Ball valves for conveying viscous and slagging-prone media should
be full-diameter, which facilitates regular wax scraping and
blowing through the pipeline. Diameter reducing ball valves are
suitable for pipes conveying gas or medium whose physical
properties are similar to water, because their weight is about
30% lighter than full diameter ball valves, which is conducive to
reducing pipeline load and cost. But for pipelines that need
regular pigging, no matter what medium is transported,
full-diameter ball valves must be used. According to API6D
standard, ball valves have necking and full diameter, necking
valves in DN300 and less than one specification, 250-600
shrinkage two specifications, more than 600 according to the use
of the decision.
