Installation

Key numbers in this procedure are shown in figures 13, 14, and 15 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 4 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 on page 10 in this manual.

Instruction Manual

D104016X012

8590 Valve

January 2019

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 limited in their pressure drop and temperature range capabilities, do not apply any other conditions to the valve without first contacting your Emerson sales office

The maximum allowable inlet pressures for steel and stainless steel valve bodies are consistent with the pressure‐temperature ratings shown in table 1, except where further limited by the trim and packing material temperature capabilities given in table 4. Valves are also available in CW2M valve body materials. The CW2M valve body material is not listed in ASME B16.34. Valve bodies constructed of this material mates with ASME flanges, but must not be installed in systems requiring conformance to ASME standards if not included in ASME pressure/temperature ratings. Maximum allowable inlet pressures for 8590 valve bodies made of CW2M construction materials are shown 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 it is free of foreign material.

3. The valve is normally shipped as part of a control valve assembly, with an 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 to close the valve 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 section on page 22 of this manual and to the separate actuator instruction manual for mounting and adjusting instructions before proceeding.

4. Inspect adjacent pipelines to be certain they 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 disk (key 6) will occur if any pipe flanges or piping connected to the valve body interfere with the disk rotation path. However, the disk 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 EN pipe sizes. If piping with a smaller inner diameter than specified above is connected to the valve, measure carefully to be certain the disk rotates without interference before putting the valve into operation.

5. Flow is in the standard direction when the seal retainer (key 16) is facing downstream. Standard flow direction is also indicated by the flow direction arrow cast into the valve body. Flow in the forward direction is permissible within allowable pressure drop limits with the proper seal.

CAUTION

8590 disk rotation is counterclockwise to open (when viewed from the actuator side of the valve body, see figure 12) through 90 degrees of disk rotation.

6. With the disk 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.

D104016X012

Lifting Guidelines

Threaded holes for lifting are standard on the NPS 3 - 24 valve bodies. It is required that swivel hoists rings be used to lift the valve or valve and actuator assembly. An eyebolt cannot accommodate all lifting angles required to install or maintain the valve. The load carrying capability of an eyebolt decreases dramatically if used in any other orientation than axially. Therefore, the use of eyebolts is not permitted.

CAUTION

Care must be taken when lifting the valve/actuator assembly to ensure the accessories and tubing are not damaged in the process. The valve weight is listed in table 2. For the actuator weight, refer to the appropriate instruction manual. Make sure to use appropriate lifting straps/hoists capable of lifting this combined weight.

WARNING

Avoid personal injury or property damage caused by uncontrolled movement or dropping of the valve assembly. Ensure the disk is secure from rotating during lifting process. Failure to do so could result in personal injury if the disk

rotates uncontrolled during lifting. Swivel Hoist rings are sized to lift only the valve and actuator. Do not attach piping or other structures to the valve and

actuator assembly when lifting with swivel hoists rings. Take appropriate precautions to avoid unbalanced loading which may result in sudden swinging or movement of the

assembled unit, including additional lifting and/or support methods when necessary. Do not use eyebolts when lifting the valve or valve and actuator assembly due to variable loading angles inherent to valve

maintenance and installation. Failure to utilize safe lifting practices may result in equipment damage and/or personal injury.

Lifting Valve/Actuator Assembly

To lift the assembly, install swivel hoist rings into one or two of the threaded holes on the valve body (see figure 3. Thread sizes are listed in table 5. When lifting the valve and actuator assembly, a strap around the actuator may be required to ensure lifting stability. If straps are used on the actuator, ensure the lifting location is above the center of gravity (CG) for the actuator to prevent load shifting during lifting. Refer to the appropriate assembly drawings for the CG for your assembly.

Lifting Valve Only

To lift the valve, insert two swivel hoist rings into the body. Thread sizes are listed in table 5. Ensure the valve is closed and that the packing is tightened to prevent shaft rotation during lifting. Without an actuator, the valve disk is free to rotate if enough momentum is generated during the lifting process by a sudden stop. The packing and seal friction should prevent the disk from rotating; however take proper precaution when lifting the valve.

7. Insert the valve between the flanges and install two or more line flange studs into the line flanges to help hold the valve in position while centering the valve. Carefully center the valve on the flanges to ensure disk clearance.

Note

Lubricate line flange studs before inserting them into flanges. If necessary, provide additional support for the control valve assembly because of its combined weight.

WARNING

For lugged valve bodies with threaded line bolt holes, personal injury and property damage could result from sudden release of process pressure if line bolts are not properly installed. To ensure proper line bolt thread engagement, line studs must be centered in the threaded section of the valve body so that each stud has equal thread engagement in the body. See figure 5.

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

WARNING

An 8590 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 the valve body is grounded to the pipeline before putting the control valve assembly into operation in a flammable or hazardous atmosphere.
