Answer / ramdas a. wani

I have checked the correct answer. The creep valves are
safety valves installed in gas lines downstream of the PCV
( pressure control valve ) When the PCV is unable to
maintain the downstrem pressure and it exceeds a set limit
the creep safety vlave releives the excess pressure and
maintains the line pressure.
The defination is also given in the petroleum and natural
gas regulatory board notification of 2006 ( 19 of 2006)

Answer / millan

A relief valve which is installed and sized to protect
against the build up of downstream pressure due to a
regulator's failure to lock up. This type of relief is not
full fault protection.
