Description

The 8510B flangeless control valve has an eccentrically mounted disc that self-centers in the line during installation. The valve includes built-in electrical bonding of the shaft to the valve body. This valve has either a splined shaft for use with power, handwheel, or handlever rotary actuators, or a double D end connection with anti-blowout shaft for use with 1035 Rack and Pinion actuators and other quarter-turn actuators. It is used for throttling or on/off control of a wide variety of liquids and gases. The 8510B is a balanced construction available in CL150 through 600. Figure 8 illustrates the various constructions.

Specifications

Specifications for the 8510B valve body are shown in table 1.

Installation

Key numbers in this procedure are shown in figure 8 unless otherwise indicated.

WARNING

Always wear protective gloves, clothing and eyewear when performing any installation operations to avoid personal injury.

To avoid personal injury or property damage resulting from the bursting of pressure retaining parts, be c ertain the service conditions do not exceed either the valve body rating or the flange joint rating, or other limits given in table 1 or on the nameplate. Use pressure-relieving or pressure-limiting devices to prevent the service conditions from exceeding these limits.

If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this instruction manual.

CAUTION

The valve configuration and construction materials were selected to meet particular pressure, temperature, pressure drop, and controlled fluid conditions specified in the customer's order. Because some valve body/trim material combinations are

The maximum allowable inlet pressures for steel, stainless steel, alloy 20, and M35-1 valve bodies are consistent with the pressure-temperature ratings shown in table 2, except where further limited by the trim and packing material temperature capabilities given in table 3.

1. Install a three-valve bypass around the control valve assembly if continuous operation is necessary during inspection and maintenance of the valve body.

2. Inspect the valve body to be certain that it is free of foreign material.

3. The valve is normally shipped as part of a control valve assembly, with a power or manual actuator mounted on the valve body.

If the valve body and actuator have been purchased separately or if the actuator has been removed for maintenance, mount the actuator, and adjust actuator travel before inserting the valve body into the line. This is necessary due to the measurements that must be made during the actuator adjustment process. Refer to the Actuator Mounting

Instruction Manual

D251400X012

8510B Valve (EMA)

section of this manual and to the separate actuator instruction manual for mounting and adjusting instructions before proceeding.

4. Be certain that adjacent pipelines are free of any foreign material, such as pipe scale or welding slag, that could damage the valve body seating surfaces.

CAUTION

Damage to the disc (key 3) will occur if any pipe flanges or piping connected to the valve body interfere with the disc rotation path. However, the disc can be rotated without interference when the valve body is installed between adjacent pipe flanges or piping that has an inside diameter equal to or greater than either schedule 80 pipe or compatible DIN or JIS pipe sizes. If piping with a smaller inner diameter than specified above is connected to the valve, measure carefully to be certain the disc rotates without interference before putting the valve into operation.

5. Flow is in the standard direction when the seal retainer (key 2) is facing upstream. Standard flow direction is also indicated by the flow direction arrow cast into the valve body. Flow in the reverse direction is permissible.

CAUTION

Rotating the disc (key 3) past either t he open or closed position could damage the seal and disc sealing surfaces and could cause the disc to jam in the valve body bore. The disc stop should be zeroed in its flat position as shown in figure 7. Do not use the disc stop as a travel stop for the actuator. Use the actuator travel stop provisions.

6. With the disc in the closed position, install line flange gaskets, and insert the valve between the pipeline flanges. Use either flat sheet gaskets or spiral-wound gaskets with compression-controlling centering rings. Spiral-wound gaskets without compression-controlling centering rings are not recommended for this purpose. Composition gaskets may be used to 343_C (650_F), and the optional FGM gaskets (key 29, not shown) may be used for —129 to 538_C (—200 to 1000_F) temperatures.

7. There are four flange bolt holes in the valve body (key 1), and each hole engages one corresponding line flange stud. Insert the valve between the flanges and i nstall the four line flange studs to roughly center the valve body in the pipeline.

