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 certain 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

3

	1. For hot water or steam service, limit maximum temperature to 207_C (405_F).
	2. Reinforced PTFE in phenolic resin. Emerson Process Management designation is FMS 30B4.
	3. PTFE with selected fillers. Emerson Process Management designation is FMS 30B5.
	4. For temperature limits of ENVIRO-SEAL packing systems, see the instruction manual Fisher ENVIRO-SEAL Packing System for Rotary Valves (D101643X012).
	5. These materials are only available in the splined shaft version of 8510B, and not in the double D end connection with anti-blowout shaft.

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

4

Instruction Manual	8510B Valve (EMA)
D251400X012	November 2011

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 the 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 install 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.

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.

DDisconnect 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.

6

Instruction Manual	8510B Valve (EMA)
D251400X012	November 2011

DUse 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 Use lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.

DThe 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.

DCheck with your process or safety engineer for any additional measures that must be taken to protect against process media.

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).

7

8510B Valve (EMA)	Instruction Manual
November 2011	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 the side of the valve body opposite the actuator.

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, from the actuator side of the valve body.

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.
