PLS TELL ME THE FUNCTION OR PRINCIPLE OF CREEP RELEIF VALVE....

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)
