Description

The YD and YS valves are three‐way valves for throttling or on‐off (flow switching) service with converging (flow mixing) or diverging (flow splitting) flow patterns. YS valves, when used in diverging service, are recommended for on‐off applications only. These valves are generally shipped as part of a control valve assembly, having a diaphragm, piston, or manual actuator mounted on them. A typical construction is shown in figure 1.

Specifications

Specifications for the YD and YS valves are shown in table 1. Some specifications appear on the actuator nameplate if the valve is part of a complete control valve assembly.

Installation

WARNING

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

Personal injury or equipment damage caused by sudden release of pressure might result if the valve assembly is installed where service conditions could exceed the limits given in table 1 or on the appropriate nameplates. To avoid such injury or damage, provide a relief valve for overpressure protection as required by government or accepted industry codes and good engineering practices.

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

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

CAUTION

When ordered, the valve configuration and construction materials were selected to meet particular pressure, temperature, pressure drop, and controlled fluid conditions. Responsibility for the safety of process media and compatibility of valve materials with process media rests solely with the purchaser and end‐user. Since some body/trim material combinations are limited in their pressure drop and temperature ranges, do not apply any other conditions to the valve without first contacting your Emerson sales office

Before installing the valve, inspect the valve and pipelines for any damage and any foreign material which may cause product damage.

or Local Business Partner.

1. Before installing the valve, inspect it for any shipping damage and for any foreign material in the valve body cavity.

2. Clean out all pipelines to remove pipe scale, chips, welding slag, and other foreign materials.

3. Use accepted piping and welding practices when installing the valve. For flanged valves, use suitable gaskets between the valve and the pipeline flanges.

4. Do not install the valve in a system where the working pressures exceed those specified in the ASME pressure/temperature ratings or those specified by Emerson Automation Solutions.

5. If continuous operation is required during maintenance and inspection, install a conventional three‐valve bypass around the valve so that the valve can be isolated.

6. Orient the valve so that flow will be in the direction indicated by the flow arrows.

Note

The common port for the YD is the bottom port as shown on the flow direction plates (key 17) in figure 10. The common port for the YS is the left‐hand port as shown on the flow direction plates in figure 9.

CAUTION

Depending on valve body materials used, post weld heat treating may be required. If so, damage to internal elastomeric and plastic parts, as well as internal metal parts is possible. Threaded connections may also loosen. In general, if post weld

Page 4

YD and YS Valves

July 2017

heat treating is to be performed, all trim parts should be removed. Contact your Emerson sales office or Local Business Partner for additional information.

Instruction Manual

D100425X012

7. YD or YS control valves can be installed in any position, although the recommended position is with the actuator vertical above the valve. For NPS 4 and 6 YS valves, size 80 or larger actuators mounted between 45 degrees above and 45 degrees below horizontal should be supported. If forces other than normal gravitational forces are experienced, such as vibrational forces, smaller size actuators might also need to be supported when they are not in a vertical position. For further information, consult your Emerson sales office or Local Business Partner.

WARNING

Personal injury could result from packing leakage. Valve packing was tightened before shipment; however, the packing might require some readjustment to meet specific service conditions. Check with your process or safety engineer for any additional measures that must be taken to protect against process media.

Valves with ENVIRO‐SEAL live‐loaded packing or HIGH‐SEAL live‐loaded packing will not require this initial re‐adjustment. See the Fisher instruction manuals titled ENVIRO‐SEAL Packing System for Sliding‐Stem Valves or HIGH‐SEAL Live‐Loaded Packing System (as appropriate) 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 subsection near the end of this manual.

Maintenance

Valve parts are subject to normal wear and must be inspected and replaced as necessary. Inspection and maintenance frequency depends on the severity of service conditions. This section includes instructions for trim maintenance, packing maintenance, and ENVIRO‐SEAL bellows seal bonnet replacement. All maintenance operations may be performed with the valve in the line.

WARNING

Avoid personal injury or property damage from sudden release of process pressure or uncontrolled movement 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 to avoid personal

injury.

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.

Page 5

Instruction Manual

D100425X012

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

from 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 actuator spring precompression.

D Use lock‐out procedures to be sure that the above measures stay 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 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.

Note

ENVIRO‐SEAL and HIGH‐SEAL packing do not require lubrication.

LUBRICATOR

LUBRICATOR/ISOLATING VALVE

WARNING

To avoid personal injury or property damage resulting from fire or explosion, do not lubricate packing used in oxygen service or in processes with temperatures over 260_C (500_F).

If a lubricator or lubricator/isolating valve (figure 2) is provided for PTFE/composition or other packings that require lubrication, it will be installed in place of the pipe plug (key 14, figure 13). Use a good quality silicon‐base lubricant. Do not lubricate packing used in oxygen service or in processes with temperatures over 260_C (500_F). To operate the lubricator, simply turn the cap screw clockwise to force the lubricant into the packing box. The lubricator/isolating valve operates the same way except open the isolating valve before turning the cap screw and then close the isolating valve after lubrication is completed.

GRAPHITE TYPE PACKING PTFE TYPE PACKING

The following procedure covers PTFE V‐ring packing. A similar procedure can be followed for PTFE/composition packing. However, because PTFE/composition packing comes in split rings, it is possible to replace the rings without removing the actuator from the valve.

