

It is recommended to take precautions and certain

measures when storing the actuators for extended
periods of time, more than 4 months to two years.

Potential problems and recommended protections

are as below:

Potential Problem Protection

Water entry into pneumatic cylinder, degrades the cylinder, par­ticularly in saline or corrosive environment.
Temperature swings cause condensation inside cylinders

Seal compression set Cycle actuator 5-6 times with clean dry instrument air or nitro-

Degradation of seals in excessively corrosive or hot environ­ments

Physical damage to actuator or accessories. Store actuator assembly on skid, off the floor, out of pathways.

• Store actuator in clean, dry and protected warehouse, or un­der ventilated dust cover.

• Plug all ports after purging with dry instrument air or nitro­gen.

• Store vertical, to avoid seal set.

gen, every 3 months.

• Do not store in locations subjecting the actuator to tem­peratures in excess of seal rating. Std seals are Nitrile, max
temp 180deg F.

• Do not store in environments harmful to resilient seals.

Inspect the protections every 3 months and record inspection results.
