Causes and Preventive Measures of Steel Casting Valve Leakage
May 8th 2023
With the continuous progress of modern production technology, the quality requirements of valves are getting higher and higher. Due to the special structure of the valve, various casting defects will occur in the casting process, such as air holes, shrinkage cavity, shrinkage porosity and other quality defects, resulting in leakage of the valve.

Shrinkage cavity and shrinkage porosity are the main causes of valve leakage. In the casting production process, the formation of some casting defects, resulting in the use of valves in the process of leakage, affecting its normal use.
