Installation

Piping Cleanliness

Before installing the valve in the line, clean piping and valve of all

foreign material such as welding chips, scale, oil, grease or dirt.

Gasket mating surfaces must be thoroughly cleaned to ensure

leak-free joints. Sacrificial start-up fixtures can be purchased from

Baker Hughes to protect the operational trim during the installa-

tion and line flushing phases.

CAUTION

WARNING

DANGER

If major system or piping modications (or repairs) are

performed, thorough ushing and blowdown of the

system will be required prior to reinstalling the trim.

Sacricial ushing trim should be installed in the valve

to protect the integrity of the ow passages. Failure to

follow this warning will violate the valve warranty agree-

ment and could result in control instability, excessive

noise levels, and valve leakage.

Isolation Bypass Valve

To allow for in-line inspection, maintenance and removal of the

valve without service interruption, provide a manually operated

shutoff valve on each side of the control valve and a manually

operated throttling valve in the bypass line.

Heat Insulation

In case of a heat-insulated installation, do not insulate the valve

bonnet and take protective measures relative to personal safety.

Hydrostatic Testing and Line Cleaning

During this operation, the control valve must not be used as an

isolating valve. This means that the valve must always be opened

before carrying out pressure tests in the process line, cleaning

of pipes, etc. otherwise equipment damage or failure of the seal

rings could result. If the valve is to remain installed during line

cleaning, flushing trim MUST be installed to prevent damage to

trim components.

Flow Direction

The valve must be installed so that the process fluid will flow

through the valve in the direction indicated by the flow arrow

located on the body.

Welded Connections

CAUTION

WARNING

DANGER

Carefully review the information in this section prior to

welding any valves inline. Refer any additional ques-

tions to the local Baker Hughes Sales Ofce or Service

Center.

Pre-Weld Preparation

Carefully follow the installation steps defined in the sections noted

above prior to performing weld procedures.

Welding Process

Perform welding process in accordance with the standard

requirements for the materials and weld construction of the specific

valve. Apply post weld heat treatment if required.

CAUTION

WARNING

DANGER

Internal valve components should be removed prior

to performing welding or pre/post weld heat treatment

weld heat treatment in order to prevent damaging any

soft goods (such as PTFE seals). If unable to remove

the elastomeric components, then other methods must

be employed to prevent the local temperature around

the seals from exceeding the maximum material limits

(typically 450°F / 232°C for PTFE based materials).

Post Weld Cleaning & Assembly

Inspect the body, bonnet, and trim components for cleanliness and

surface condition. Remove any foreign materials, such as weld

chips, slag or scale. Make sure there are no nicks, scratches, burrs

or sharp corners on sealing and sliding surfaces. Clean all gasket

interface surfaces and reassemble using new gaskets to ensure

sealing integrity.

Actuator Assembly

Assemble the pneumatic actuator onto the control valve using the

appropriate instructions for the specific actuator model and type.

Connect air pressure lines to the actuator ports to meet intended

operating mode (i.e., air-to-extend, air-to-retract, or double-acting).

Disassembly

CAUTION

WARNING

DANGER

Prior to performing any maintenance on the valve, iso-

late the valve and vent the process pressure.

Valve Actuation

Access to the internal components of the valve should be

accomplished with the actuator removed. Follow the detailed

instructions below and refer to the appropriate actuator

instruction manuals.

CAUTION

WARNING

DANGER

Actuator may be pre-loaded with tension from air pres-

sure or springs. Prior to disconnecting instrumentation

read all instructions for the specic actuator.

Disconnect Instrumentation

Disconnect all mechanical connections between the positioner and

the other instruments. Disassemble the valve stem and actuator

stem coupling as described in the following sections.

Air-to-Retract Actuators

Apply sufficient air pressure to the actuator to retract the stem

completely. Disconnect the plug stem from the actuator stem

depending on the connection type as described below.

Threaded Connection

Unscrew the plug stem from the actuator stem, making sure the

plug never contacts the seating area (liner or seat ring) at any

time during disassembly.

CAUTION

WARNING

DANGER

Contact between the plug and seating area during this

disassembly process may cause damage to the seating

surfaces. It may be necessary to disassemble the actua-

tor yoke from the valve bonnet and lifting the actuator

off the valve to avoid plug to seating surface contact.

Split Clamp Connection

Remove the screws and disassemble the stem connector from the

valve and actuator stem.

Air-to-Extend Actuators

For this actuator configuration, the valve plug is already in the fully

retracted position without any air pressure applied. Disconnect

the plug stem and actuator stem as described in the threaded

connection and stem connector sections above depending on the

connection type.

