Installation

WARNING

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

Personal injury or equipment damage caused by sudden release of pressure may 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 over‐pressure 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.

WARNING

When ordered, the valve configuration and construction materials were selected to meet particular pressure, temperature, pressure drop, and controlled fluid conditions. Because some valve 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

WARNING

Some bonnet flanges have a tapped hole that was used to handle the bonnet during manufacture. Do not use this tapped hole to lift the valve assembly or personal injury may result.

1. Before installing the valve, inspect the valve and associated equipment for any damage and any foreign material.

2. Make certain the valve body interior is clean, that pipelines are free of foreign material, and the valve is oriented so

that pipeline flow is in the same direction as the arrow on the side of the valve.

Note

NPS 8 to 12 CL900 and CL1500 HPT-C valves contain a flow vane in the lower flow passage. This is critical to proper function of the valve and is not a defect.

3. Gas Service: The normal method of mounting for gas service is with the actuator vertical above the valve body.

However, the control valve assembly may be installed in any orientation unless limited by seismic criteria. Other positions may result in uneven valve plug and cage wear that could result in improper operation. For mounting assistance, consult your Emerson sales office

CAUTION

To avoid possible damage to the packing, do not allow the installed actuator angle to be so flat as to allow liquid inside the bonnet to come in contact with the packing.

Also, if insulation is applied, do not let the insulation run up the extension bonnet. This could cause the packing to freeze and be damaged.

Instruction Manual

D104208X012

HPS-C and HPT-C Valves

September 2020

Liquid Service: The preferred method of mounting for liquid service is with the actuator vertical above the valve body. This will allow a vapor layer to form between the liquid and the packing. If there are piping constraints, the actuator can be angled slightly from vertical. However, in no case should the angle be so flat as to allow liquid inside the bonnet to come in contact with the packing. For mounting assistance, consult your Emerson sales office.

4. If insulation is applied, make sure it is applied only to the body/bonnet joint. Do not let the insulation run up the

extension bonnet.

5. Use accepted piping and welding practices when installing the valve in the line. For flanged valve bodies, use a

suitable gasket between the valve body and pipeline flanges.

6. If the actuator and valve are shipped separately, refer to the actuator mounting procedure in the appropriate

actuator instruction manual.

7. If the valve body was shipped without packing installed in the packing box, install the packing before putting the

valve body into service. Refer to instructions given in the Packing Maintenance procedure.

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.

Valves with ENVIRO‐SEAL™ live‐loaded packing will not require this initial readjustment. See the Fisher instruction manual ENVIRO‐SEAL Packing System for Sliding‐Stem Valves (D101642X012 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.

) for packing instructions. If you wish to

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 packing maintenance and trim maintenance. 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. 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.

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 pneumatic 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.

Instruction Manual

D104208X012

CAUTION

Follow instructions carefully to avoid damaging the product surfaces, which could result in damage to the product.

Note

The HPS-C/HPT-C valves use spiral-wound gaskets which are crushed to provide their seal. A spiral-wound gasket should never be reused. Whenever a gasket seal is disturbed by removing or shifting parts, a new gasket should be installed upon reassembly. This is necessary to ensure a good gasket seal because the used gasket may not seal properly.

Packing Maintenance

This section covers PTFE V‐ring, double PTFE, and graphite packing used in extension bonnets (figure 2).

Note

If the valve has ENVIRO‐SEAL live‐loaded packing installed, refer to the instruction manual ENVIRO‐SEAL Packing System for Sliding Stem Valves (D101642X012

) for packing instructions. Figure 4 shows typical ENVIRO‐SEAL arrangements.

Standard packing key numbers are shown in figure 2. ENVIRO-SEAL packing key numbers are shown in figure 4. Bonnet and valve key numbers are shown in figures 5, 6, and 7.

For spring-loaded single PTFE V-ring packing, the spring (key 24) maintains a sealing force on the packing. If leakage is noted around the packing follower (key 28), check to be sure the shoulder on the packing follower is touching the bonnet. If the shoulder is not touching the bonnet, tighten the packing flange nuts (key 20), until the shoulder is against the bonnet. If leakage cannot be stopped in this manner, proceed with replacing packing procedures.

