Scope of Manual

This instruction manual provides installation, maintenance, and parts information for the HVP Series control valve.

Do not install, operate, or maintain HVP control valves without being fully trained and qualified in valve, actuator, and
accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important to
carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If you
have any questions about these instructions, contact your Emerson Process Management sales office before
proceeding.

Description

The HVP (high viscous polymer) Series control valve is used extensively by the polymer industry. These processes
generally require the valves to operate at and maintain high temperatures to assure that the polymer fluid flows freely.
The HVP Series can provide integral valve body passages through which a heat-transfer fluid is pumped to keep the
valve and process fluid heated.

Forged and fabricated valve body styles are engineered to meet your process and piping requirements. Standard valve
body and trim designs can be adapted to exactly match specifications. Models include: HVP-TS (figure 1) for throttling
service; HVP-DS (figure 2) for diverting service (three-way valve); and HVP-SS for stop service (on/off).

Specifications

Table 1 lists specifications for the HVP control valve. Some of the specifications for a given control valve as it originally
comes from the factory are stamped on a nameplate located on the actuator spring barrel.

Installation

WARNING

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

Personal injury or system 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 and on the appropriate nameplates. To avoid such injury or
damage, use pressure-relieving devices as required by applicable industry codes to prevent the service conditions from
exceeding these limits.

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 Process Management sales office.

1. Use accepted piping and welding practices when installing the valve in the line. For welding end valve bodies,

completely disassemble the valve removing all trim parts before welding the valve body in the line. For flanged
valvebodies,usesuitablegasketsbetweenthevalvebodyflangesandpipelineflanges.

Note

Depending on valve body materials used, post-w eld heat treating might be needed. Post-weld heat treatment can damage
internal elastomeric, plastic, and metal parts. Shrunk-fit pieces and threaded connections might loosen. In general, if post-weld
heat treating is needed, remove all trim parts. Contact your Emerson Process Management sales office for additional information.

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

actuator instruction manual.

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

into service.
