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
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.
