How to Ensure the Airtightness of Valves That Have Been Used for a Long Time
Valves are core control components in fluid transmission systems, mainly used to control the direction, pressure, flow, and temperature of fluid in pipelines.
What Is Valve Lapping?
Valves often operate continuously under harsh conditions—such as high temperatures, high pressures, and mechanical stress—leading to defects on their sealing surfaces, including wear, deformation, scoring, or corrosion. Lapping is the core process for restoring valve seals. Through physical lapping, the valve disc and seat achieve a molecular-level fit, establishing a final line of defense against internal leakage and extending the valve’s service life.