Actuator Removal

Disconnect all electrical and air connections to and from the

actuator. Disassemble yoke nut or yoke attachment screws, and

lift the actuator off of the valve being careful not to damage the

bonnet threads

Valve Disassembly

The valve must always be reassembled with new packing set and

gaskets. Before disassembly, make sure the recommended spare

parts are available for reassembly.

1. Disconnect the piping to the leak detector connection on the

bonnet (if applicable).

2. Remove the packing flange nuts (19) then remove the packing

flange (17) and the packing follower (16).

3. Check the exposed part of the valve stem (8) to confirm it is

clean enough for ease of removal of the bonnet (2).

4. Remove the body nuts (13).

For valve configurations designed with a two piece bonnet

assembly (bonnet and bonnet flange):

5. Disassemble the bonnet flange (3) from the valve body (1).

6. Lift the bonnet (2) and metal seal (11) to remove from the

valve body (1). During this operation, the valve stem (8) must

be pushed downward to ensure the valve plug (6) remains

inside the valve body.

Note: The metal seal (11) will require some force to

remove from the bonnet (2). Using a common tool, such

as a small pry bar, lever the seal up at various points to

lift out evenly.

7. Remove the cage gasket (10A) from the top of the valve

cage (4). Proceed to step 10.

For valve configurations designed with a single piece bonnet:

8. Lift the bonnet (2) and remove from the valve body (1).

During this operation, the valve plug stem (8) must be pushed

downward to ensure the valve plug (6) remains inside the

valve body (1).

9. Remove the body gasket (Not Shown) from the groove on top

of the valve body (1).

10. Remove the valve plug assembly (6) from the valve cage by

pulling the valve plug stem (8) upward.

11. Remove the cage (4) by lifting the part out of the valve

body (1).

12. Remove the seat ring (5) by lifting the part out of the valve

body (1).

groove of the seat ring.

13. Remove the lower seat ring gasket (24) from the valve body

(1).

14. Remove the packing set (11) and the guide bushing (26)

from the bonnet (2).

Plug Stem Disassembly

CAUTION

WARNING

DANGER

The valve plug assembly is screwed and pinned to en-

sure stability and performance. Due to the critical pur-

pose of the plug assembly and tolerance requirements,

Baker Hughes highly recommends avoiding in the eld

maintenance of this part. The plug assembly should be

purchased as a complete assembly. However, if urgent

eld repair is required, follow the instructions below.

The valve plug stem is screwed into the valve plug (6) and pinned.

To disassemble the stem, the valve plug must be held as shown

below in Figure 1, taking care not to damage the guiding surfaces.

Figure 1: Correct Plug Clamping Surface

By means of flats or using a nut and counter-nut on the end of the

stem, unscrew the stem from the plug taking care not to apply a

bending movement which could deform it.

Maintenance & Repair

The purpose of this section is to provide recommended

maintenance and repair procedures. These procedures assume

the availability of standard shop tools and equipment.

Maintenance

Packing Box

Tight sealing within the packing box is obtained by compression

of the packing (15). Compression must be achieved by evenly

tightening the packing flange nuts (19) on the packing flange (17).

Periodic re-tightening of the packing flange nuts may be required

to maintain proper sealing.

CAUTION

WARNING

DANGER

Be careful not to over tighten the packing as this

could prevent proper operation of the valve. If leakage

persists after maximum packing compression, then the

packing needs to be changed.

PTFE Packing

Carbon/PTFE and pure PTFE packing rings are cut in such a way

that they can be replaced without having to separate the valve plug

stem from the actuator stem.

1. Unscrew and remove the packing flange nuts (19).

2. Lift the packing flange (17) and packing follower (16) up along

the valve stem (8).

3. By means of a puller, remove the packing (15) being careful

not to damage the sealing surface of the packing box or the

valve plug stem.

4. Replace the packing rings, placing the cut in each ring about

120° apart from the adjacent ring. Press rings in one at a time.

5. Reassemble the packing follower (16) and the packing flange

(17).

6. Tighten the packing flange nuts (19) without over compressing

the packing rings.

7. Put the valve back into service and check for leakage.

8. Tighten packing flange nuts (19) as required.

Valve with Graphite Packing

To replace Graphite packing, it is necessary to separate the valve

plug stem from the actuator stem.

1. Remove the packing flange nuts (19) from the packing flange

studs (18).

2. Lift the packing flange (17) and packing follower (16) up along

the valve stem (8).

3. By means of a puller, remove the packing (15) being careful

not to damage the sealing surface of the packing box or the

valve plug stem.

4. Replace the packing (15). Press a back-up ring (carbon/

graphite/Inconel braided ring) into the bonnet (2). Next press

the expanded graphite rings into the packing area one at a

time. Press an additional back-up ring into packing area.

5. Reassemble the packing follower (16) and the packing flange

(17).

6. Tighten the packing flange nuts (19) without over- compressing

the packing rings.

