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 Automation Solutions sales office for assistance. Provide the product
serial number and all other pertinent information that you have available.
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. Control Valve surface temperature is dependent upon
process operating conditions.
WARNING
Control valve surface temperature is dependent upon process operating conditions. Personal injury or property damage,
caused by fire or explosion, can result if the valve body surface temperature exceeds the acceptable temperature for the
hazardous area classification. To avoid an increase of instrumentation and/or accessory surface temperature due to process
operating conditions, ensure adequate ventilation, shielding, or insulation of control valve components installed in a
potentially hazardous or explosive atmosphere.
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 Automation Solutions 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 Automation Solutions sales office before proceeding.
D To avoid personal injury, always wear protective gloves, clothing, and eyewear when performing any installation
operations.
D If hoisting the valve, use a nylon sling to protect the surfaces. Carefully position the sling to prevent damage to the
actuator tubing and any accessories. Also, take care to prevent people from being injured in case the hoist or rigging
might slip. Be sure to use adequately sized hoists and chains or slings to handle the valve.
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 Automation Solutions
sales office.
CAUTION
D When ordered, the valve configuration and construction materials are generally selected to meet particular pressure,
temperature, pressure drop and controlled fluid conditions. Since some body/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 Automation Solutions sales office.
D Ensure that the valve and adjacent pipelines are free of foreign material that could damage the valve seating surfaces.

Maintenance
WARNING
Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before performing
any maintenance operations:
D Always wear protective gloves, clothing, and eyewear.
D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the
actuator cannot suddenly open or close the valve.
D Use bypass valves or completely shut off the process to isolate the valve from process pressure.
D Do not remove the actuator while the valve is pressurized.
D Relieve process pressure from both sides of the valve. Drain the process media from both sides of the valve.
D Vent the pneumatic actuator loading pressure and relieve any actuator spring pre‐compression.
D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
D The valve packing box might contain process fluids that are pressurized, even when the valve has been removed from the
pipeline. Process fluids might spray out under pressure when removing the packing hardware or packing rings, or when
loosening the packing box pipe plug. Cautiously remove parts so that fluid escapes slowly and safely.
D Many valve parts that are moving can injure you by pinching, cutting, or shearing. To help prevent such injury, stay
clear of any moving part.
D Never apply pressure to a partially assembled valve.
D To avoid personal injury or property damage caused by uncontrolled movement of a valve bonnet, loosen the bonnet by
following these instructions: Do not remove a stuck bonnet by pulling on it with equipment that can stretch or store
energy in any other manner. The sudden release of stored energy can cause uncontrolled movement of the bonnet.
Loosen bonnet nuts approximately 3 mm (0.125 inch). Then loosen the body‐to‐bonnet gasketed joint by either rocking
the bonnet or prying between the bonnet and body. Work the prying tool around the bonnet until the bonnet loosens.
If no fluid leaks from the joint, proceed with bonnet removal.
D As you remove parts, such as valve shafts, other parts, such as disks can fall from the valve body or suddenly move to
another position in the valve. To avoid injury from falling or moving parts, be sure to support parts and be sure they are
in a stable position as you disassemble the valve.
D Personal injury could result from packing leakage. Do not scratch the drive shaft or packing box wall while removing
packing parts.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
