Process for manufacturing valve trim assemblies

A process for manufacturing a valve trim assembly comprising:

• providing a flow disk having an outer diameter, an inner diameter, an outer disposable flow disk portion, and a plurality of outlet passages, wherein each outlet passage has a terminal end, and wherein said terminal end does not extend to said flow disk outer diameter;
• providing a separation disk having an outer diameter and an inner diameter, wherein said flow disk outer diameter is greater than said separation disk outer diameter, and wherein said flow disk inner diameter is greater than or equal to said separation disk inner diameter;
• stacking said flow disk on said separation disk;
• securing said flow disk to said separation disk;
• removing said outer disposable flow disk portion at least as far as said terminal end of said outlet passages creating a reduced flow disk outer diameter that transects said outlet passages, thereby creating a flow disk island between adjacent outlet passages;
• and
• stacking an additional disk adjacent to said flow disk to form said valve trim assembly, wherein said additional disk is selected from a separation disk, a top disk, and a bottom disk.
