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 sliding‐stem valves with 9.5, 12.7, 19.1, 25.4, and 31.8 mm
(3/8, 1/2, 3/4, 1, and 1‐1/4 inch) diameter stems. The system can be used with many sliding‐stem valves as shown in
the Applications section of the Specifications. 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 KALREZ packing systems 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
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 KVSP Fire‐Safe Series uses Vespel CR‐6100 backup rings, KALREZ seal rings, and a die‐formed flexible
graphite ring located on top of the KALREZ packing set.
These packing systems help seal your process to conserve valuable fluids, and help protect the environment against
the emission of toxic or polluting liquids and gases. The external live‐loading provides a constant load over the life of
the packing material, which reduces your need for packing box adjustment and maintenance.
If the piping and valve are insulated, do not allow insulation to extend above the yoke boss surface, covering the
KALREZ packing arrangement. Keep the KALREZ packing arrangement exposed to ambient air conditions.
