Specifications
Specifications for these valves are shown in table 1 and in Fisher Bulletin 51.3:V150S Slurry Vee-Ball V150S and V300S
Rotary Control Valves (D103154X012).
Installation
WARNING
Safe work practices should be followed when handling the valve and actuator.
Some types of ceramic trim, including PSZ, can create a spark under certain conditions when an edge of one ceramic part is
struck against a second ceramic part with enough force. Do not use ceramic trim where the process fluid has volatile or
combustible properties.
The valve drive shaft is not necessarily grounded to the pipeline when installed. Personal injury or property damage could
result from an explosion caused by a discharge of static electricity from valve components if the process fluid or the
atmosphere around the valve is flammable. If the valve is installed in a hazardous area, electrically bond the drive shaft to
the valve.
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
Personal injury or equipment damage caused by sudden release of pressure may result if the valve assembly is installed
where service conditions could exceed either the valve body rating or the mating pipe flange joint rating. To avoid such
injury or damage, provide a relief valve for overpressure protection as required by government or accepted industry codes
and good engineering practices.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.
CAUTION
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. 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
