Introduction

The product covered in this document is no longer in production. This document, which includes the latest published
version of the instruction manual, is made available to provide updates of newer safety procedures. Be sure to follow
the safety procedures in this supplement as well as the specific instructions in the included instruction manual.

For more than 30 years, Fisher products have been manufactured with asbestos‐free components. The included
manual might mention asbestos containing parts. Since 1988, any gasket or packing which may have contained some
asbestos, has been replaced by a suitable non‐asbestos material. Replacement parts in other materials are available
from your sales office.

Instruction Manual

D104338X012

Specifications

This product was intended for a specific range of service conditions‐‐pressure, pressure drop, process and ambient
temperature, temperature variations, process fluid, and possibly other specifications. Do not expose the product to
service conditions or variables other than those for which the product was intended. If you are not sure what these
conditions or variables are, contact your Emerson sales office
other pertinent information that you have available.

for assistance. Provide the product serial number and all

Inspection and Maintenance Schedules

All products must be inspected periodically and maintained as needed. The schedule for inspection can only be
determined based on the severity of your service conditions. Your installation might also be subject to inspection
schedules set by applicable governmental codes and regulations, industry standards, company standards, or plant
standards.

In order to avoid increasing dust explosion risk, periodically clean dust deposits from all equipment.

When equipment is installed in a hazardous area location (potentially explosive atmosphere), prevent sparks by proper
tool selection and avoiding other types of impact energy.

Parts Ordering

Whenever ordering parts for older products, always specify the serial number of the product and provide all other
pertinent information that you can, such as product size, part material, age of the product, and general service
conditions. If you have modified the product since it was originally purchased, include that information with your
request.

WARNING

Use only genuine Fisher replacement parts. Components that are not supplied by Emerson should not, under any
circumstances, be used in any Fisher product, because they may void your warranty, might adversely affect the
performance of the product, and could cause personal injury and property damage.

Installation

WARNING

D Personal injury or equipment damage caused by sudden release of pressure or bursting of parts may result if the valve

assembly is installed where service conditions could exceed the limits given in the applicable product literature, the
limits on the appropriate nameplates, or the mating pipe flange rating. Use pressure‐relieving devices as required by
government or relevant industry codes and good engineering practices. If you cannot determine the ratings and limits
for this product, contact your Emerson sales office

D To avoid personal injury, always wear protective gloves, clothing, and eyewear when performing any installation

operations.

D To avoid personal injury or property damage, use proper lifting and rigging practices while lifting, installing or

removing the valve assembly. Be sure to use lifting and rigging equipment properly sized and selected for the weight
and configuration of the valve assembly or component being lifted.

D Personal injury could result from packing leakage. Valve packing was tightened before shipment; however, the packing

might require some readjustment to meet specific service conditions.

D Many rotary shaft valves are not necessarily grounded to the pipeline when installed in a flammable, hazardous, oxygen

service, or explosive atmospheres. An explosion is possible, due to the discharge of static electricity from the valve
components. To avoid personal injury or property damage, make sure that the valve is grounded to the pipeline before
placing the control valve assembly into service. Use and maintain alternate shaft‐to‐body bonding, such as a
shaft‐to‐body bonding strap assembly.

D Rotary shaft valves are designed and intended for installation between flanges. Personal injury or property damage may

result from improper installation. To avoid personal injury or property damage caused by the sudden release of
pressure or bursting of parts, do not use or install rotary shaft valves (including single lug constructions) for dead‐end
service.

D Check with your process or safety engineer for any additional measures that must be taken to protect against process

media.

D If installing into an existing application, also refer to the WARNING in the Maintenance section.

D When ordered, the valve configuration and construction materials were selected to meet particular pressure,

temperature, pressure drop, and controlled fluid conditions. Responsibility for the safety of process media and
compatibility of valve materials with process media rests solely with the purchaser and end‐user. To avoid possible
personal injury and because some valve/trim material combinations are limited in their pressure drop and temperature
ranges, do not apply any other conditions to the valve without first contacting your Emerson sales office.

before proceeding.

CAUTION

D Ensure that the valve and adjacent pipelines are free of foreign material that could damage the valve seating surfaces.
