all 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.

Forged steel Reduced Port Ball Valve
Forged steel Reduced Port Ball Valve is a valve with closed components to control flow. The flow area of the opening of the closing element is less than that of the inner diameter of the pipeline. For example, the onset of a linear globe valve or the sleeve passage of a cock valve has the same flow area as the valve inlet and outlet endoscopes. This throttling can make the valve pressure drop when the material flows through the closed element, and can restore part of the pressure when the fluid passes through the throttling zone.
The main purpose of Forged steel Reduced Port Ball Valve is to control flow through reducing flow or closing flow, such as globe valve, which is equal to adjusting the closing element so that the valve can provide different flow at a certain opening.