8. After centering the valve body, first lubricate and then install the remaining line flange studs to secure the valve in the pipeline. Tighten the nuts to the line flange studs in a crisscross sequence to ensure proper alignment of the valve body with the flanges.

Instruction Manual

D251400X012

WARNING

An 8510B valve body is not necessarily grounded when installed in a pipeline. If the valve is used in a flammable or hazardous atmosphere or for oxygen service, an explosion could result due to a discharge of static electricity from the valve components. To avoid personal injury or property damage, always make sure that the valve body is grounded to the pipeline before putting the control valve assembly into operation in a flammable or hazardous atmosphere.

Note

Standard 8510B packings are composed of all conductive packing rings (graphite ribbon packing) or partially conductive packing rings (such as a carbon-filled PTFE female adaptor with PTFE V-ring packing or a graphite composition packing ring with PTFE/composition packing) to electrically bond the shaft to the valve body for hazardous area service. For oxygen service applications, provide alternate shaft-to-valve body bonding according to the following step.

9. For oxygen service applications, attach the bonding strap assembly (key 131, figure 2) to the shaft with the clamp (key 130, figure 2), and connect the other end of the bonding strap assembly to the valve body with the cap screw (key 22). Secure each cap screw with a hex nut (key 30).

WARNING

Personal injury could result from packing leakage. Valve packing was tightened prior to shipment; however, the packing might require some readjustment to meet specific service conditions.

Valves with ENVIRO-SEAL packing systems will not require this initial re-adjustment. See ENVIRO-SEAL Packing System for Rotary Valves Instruction Manual (D101643X012) for packing instructions. If you wish to convert your present packing arrangement to ENVIRO-SEAL packing, refer to the retrofit kits listed in the parts kit sub-section near the end of this manual.

Maintenance

Valve body parts are subject to normal wear and must be inspected regularly and replaced as necessary. The frequency of inspection and replacement depends upon the severity of service conditions. Instructions are given in this section for: replacing packing; replacing disc, shaft, or bearing(s); changing disc rotation or valve action; and mounting and adjusting the actuator.

As used in these instructions, actuator refers to power actuators (such as pneumatic diaphragm, piston actuators, and rack and pinion actuators) or manual actuators (such as handwheel or handlever actuators).

WARNING

Avoid personal injury and property damage from sudden release of process pressure or bursting of parts. Before performing any maintenance operations:

D Do not remove the actuator from the valve while the valve is still pressurized.

D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations.

D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the

actuator cannot suddenly open or close the valve.

Instruction Manual

D251400X012

D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure

on both sides of the valve. Drain the process media from both sides of the valve.

D Vent the power actuator loading pressure and relieve any spring precompression.

D Uselock-outprocedurestobesurethattheabovemeasures s tay in effect while you work on the equipment.

D The valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the

pipeline. Process fluids may spray out from under pressure when removing the packing hardware or packing rings, or when loosening the packing box pipe plug.

D Check with your process or safety engineer for any additional measures that must be taken to protect against process

media.

8510B Valve (EMA)

November 2011

Packing Maintenance

Key numbers are referenced in figure 3 unless otherwise indicated. All maintenance operations in this section may be performed with the valve in the line. Packing may be PTFE V-ring or graphite.

An ENVIRO-SEAL packing system is also available with the 8510B control valve. To install the ENVIRO-SEAL packing system in an existing valve, follow the instructions in the instruction manual included with the packing system (D101643X012). To remove packing parts in a valve with the ENVIRO-SEAL packing system, follow the procedures for valves with the ENVIRO-SEAL packing system in this section. Install the replacement packing following the instructions in the packing system instruction manual (D101643X012).

Stopping Leakage

For valves with PTFE or graphite packing:

CAUTION

Tighten the packing flange only enough to prevent shaft leakage. Excessive tightening will only accelerate wear of the packing and could produce higher torques on the valve.

Leakage around the packing followers can be stopped by tightening the packing flange nuts (key 12, figure 8).

