Environmental conditions
Description
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.
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)
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.