Installation of graphite ribbon/filament packing requires special care to avoid trapping air between the rings. Start only one ring at a time without forcing the top of the packing ring below the bottom of the entrance chamfer of the packing box. Thus, when a ring is added, the stack should not be pushed into the cavity more than the thickness of the added ring.

The arrangement of packing box parts is shown in figures 3, 4, 5, 6, and 7. Key numbers used in the following steps are shown in figures 13 and 14.

Page 7

Instruction Manual

D100425X012

1. Remove the actuator and bonnet according to steps 1 through 4 of the Disassembly procedure in the Maintenance section on page 7.

2. With the stem and valve plug assembly removed from the bonnet, remove the packing nuts (key 5), packing flange (key 3), wiper ring (key 12), and packing follower (key 13) from the bonnet. The old packing can then be pulled out with a packing hook (take care to avoid scratching the packing box wall) or pushed out using a rod inserted through the bottom of the bonnet.

3. Clean the packing box and all metal parts.

4. Complete maintenance necessary on other parts and install the bonnet on the valve as indicated in the Assembly section (starting on page 12).

5. Install the new packing and associated parts in the sequence shown in figures 3, 4, 5, 6, and 7. Be careful not to damage the packing during installation.

6. Replace the packing flange and packing flange nuts.

For spring‐loaded PTFE V‐ring packing, tighten the packing flange nuts until the shoulder on the packing follower contacts the bonnet.

For graphite packing, tighten the packing flange nuts to the maximum recommended torque shown in table 3. Then, loosen the packing flange nuts, and retighten them to the recommended minimum torque shown in table 3.

For other packing types, tighten the packing flange nuts alternately in small equal increments until one of the nuts reaches the minimum recommended torque shown in table 3. Then, tighten the remaining flange nut until the packing flange is level and at a 90‐degree angle to the valve stem.

YD and YS Valves

For ENVIRO‐SEAL or HIGH‐SEAL live‐loaded packing, refer to the note at the beginning of the Packing Maintenance section.

7. Mount the actuator on the bonnet and make up the stem connection according to the procedure given in the appropriate actuator instruction manual.

Trim Maintenance

WARNING

Observe the warning at the start of the Maintenance section.

CAUTION

To avoid damaging parts, do not grip the bellows shroud or other parts of the stem/bellows assembly. Grip only the flat areas on the stem where it extends out of the top of the bellows shroud.

Key numbers in the following procedures are shown in figure 10 for standard YD, in figure 11 for high‐temperature YD, and in figure 9 for YS, except where indicated.

Disassembly

1. Isolate the control valve from the line pressure, release pressure from both sides of the valve, and drain the process media from both sides of the valve. Remove actuator supply pressure, and use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.

3. Remove the nuts (key 16, figures 9 and 10) or cap screws from the bonnet flange.

4. Lift off the bonnet along with the valve plug and stem (keys 2 and 5, figures 9 and 10). Due to the design of the valve, several other trim parts will be drawn out with the valve plug. They are as follows:

YD (Standard)‐‐The upper cage (key 3A) and associated seals, gaskets, and shim (keys 9, 11, 19, 20A, 20B, and 22).

YD (High Temperature)‐‐The upper cage (key 3B) and associated gaskets and shim (keys 9, 11, and 22).

YS‐‐The upper seat (key 7), upper cage (key 3), and associated gaskets and shim (keys 9, 11, and 22).

CAUTION

The exposed portion of the cage provides a guiding surface that must not be damaged during disassembly or maintenance. Damage could affect valve performance. If the cage is stuck in the valve, use a rubber mallet to strike the exposed portion at several points around the circumference.

6. To replace the adaptor (key 24, figure 15) on ENVIRO‐SEAL bellows seal bonnets, place the plug stem assembly and valve plug in a soft‐jaw chuck or other type of vise so that the jaws grip a portion of the valve plug that is not a seating surface. Drive out the pin (key 36, figure 15). Reverse the plug stem assembly in the soft‐jaw chuck or vise. Grip the flat areas on the valve stem just below the threads for the actuator/stem connection. Unscrew the valve plug/adaptor assembly (key 24, figure 15) from the valve stem assembly (key 20, figure 15).

Instruction Manual

D100425X012

CAUTION

Never use an old stem with a new valve plug. The use of an old stem requires drilling a new pin hole through the stem (or adaptor, in case an ENVIRO‐SEAL bellows seal bonnet is being used). This drilling weakens the stem or adaptor and may cause failure in service. However, a used valve plug may be reused with a new stem or adaptor.

7. The internal parts of the bonnet can now be disassembled, if necessary. For packing replacement, refer to the section entitled Packing Replacement on page 6.

8. Standard YD Only—It is recommended that the cage seal (key 19), seal ring (key 20A), and backup ring (key 20B) be replaced upon assembly. These can be removed by prying them out of the upper cage grooves with a screwdriver or a soft‐tipped instrument. If a screwdriver is used, take care not to scratch the surfaces of the cage.

9. The remaining trim parts can now be lifted out of the valve. Under severe service conditions, some of these parts might have become stuck to the valve. In this case, it might be necessary to use a seat ring puller to remove these parts. Because there is a slight clearance around the outer circumference of the lower cage (key 4) and seat ring (key 8), it might be possible to remove these by tapping them loose, if interior room permits.
