Introduction
Scope of Manual
This instruction manual includes installation, maintenance, and parts information for KALREZ valve stem packing
(KVSP) systems. These systems are available for Fisher rotary valves with 12.7 through 38.1 mm (1/2 through 1‐1/2
inch) shaft diameters. The system can be used with many rotary valves, as shown in table 1. Refer to appropriate valve
and actuator instruction manuals for necessary information relating to the disassembly and assembly of the valve and
actuator.
Do not install, operate, or maintain a KALREZ packing system 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
See table 1 for valve designs and shaft diameters where KALREZ packing systems can be applied.
Emerson Process Management offers KALREZ packing systems that you can easily install into your existing valves or
that you can purchase with new valves. The KVSP 500 Series uses Vespelr CR‐6100 backup rings and KALREZ seal
rings.
The external live‐loading provides a constant load over the life of the packing material, which reduces the need for
packing box adjustment and maintenance.
Installation
Use these instructions to install KALREZ packing in valves that have standard packing, or when inspecting or replacing
KALREZ packing.
Table 2 lists part numbers for KALREZ packing sets only. When retrofitting valves to KALREZ packing, contact your
Emerson Process Management sales office for information on additional parts needed.
