Hi,
Just wondering if some one can advice me
all my colleagues don't agree with me, but they do open an 8" pneumatic actuated discharge valve (which holds 60 bar of liquid from going to the (depressurized after maintenance) pump. and they say to me no worry the (Swing type) check valve will hold the pressure.
I don't agree with them.
what I know is that check valves are made to hold back flow, not back pressure with 60 bar difference.
is that ok? will it effect the pump on the long term?
by the way as per the process lines there is no pressurising line, its a really very old plant.
sorry for any grammar/spelling mistakes.
3 years working as an area operator in a gas plant.
Thank you
