Table 2-2:
Parameter type
Description
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.
Corrosive service
Select the material compatible with the specific processes and
atmospheric environments. Implement a periodic inspection
and maintenance program to ensure that pressure retaining
components are free from corrosion and erosion.
The valve is not designed with corrosion allowance. Inspect the
valve's metal parts periodically for corrosion and erosion, and in-
spect the seals and O-rings for wear and chemical deterioration.
Populated areas
For new installations, locate the control valve to an area that has
fewer than 10 buildings intended for human occupancy within
an area that extends 200 meters (220 yards) radially from the
control valve. (Reference: Class 1 Location: U.S. DOT, CFR Title
49: Part 192.5)
Closed, poorly ventilated areas
Install the control valve in a well ventilated area, not less than
one meter (approximately three feet) from source of ignition or
source of heat which might damage the unit.

fects of traffic.
