Introduction
Scope of Manual
This instruction manual includes installation, maintenance, and parts information for NPS 1 through NPS 4 Fisher RSS
lined globe valves. Refer to separate manuals for instructions covering the actuator, positioner, and accessories.
Description
The RSS lined globe‐style valve (figure 1) has pure‐modified PTFE trim parts, push‐down‐to‐ close action, and positive
shutoff. This valve is intended for applications involving severely corrosive and toxic flowing media, and is well‐suited
for pure media applications, as well. The RSS valve body provides an economical alternative to alloy valve bodies in a
wide variety of applications.
Do not install, operate, or maintain an RSS valve 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 sales office
or Local Business Partner before
proceeding.