If the packing is relatively new and tight on the shaft, and if tightening the packing flange nuts does not stop leakage, the shaft may be worn or nicked so that a seal cannot be made. If the leakage comes from the outside diameter of the packing, the leakage may be caused by nicks or scratches around the packing box wall. Inspect the shaft and packing box wall for nicks and scratches when performing the packing replacement procedures.

For valves with the ENVIRO-SEAL packing system:

Optimum performance of the ENVIRO-SEAL packing system is obtained when the Belleville springs are tightened to their “target load.” The target load is the point where the springs are compressed to 85% of their maximum deflection, or nearly flat. Maximum deflection is when the springs are 100% compressed, or completely flat.

Under normal conditions, the packing nuts should not require re-tightening. However, when servicing, if the springs do not remain at the target load of 85% compression, retighten the packing box nuts according to the following procedure:

1. Tighten the packing flange nuts alternately and evenly, keeping the packing flange parallel with the valve flange (see figure 3), until the Belleville springs are compressed 100% (or completely flat).

8510B Valve (EMA)

November 2011

Instruction Manual

D251400X012

D For PTFE packing, loosen each packing flange nut one half turn (180_ of rotation).

D For Graphite packing, loosen each packing flange nut one quarter turn (90_ of rotation).

The target load of 85% compression has now been reached. If leakage continues, replace the packing components as described in the following procedures.

Replacing the Packing

For valves with PTFE or graphite packing:

This procedure may be performed without removing the actuator from the valve body if adding split PTFE/composition packing rings as a temporary measure on the actuator side of the valve body. However, the actuator must be removed from the valve body if replacing any other kind of packing on the actuator side of the valve body.

Key numbers in this procedure are shown in figure 8 unless otherwise indicated.

1. Isolate the control valve from the line pressure, release pressure from both sides of the valve body, and drain the process media from both sides of the valve. If using a power actuator, also shutoff all pressure lines to the power actuator, release all pressure from the actuator. Use lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.

2. Remove the packing flange nuts (key 12) and packing follower (key 15), plus the packing flange (key 9) if used, from thesideofthevalvebodyoppositetheactuator.

CAUTION

If removing the actuator in the following step, use a wheel puller to separate the actuator parts from the valve shaft. Do not drive the actuator parts off the valve shaft because this could move the valve bearings and disc away from the centered position, thereby damaging the disc and the valve body.

3. If necessary to remove the actuator, remove the cap screws and nuts (keys 22 and 30). Remove the clamp (key 130, figure 2) if the strap (key 131, figure 2) is used. If necessary, refer to separate actuator instruction manuals for assistance in removing the actuator.

4. Remove the packing flange nuts and pull out the packing follower (key 16), plus the packing flange (key 10) if used, fromtheactuatorsideofthevalvebody.

5. Remove the old packing rings (key 13) and, if used, the packing washers (key 27). Carefully avoid scratching the shaft or packing box wall to avoid damage that could cause leakage around the shaft. Clean all accessible metal parts and surfaces to remove particles that would prevent the packing from sealing.

Note

Except with oxygen service, lightly lubricate new PTFE V-rings with phenylmethyl silicone lubricant to aid in assembly.

Instruction Manual

D251400X012

WARNING

Do not lubricate parts when used in oxygen service, or where the lubrication is incompatible with the process media. Any use of lubricant can lead to the sudden explosion of media due to the oil/oxygen mixture, causing personal injury or property damage.

6. Use the appropriate procedures below for installing packing in either end of the valve.

D Install the packing washers (key 14), and packing rings (key 13). Make sure that PTFE/composition packing rings are

installed so that the ring splits do not line up to form a leak path.

D With graphite ribbon packing, stack the packing rings and packing washers together as shown in figure 3, and slide

the stack into the packing box as far as it will go while carefully avoiding trapping air among the rings.

D Install both packing followers and, if used, the packing flanges.

D Install the packing flange nuts, and tighten them only far enough to stop leakage under normal operating

conditions. For oxygen service applications, perform the next step.

