How to solve the leakage problem of pneumatic ball valve seal?

• Remove the screws, clean the pressure ring, replace the damaged parts, grind the sealing surface and the sealing surface of the connecting seat, and reassemble.
• For parts with large rust damage, it can be repaired by welding, bonding and other methods.
• The sealing ring of the pneumatic ball valve should be repaired according to the welding specification.
• When the surfacing welding cannot be re-welded, the corroded connection surface of the original surfacing sealing ring should be removed, and it can be repaired by grinding, bonding and other methods.
• The sealing and rolling leakage of the pneumatic ball valve should be fixed by rolling again with adhesive.
