Question:

Does the valve body have trachoma and air holes that reduce the local strength?

Does the valve body have trachoma and air holes that reduce the local strength?

Answer:

if used in low pressure medium, trachoma will leak, because of the role of cavitation, trachoma leak will be more and more big.
If it is used for high pressure media, can directly in trachoma explosion;
Must be reduced, once the valve body is found trachoma, the valve will be scrapped, the valve dissolved, re casting.