D For oxygen service applications, attach the bonding strap assembly (key 131, figure 2) to the shaft with the clamp

(key 130, figure 2), and connect the other end of the bonding strap assembly to the valve body with a cap screw (key 22). Secure each cap screw with a hex nut (key 30).

7. Mount the actuator, if it was removed from the valve body, and adjust the actuator travel before returning the valve to service. This is necessary due to the measurements that must be made during the actuator adjustment process.

Refer to the Actuator Mounting section of this manual or to the separate actuator instruction manual for mounting and adjusting instructions before proceeding.

8. When placing the control valve into operation, check around the packing follower or leakage; retighten the packing flange nuts as required according to accepted bolting procedures.

For valves with ENVIRO-SEAL packing systems:

To replace the packing at the actuator side of the valve, the actuator must be removed. Also, the valve should be removed from the pipeline to allow proper readjustment of the disc position.

CAUTION

If removing the actuator, use a wheel puller to separate the actuator parts from the valve shaft. Do not drive the actuator parts off the valve shaft because this could move the valve bearings and disc away from the centered position, thereby damaging the disc and the valve body.

1. Isolate the control valve, and shut off all pressure lines to the power actuator. Release pressure from the valve body and actuator, and disconnect the pressure lines from the actuator if it will be removed from the valve body.

Instruction Manual

D251400X012

2. Loosen the two packing hex nuts evenly to remove spring tension, then remove the nuts.

3. Remove the packing flange and spring pack assembly. The spring pack assembly consists of the spring stack and packing follower. The spring stack is retained on the packing follower by an O-ring. Remove the anti-extrusion washer, the packing set, and the packing ring.

8510B Valve (EMA)

November 2011

CAUTION

The valve shaft surface condition is critical in making and maintaining a good seal. If the valve shaft surface is scratched, nicked, dented, or worn, replace the valve shaft before replacing the packing system.

4. Inspect the existing valve shaft. If necessary, replace the valve shaft as described in the procedures in this section.

5. Install the new packing system components as described in the ENVIRO-SEAL Packing System for Rotary Valves Instruction Manual (D101643X012).

6. Mount the actuator, if it was removed from the valve body, and adjust the actuator travel before returning the valve to service. This is necessary due to the measurements that must be made during the actuator adjustment process.

Refer to the Actuator Mounting section of this manual or to the separate actuator instruction manual for mounting and adjusting instructions.

Replacing the Seal Ring

Perform this procedure only if the control valve is not shutting off properly (that is, leaking downstream). This procedure does not require removing the actuator from the valve body.

Key numbers in this procedure are shown in figure 8 unless otherwise indicated.

1. Isolate the control valve from line pressure, and relieve pressure from the valve body. Shut off and disconnect all lines from the power actuator.

WARNING

The edges of a rotating disc have a shearing effect that may result in personal injury. To help prevent such injury, stay clear of the disc edges when rotating the disc (key 3).

CAUTION

Damage to the disc (key 3) may occur if the disc is not closed when the valve is being removed from the pipeline. If necessary, apply operating pressure to the actuator temporarily to retain the disc in the closed position while removing the valve from the pipeline.

2. Unscrew the flange bolts, and remove the valve from the pipeline.

3. Unscrew the machine screws (key 8), and remove the seal retainer (key 2) and the retainer clip (key 34).

4. Remove the seal ring or seal ring assembly (key 4). The spring (key 5) is removed with a PTFE seal ring.

5. For metal seal ring assemblies, replace the gaskets (key 4C) if the entire seal ring assembly is not replaced. Scrape off the old gaskets from both sides of the seal ring and the seal ring sides of the valve body (key 1) and seal retainer. Clean the gasket surfaces.

8510B Valve (EMA)

November 2011

6. Reconnect or mount the actuator (if it was removed) before proceeding.

For an actuator with adjustable travel, also adjust the actuator before proceeding. This is necessary due to the measurements that must be made during the actuator adjustment process.

Refer to the Actuator Mounting section of this manual and to the separate actuator instruction manual for mounting and adjusting instructions.

