User Instructions RG Series Standard Actuator - AXENIM0122-00 12/09

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 us-

ers 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 ap-

plications 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 infor-

mation 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.

NOTE: indicates and provides additional technical

information, which may not be very obvious even

to qualified personnel.

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 per-

forming 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.).

1.4 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 author-

ised 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 oc-

cur 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.

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 pro-vided (a form can be obtained from FLOWSERVE).

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.

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.

User Instructions RG Series Standard Actuator - AXENIM0122-00 12/09

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 in-

doors 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, fol-

low 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. Con-

tinue 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.

2.4 Adjust the travel stop bolts of the actuator for the proper

open and closed valve positions, per valve manufactur-

er’s recommendations. Pneumatically stroke the actua-

tor several times to assure proper operation. The stem

adaptor should not bind during operation. If the actua-

tor is equipped with an UltraSwitch or other accesso-

ries, adjust them at this time.

2.5 To prolong actuator life use only clean, dry plant air. Lu-

bricated air is not required, however it is recommended

particularly for high cycle applications. Do not use lubri-

cated 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 Maintenance Instructions

4.1 Disassembly Instructions

4.1.1 Disconnect all air and electrical supplies from actuator.

4.1.2 Remove all accessories from actuator and dismount ac-

tuator from valve.

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 compo-

nent and cannot be disassembled. To remove from ac-

tuator, remove Spring Module end cover (60) and us-

ing an extended socket spanner /tube spanner, unscrew

and disconnect the Pull Rod (54) from the Torque Mod-

ule.

CAUTION! Take extra care not to drop the socket/small tools inside the spring can. Small objects dropped in-side 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 Mod-

ule and remove the Adapter Nuts (19) and Lock wash-

ers (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.

4.3 Pressure Module

4.3.1 Pressurize rod end of cylinder, enough to stroke to end.

Vent out the air from the cylinder.

4.3.2 Remove end cover plate/plug from pressure module

and unscrew the piston rod with a socket/tube spanner.

4.3.3 Sling the pressure module from the eye bolts, remove

the Adaptor Stud Nuts (19) and Lock washers (20) and

take the Pressure module off the Torque module.

4.3.4 Remove the Tie Rod Nuts (37), the End Plate (33) and

Tie Rods (36).

4.3.5 Slide the Cylinder (34) over and off the Piston (38), be-

ing careful not to scratch or dent the honed and chrome

plated surface of the cylinder.

4.3.6 Slide out the Piston- Piston Rod assembly off the

Adapter Plate (32).

4.3.7 Remove the Retainer Ring (40) and take the Split

Collar (39) off the Piston Rod (35).Pull the Piston

Rod off the Piston.

4.4 Torque Module (Body Group)

NOTE: Spring Module and Pressure Module must be removed before disassembling the Torque Module

4.4.1 Remove the Indicator (29), if fitted.

4.4.2 Remove Top Cover Bolts (65) and the cover, O-ring

and the Namur Shaft Assembly (15).

4.4.3 Remove Body Cover Bolts, Lock Washers (26) and

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 ac-

tuator 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).

4.4.8 Slide out the Guide Block (11) out of the Yoke and

remove the bottom Slider Block.

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 lubrica-

tion 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 in-

spected 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 in-

structions and a press.

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

actuator with sharp tools, or hammer in a replace-

ment 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 Actua-

tors. For low temperature units, use Dow 55 grease

or equivalent.

4.5.4 Reverse the disassembly procedures to reassem-

ble. Apply recommended torque, refer torque

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 re-

quired 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 dis-

connect 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. De-

pressurize, 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.

5.6 Switch the positions of the two modules, connect the

Pressure Module first and ensure the ports are on the

stopper bolts side of actuator. Thread in and torque the

piston rod to recommended value, fit back end cover

plate/plug. Pressurize cap end to stroke the actuator to

end.

5.7 Reinstall Spring Module, torque the pull rod to recom-

mended value, fit end cover back. Pressurize rod end of

cylinder and adjust the stopper bolts.

5.8 Check actuator for proper operation, at the rated work-

ing pressure.

NOTE: If operation of valve is not permitted, during changing of the Fail Safe direction, then the actuator needs to be taken off the valve and reconfigured, as explained above.

7 Long Term Storage

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:

6 Torque Shaft

The output shaft is recommended to have two key en-

gagements. Shaft material shall be alloy steel with mini-

mum yield strength of 85,000psi. The recommended

hardness of keys is 25-28HRc.

Recommended engagement length of the keys is as be-

low (see Fig.: 3).

Potential Problem Protection

Water entry into pneumatic cylinder, degrades the cylinder, par-

ticularly in saline or corrosive environment.

Temperature swings cause condensation inside cylinders

• Store actuator in clean, dry and protected warehouse, or un-

der ventilated dust cover.

• Plug all ports after purging with dry instrument air or nitro-

gen.

• Store vertical, to avoid seal set.

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

gen, every 3 months.

Degradation of seals in excessively corrosive or hot environ-

ments

• Do not store in locations subjecting the actuator to tem-

peratures in excess of seal rating. Std seals are Nitrile, max

temp 180deg F.

• Do not store in environments harmful to resilient seals.

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

Inspect the protections every 3 months and record inspection results.
