The pipe should be cleaned before installation to prevent impurities or particles from damaging the sealing surface of the safety valve.

Maintenance:

Check the working status of the safety valve regularly to ensure its normal operation.

Check whether the sealing surface of the safety valve is damaged or leaking.

Clean safety valves and pipes regularly to prevent clogging and damage to valve sealing surfaces.
