    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.

    Spring Return Type
    I'm considering the ATO-PBV-200A pneumatic ball valve. Do you have a spring return type (not a double-acting type) option?

    ATO Responded
    The ATO-PBV-200A valve can be customized with a single-acting spring return actuator. What type of ball valve do you offer? How many units do you need?
