Purging and Draining
PURGING
MOGAS coker switching valves are typically equipped
with steam purges.
To prevent valve lockup and ensure continuous
operation of these valves, it is highly recommended
that the purging process be
continuous
in the body
cavity area.
Note:
Review any job-specific or general arrangement drawings
provided for purge locations and procedures.
DRAINING
MOGAS coker switching valves are typically equipped
with drain ports, which will allow any coke and water
from the steam buildup in the body cavity area to be
flushed out at the end of each switching cycle.
The drains are to be opened, and remain open for
15 minutes after each cycle.
Note:
Review any job-specific or general arrangement drawings
provided for drain locations and procedures.
CAUTION!
It is
extremely important
to follow these steps to
ensure maximum valve performance and safety.
THIS WILL AFFECT THE VALVE WARRANTY.
NOTICE
Some MOGAS switching valves may have
automated purge and drain procedures. Consult
a MOGAS representative to learn more about
these options.
