Abstract
A method of manufacturing flow selector disk for a fluid pressure regulator, including the steps of providing a plate having a first face and a second face, and forming at least one baseline orifice in the plate including a first diameter portion adjacent the first face and a second diameter portion adjacent the second face. The first and second diameter portions are spaced a distance from each other to form an annular ring therebetween. A central flow portion is formed through the baseline orifice that is in fluid communication with both of the first and second diameter portions. The central flow portion has a relatively smaller diameter than either of the first and second diameter portions. The method also includes the step of plastically deforming a portion of the annular ring adjacent the central flow portion to thereby reduce the diameter of the central flow portion.