If there is undesirable packing leakage with other than spring‐loaded packing, first try to limit the leakage and establish a stem seal by tightening the packing flange nuts.

If the packing is relatively new and tight on the stem, and if tightening the packing flange nuts does not stop the leakage, it is possible that the valve stem is worn or nicked so that a seal cannot be made. The surface finish of a new valve stem is critical for making a good packing seal. If the leakage comes from the outside diameter of the packing, it is possible that the leakage is caused by nicks or scratches around the packing box wall. If performing any of the following procedures, inspect the valve stem and packing box wall for nicks and scratches. If leakage continues, replace the packing by following the numbered steps presented in the replacing packing procedure.

Adding Packing Rings

Key numbers referred to in this procedure are shown in figures 2, 5, and 6 unless otherwise noted.

When using packing with a lantern ring (key 24) it may be possible to add packing rings above the lantern ring as a temporary measure without removing the actuator from the valve body.

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 shut‐off 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 20) and lift the packing flange, upper wiper, and packing follower (keys 18, 27,

and 28) away from the valve body.

3. It may be possible to dig out the old packing rings on top of the lantern ring, but use care to avoid scratching the

valve plug stem or packing box wall. Clean all metal parts to remove particles that would prevent the packing from sealing.

4. Remove the stem connector and slip the packing rings over the end of the valve plug stem.

5. Reassemble the packing follower, upper wiper, packing flange, and packing flange nuts (keys 28, 27, 18, and 20).

6. Reconnect the body‐actuator stem connection according to the appropriate actuator instruction manual.

7. Tighten the packing flange nuts only far enough to stop leakage under operating conditions. Check for leakage

around the packing follower when the valve is being put into service. Retighten the packing flange nuts as required (see table 3).

Replacing Packing

WARNING

Refer to the warning at the beginning of the Maintenance section in this instruction manual.

Key numbers and sequence of assembly of packing parts are shown in figure 2. Bonnet and valve key number locations are shown in figures 5, 6, and 7, unless otherwise noted.

1. Isolate the control valve from the line pressure, release pressure from both sides of the valve body, and drain the

2. Disconnect the operating lines from the actuator and any leak-off piping from the bonnet. Disconnect the stem

connector and remove the actuator from the valve by unscrewing the yoke locknut (key 32) or hex nuts (key 30).

3. Loosen the packing flange nuts (key 20) so that the packing is not tight on the valve stem. Remove any travel

indicator parts and stem locknuts from the valve stem threads.

WARNING

To avoid personal injury or property damage caused by uncontrolled movement of the bonnet, loosen the bonnet by following the instructions in the next steps.

Do not remove a stuck bonnet by pulling on it with equipment that can stretch or store energy in any other manner. The sudden release of stored energy can cause uncontrolled movement of the bonnet. If the cage sticks to the bonnet, proceed carefully with bonnet removal and support the cage so that it will not fall unexpectedly from the bonnet.

4. When lifting the bonnet, be sure the plug and stem assembly (key 4 and 5), cage (key 2), and cage retainer (key 45),

if applicable, remain in the valve body. This avoids damage to the seating surfaces as a result of the assembly dropping from the bonnet after being lifted part way out. The parts are also easier to handle separately.

WARNING

To avoid possible personal injury, review your process shutdown procedures to be sure process pressure is not applied to the valve for the following procedure.

5. Hex nuts (key 13) attach the bonnet to the valve body (key 1). Loosen these nuts or cap screws approximately 3 mm

(1/8 inch). Then, loosen the body-to-bonnet joint by either rocking the bonnet or prying between the bonnet and valve body. Work with a prying tool around the bonnet until the bonnet loosens.

D If fluid leaks from the joint, it may indicate that process pressure is applied to the valve. Review your process

shutdown procedures, and be sure process pressure is not applied to the valve.

D If no fluid leaks from the joint, proceed to the next step.

6. Unscrew the hex nuts (key 13) and carefully lift the bonnet off the valve stem. If the valve plug and stem assembly

starts to lift with the bonnet, use a brass or lead hammer on the end of the stem and tap it back down. Set the bonnet on a cardboard or wooden surface to prevent damage to the bonnet gasket surface.
