Key to charts on page 11:
The product must not be used in this region.
Graphite stem sealing is required for use in this region. Note: As standard the KEA,
KFA, KLA series two-port control valves are supplied with the PTFE stem sealing
option.
The product should not be used in this region or beyond its operating range as
damage to the internals may occur.
