Damage to the ball valve seat

For a floating ball valve, DN80, under 1 MPa pressure, during the process of opening it in water, the upstream seat broke. Has anyone encountered this kind of problem? How was it resolved? Thank you

It needs to be discontinued and replaced... There’s really no other solution. However, the cause of the fracture needs to be determined: was it due to vibrations? Pipe support, stress issues? ? ?