7. The valve should be closed during seal ring installation to permit accurate centering of the seal. To install the new seal ring:

D For a PTFE seal, if the spring (key 5) was disassembled, hook the spring ends together. Work the spring into the

recess in the seal ring (key 4). Install the seal ring and spring assembly into the recess in the valve body as shown in figure 8.

D For the metal seal ring assembly, install the seal ring assembly (key 4) as shown in figure 8.

Instruction Manual

D251400X012

CAUTION

New seal ring gaskets (key 4C) are very fragile and must be handled very carefully to avoid gasket kinking, cracking, or breakage that can cause leakage between the seal ring, seal retainer, and valve body. To avoid gasket damage, make sure that the valve body is lying flat so that the gaskets do not shift before the following step and step 8 are completed.

D For a metal seal ring on which the gaskets will be replaced, lay the following parts down in order so that they are

accurately centered on the valve body: one new gasket; thesealringorientedasshowninfigure8,andthesecond new gasket.

8. Attach the seal retainer (key 2) and the retainer clips (key 34) to the valve body and secure with the machine screws (key 8). Tighten the machine screws evenly so as not to crack or break the metal seal gaskets.

9. Be certain the disc is closed before installing the valve according to the Installation section of this instruction manual.

Replacing the Disc and Shaft Assembly or the Bearings

Perform this procedure to replace the valve disc, shaft, and taper key assembly if the disc does not rotate in response to rotation of the actuator end of the valve shaft. Key numbers in this procedure are shown in figure 8 unless otherwise indicated.

Disassembly

1. Remove the seal ring according to steps 1 through 5 of the Replacing Seal Ring section.

CAUTION

Use a wheel puller to separate actuator parts from the valve shaft. Driving the parts off the valve shaft could move the valve bearings and disc away from the centered position, damaging the disc and valve body.

2. Remove the cap screws (key 22) and hex nuts (key 30). Remove the clamp (key 130, figure 2) if the strap (key 131, figure 2) is used. Remove the actuator from the valve body (key 1) while referring to the separate actuator instruction manual for assistance.

3. Rotate the disc (key 3) to the fully open position.

4. Refer to figure 8 and determine the location of the smaller end of the taper key (key 21). Drive out the taper key towards the larger end.

5. Unscrew and remove the packing flange nuts (key 12), packing followers (keys 15 and 16), and packing flanges (keys 9 and 10) if used, from both sides of the valve body.

WARNING

Once the shaft has been removed in the following step, the disc may fall from the valve body. To avoid personal injury and disc damage, support the disc to prevent it from falling as the shaft is being removed.

6. Pulltheshaftoutthroughtheactuatorsideofthevalvebody.Iftheshaftcannotbepulledfree,carefullyuseapin punch to drive the shaft out from the side opposite the actuator. Do not damage the end of the shaft with the punch.

7. Remove the disc and spacers (key 7) from the valve body.

8. Remove the packing rings (key 13, figure 3), the packing washers (key 27, figure 3) if used, and the packing box rings (key 14, figure 3) from both sides of the valve body.

9. If either of the bearings (key 6) require maintenance or replacement, press them out, or remove them using a bearing puller. (See figure 4 for the puller dimensions.) For constructions with a metal bearing, also remove the bearing stop (key 25) with the bearing.

10. Clean the packing boxes andmetalpackingboxparts.

Assembly

Note

Before performing the following step, lubricate the outer bearing surfaces--except on oxygen service--with dry-film lubricant to facilitate future removal. Do not lubricate the insides of PTFE-lined bearings.

WARNING

Do not lubricate bearings that will be used for oxygen service, or where the lubrication is incompatible with the process media. Any injury or property damage.

1. If new bearings and, if used, bearing stops (key 25) are required, insert them through the packing boxes. Press the bearings in until the bearing end is flush with the valve body bore at one point and the remainder of the bearing end protrudes into the valve body bore. Or, use a bearing puller (see figure 4 for puller dimensions) to properly install and locate the new bearings and the bearing stops.

