Maintenance and troubleshooting of valves

Common problems with valves include internal leakage (worn sealing surface), external leakage (aged packing), and operational jamming. Regular maintenance requires cleaning the valve body, inspecting the seals, and lubricating the transmission mechanism. For corrosive media, corrosion-resistant materials (such as stainless steel and ceramics) should be selected; High temperature conditions require attention to the impact of thermal expansion. Timely replacement of worn parts and standardized operation can reduce unplanned downtime and ensure the safe operation of the system.
