Scope of Manual

This instruction manual includes installation, mainte-
nance, and parts information for 1/2- through 4-inch
Design RSS lined globe valves. Refer to separate
manuals for instructions covering the actuator, posi-
tioner, and accessories.

Description

The Design 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. The Design RSS valve body provides
an economical alternative to alloy valve bodies in a
wide variety of applications.
