Introduction

Scope of Manual

This instruction manual includes installation,

maintenance, and parts information for 0.5 through

4-inch Design RSS lined globe valves. Refer to

separate manuals for instructions covering the

actuator, positioner, 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, and is well-suited for pure

media applications, as well. The Design RSS valve

body provides an economical alternative to alloy

valve bodies in a wide variety of applications.

No person may install, operate, or maintain a Design

RSS valve without first 

D

 being fully trained and

qualified in valve, actuator and accessory

installation, operation and maintenance, and 

D

 carefully reading and understanding the contents

of this manual. If you have any questions concerning

these instructions, contact your Fisher sales office

before proceeding.

and Type 3582 Positioner

Specifications

Specifications for the Design RSS valve are shown

in table 1. If the valve is shipped with the actuator,

some of the valve specifications are on the valve

nameplate, which is attached to the actuator. If the

valve is shipped without the actuator, the valve

nameplate is wired to the valve.

Neither Emerson, Emerson Process

Management, nor Fisher  assume

responsibility for the selection, use, or

maintenance of any product.

Responsibility for proper selection,

use, and maintenance of any Fisher

product remains solely with the

purchaser and end-user.
