Note
For best shutoff performance and to reduce bearing wear, it is recommended that you install the valve shaft in a horizontal
direction. See figure 1.
5. Before installing the valve, make sure the flow direction arrow (key 32) on the valve matches the actual process fluid
flow direction through the valve for the application where the valve will be installed.
6. Install the flange gaskets and insert the valve between the mating pipeline flanges. For flangeless valve bodies, also
make sure the mating line flanges are aligned. Use flat sheet gaskets compatible with the process media, or spiral
wound gaskets with compression‐controlling center rings.
Ceramic Trim
Some types of ceramic trim, including the VTC (very tough ceramic) variety, can create a spark under certain
circumstances. When the edge of a ceramic part is struck against a second ceramic part with enough force, a spark can
be created.
WARNING
Avoid personal injury and property damage from ignition of process fluid caused by sparks from ceramic trim.
Do not use ceramic trim where the process fluid is unstable or if it is an explosive mixture (such as air and ether).
WARNING
The valve drive shaft is not necessarily grounded to the pipeline when installed. Personal injury or property damage could
result if the process fluid or the atmosphere around the valve is flammable, from an explosion caused by a discharge of
static electricity from the valve components. If the valve is installed in a hazardous area, electrically bond the drive shaft to
the valve.