2. Install spacers (key 7) into the disc (key 3). The spacers fit loosely in the disc.

Note

If contaminating the process fluid with grease is a concern, do not apply grease according to the following step; especially if the thorough cleaning in step 7 cannot be performed.

use of lubricant can lead to the sudden explosion of media due to the oil/oxygen mixture, causing personal

3. Apply a small amount of heavy grease to the spacers. The grease will help to hold the spacers in place during the subsequent centering procedure.

D Valves with PTFE bearings use one PTFE coated spacer on each side of the disc. Install the spacer with the PTFE side

against the disc.

D Valves with metal bearings use two metal spacers on each side of the disc.

4. Insert the disc into the valve body. Be certain the taper key hole in the disc is on the actuator side of the valve body.

5. Slide the shaft through the valve body and disc.

6. Rotate the disc to the closed position. Measuring carefully, center the disc in the valve body bore. With the disc centered, use a feeler gauge to measure the clearance between each spacer and bearing. The clearance between each spacer and bearing should be equal and should be as close as possible to the value given in figure 5. If necessary, remove the disc and shaft, and reposition the bearings. Reinstall the disc and shaft, and repeat the centering and measuring process.

7. If the grease used to hold the spacers will contaminate the process fluid, disassemble the shaft and disc, remove the spacers, and clean the shaft, disc, valve body bore, and spacers thoroughly. Reinstall the disc and spacers into the valve body. Insert the shaft into the valve body and through the disc.

Actuator Mounting

With the valve body out of the line, mount the actuator on the valve body in accordance with the instructions in the actuator instruction manual. Mount the actuator yoke to the valve body, and tighten the actuator-mounting cap screws and nuts (keys 22 and 30) to the appropriate torque from table 7. The valve body might have an optional disc stop. Do not use the disc stop as a travel stop; use the actuator travel stop (if necessary, refer to the actuator instruction manual).

Key numbers in this procedure are shown in figure 8 unless otherwise indicated.

1. If using a power actuator, determine the actuator mounting style and position from figure 6.

If using a manual handwheel or handlever actuator, refer to the appropriate actuator instruction manual for mounting positions.

CAUTION

Rotating the disc (key 3) in the wrong direction will damage the seal ring (key 4). To avoid such damage, remove the seal ring according to the following step before mounting the actuator.

2. Mark the orientation of the seal ring with respect to the valve body so that the seal can be reinstalled in its original position. Remove the seal ring according to the procedure in the Replacing Seal Ring section of this instruction manual.

CAUTION

To prevent damage to the valve seal, due to the disc rotating past the fully closed position, use the following procedures:

D For actuators with an adjustable turnbuckle, such as the Fisher 1051, 1052, or 1061 actuator, the turnbuc kle must be

adjusted so that the valve is closed (determined by measuring as shown in figure 7) when the diaphragm plate or piston is against the actuator travel stop.

D For manually-operated actuators or actuators without adj ustable linkage, such as a Fisher 1066 or 1066SR actuator,

make certain the actuator travel stop prevents the disc from rotating past the fully closed position.

3. For actuators with an adjustable turnbuckle, adjust the turnbuckle to its minimum length to prevent damage. If necessary, refer to the appropriate actuator instruction manual for assistance with adjustment.

4. For power actuators, refer to figure 6 to locate the view of the mounting style and position to be used. When adjusting the actuator, be certain that the disc is rotated in the proper direction (clockwise to close when viewed from the actuator side of the valve) and that the disc is not rotated beyond the limits defined in the Installation section of this instruction manual.

5. For actuators with turnbuckles, adjust the turnbuckle to bring the disc to the fully closed position at the end of the actuator stroke. Refer to the appropriate actuator instruction manual for assistance.

6. To determine the fully closed disc position (zero degrees of disc rotation), measure the distances between the disc face and the retaining ring face (or from a line from the top to the bottom of the valve body) at the top and bottom of the valve as shown in figure 7. When necessary, adjust the actuator to rotate the disc slightly until the two measurements are equal.

7. Reinstall the seal ring according to the procedure in the Replacing Seal Ring section.
