What are the selection criteria for the various orifice diameter options for VX3 series 3-way valves?

The orifice diameter is the hole diameter at the narrowest point in the flow path, and it is related to the flow rate characteristics of the valve.
Basically, the larger the orifice diameter, the larger the flow. However, for the same model (e.g., the VX311□ and VX313□ are the same model, but the VX31□□ and VX32□□ are different models), the larger the orifice diameter, the smaller the max. operating pressure differential. Pay attention to the pressure conditions.
