Environmental conditions Table 2-2:
Parameter type Description
Severe service conditions Ensure that piping or other attachments connected to the valve
are not under stress. The design of the control valve has not
been assessed for the effects of wind, earthquake loading and
severe weather conditions.
Additional severe service condi-
tions The valves are designed to be used on liquid applications for
crude oil and refined products.
The use of aggressive additives or oxygenates requires the use
of the Aggressive Products (AP) option. The AP option valve cyl-
inder incorporates cup-seals (PTFE Bal Seals) and an O-ring
made from appropriate materials for severe conditions. Materi-
als for pilots such as Low Swell NBR (main valve static O-rings)
and FFKM or PTFE are available.
