What advantage do ball valves have over other manual refrigeration valves?

Ball valves are particularly advantageous in refrigeration systems primarily because they offer less resistance to flow compared to other types of manual valves. This is due to their design, which features a spherical closure element that allows for a straight-through flow path when the valve is fully open. The minimal turbulence and friction during operation make it easier for fluids to pass through, enhancing system efficiency and reducing energy consumption.

In addition, the low-pressure drop across the valve contributes to better overall performance in refrigeration applications, ensuring that the system maintains optimal operating pressures and temperatures.

While factors like ease of operation, compact design, and cost do play a role in the selection of valves, they are not as impactful as flow resistance when it comes to the specific advantages that ball valves provide in refrigeration systems.
