FAIL OPEN (FO) CONTROL VALVE
FAIL OPEN (FO) CONTROL VALVE
(OP)
Dear All,
Is it safe for a steam turbine driven condensate pump (centrifugal type)
and lube oil pump (screw type)to have a fail open control valve upstream
of trip valve?
Thanks in advance...

If it ain't broke, don't fix it. If it's not safe ... make it that way.

Thank you for the quick reply, it helps me a lot.
Can i ask one more thing, how about a fail close on the cooling water supply for the bearing housing jacket?
Is it safer for these valves on the turbine bearing housing to be fail open? thanks in advance...

This is not a usual configuration in my experience, the cooling water usually just flows whether or not there is a process demand.