7. Open and close the valve several times then retighten the

packing as required.

8. Put the valve back into service and check for leakage.

9. Tighten packing flange nuts (19) as required.

Repair of Parts

Prior to reassemble, examine parts carefully for any scratches,

unusual wear, or other damage.

Guiding Surfaces

Guiding surfaces of the cage, valve plug, guide bushing, plug

stem, and auxiliary pilot plug must be checked. See Figures 2

and 3. If there are only slight wear indications, then gently use a

light abrasive, such as fine grit sandpaper, to smooth out guiding

surfaces. Parts with greater damage or wear on the guiding

surfaces must be replaced.

Seating Surfaces

The seat ring seating surface and valve plug seating surface must

be completely free of dents, wear, or scratches. Consult factory

should you see any signs of slight deterioration prior to attempting

touchup. If a slight defect exists on either the seat ring seating

surface or the valve plug seating surface, lapping can be applied

per the following instructions.

1. CIean body gasket surface areas.

2. Install a new seat ring gasket (10B).

Note : Seat ring gasket (10B) is temporarily placed to hold

the seat ring during lapping.

It is imperative to use a new gasket or a test part having

the same geometrical characteristics in order to insure

the correct position of the seat ring during lapping.

Figure 2

Metal Seal

For the two piece bonnet configurations:

Prior to reassembly, the metal seal (11) should be inspected for

cracks or signs of wear. The metal seal can be reused if it is free

from scratches, erosion, corrosion, or any other type of damage.

If slight wear exists on the metal seal, a new layer of coating should

be re-applied to the original condition by the factory or a Masoneilan

Authorized Repair Center.

Prior to reassembly of the valve, inspect the inside of the valve

body around the area where the metal seal seats. It is common to

find slight ridges or depressions from where the seal was originally

seated. During initial assembly these depressions aid in the sealing

of the valve, however these areas can become leak paths during

reassembly if the surface is not restored to its original finish as

described below.

Figure 4

To prevent this potential leakage, machine the seating angle of the

bonnet at 40 degrees by approximately 0.1 inches (2.5 mm) deep,

thus causing the metal seal to seat further down inside the valve

body (on a new un-deformed surface). Refer to Figure 4 for details.

If this procedure is required more than twice please consult factory.

Valve Plug

If the valve plug needs to be repaired see instructions for Valve

Re-assembly.

Valve Reassembly

Pinning the Valve Plug

The valve plug assembly consists of a stem (16) that is threaded

into The valve plug assembly consists of a stem (8) that is threaded

into the valve plug (6). To secure this assembly, the stem (8) is then

pinned (9) to the valve plug (6).

If the valve plug (6) or stem (8) needs to be replaced, an entire

assembly should be purchased from the factory to ensure product

strength and integrity. Re-machining of these parts in the field can

seriously impair the mechanical strength and integrity of the valve

plug stem assembly.

Completing Valve Body Assembly

Proceeds as follows:

Seat Ring Installation

1. After checking all sealing surfaces to ensure they are

thoroughly clean, assemble the seat ring gasket (10B) in the

valve body (1). Make sure the gasket is centered properly in

the body.

This gasket (or similar part) can be kept after lapping for

future lapping use.

Figure 3

The gasket used for lapping must not be reused for the body

reassembly.

3. Place seat ring (5) or seat ring diffuser (Not Shown) in the

body, noting the seating angle is up.

4. Spread a fine layer of high quality lapping compound (600 grit)

on the seating surface.

5. Assemble the cage (4) and (if applicable) cage retainer (Not

Shown) and the plug assembly (Items 6, 8 & 9) into the valve

body (1) per the valve plug assembly instructions.

6. Assemble the bonnet (2) and the guide bushing (7).

7. Place an appropriate tool on the valve stem (8) thread to allow

for manual rotation.

8. Lap by slightly rotating the valve plug in alternate directions.

9. After several rotations, lift the valve stem, turn it 90 degrees,

and repeat the operation.

10. Lapping can be repeated, but should be limited as much

as possible so that the seat remains sufficiently narrow to

guarantee tightness.

11. After lapping, disassemble the parts to clean them and then

reassemble, making sure the seating angles are within

tolerance. See Figure 3.

Note: For more details on the lapping procedure and

seating angles, please consult the factory and provide

the valve serial number (found on the serial plate on the

actuator).

Gaskets

Gasket seating surfaces must be free of dents, scratches,

corrosion, or other types of damage. Clean mating surfaces as

required and replace any non-conforming parts. Spiral wound

gaskets (10) must always be replaced after disassembly.

Seal Rings

Seal rings (14), back-up rings (22), retaining ring (Not Shown),

and conical springs (Not Shown) can be reused if they are free of

scratches, erosion, corrosion, or other damage.
