    Does this container pressurized and if so to what pressure; and what type of cover seal are you using?

    Yes, it's pressurized about 16 bar and i am using rubber seal.

    Is it a flat gasket or O-ring type seal? Have you done the design pressure load and stress calculations for the cover plate?

    Multiply the pressure times the area inside the gasket to get the force trying to push the cover off the valve. The total clamp load of the bolts should be several times this value. How many times depends upon engineering judgement.

    So make the clamp load ten times the lifting force and see how it looks.
